The Cushcraft 40-2CD and XM-240 use identical loading coils on the driven and reflector elements to help shorten the overall element length. The original design of the loading coils used a sheet metal screw to attach the wire coil to the aluminum element. Even though it is covered by heat shrink tubing, it becomes a point of failure when the sheet metal screw begins to corrode.
I recently rebuilt two 40-2CD antennas and had the need to renew the loading coil connections.
The first step is to remove the screw and clean everything up.
Drill a hole through the element. This will allow use of a stainless steel nut and bolt for a much more secure connection. I used a washer to help hold the wire. Also applied a dab of SS Jet-30 to improve conductivity.
I then used some rubber liner tape to wrap the connection point to make it as waterproof as possible.
I then used some 1.25″ heat shrink tubing to cover the complete loading coil.
Simply repeat this process for each loading coil. This small effort will prevent a common failure point for the 40-2CD antenna.
Sorry I didn’t record all the part sizes that I purchased at the local hardware store, but here they are in a photo.
For reference, here is a loading coil with all of the shrink wrap tubing removed.
This is a continuation of the story of my project to replace one of my ham radio towers. Read part 1 first.

I got a great deal on some LDF5-50A 7/8″ hardline. It arrived in two pieces, but as luck would have it, they were both perfect for what I needed. The 240′ run got to the base of the new tower. The 290′ run got to the base of the tower with the TH7, A3WS, and 6m beam.
Needed connectors and found some on e-Bay. Minimal instructions. Finally found a manual from Andrews about installing connectors that filled in some of the gaps. Took me a few tries to figure out the proper way to install them. Hoping the hardline will provide a significant improvement in loss over the previous 75 ohm CATV feedline.
July 24, 2022
I continued working on trying to convert the two and a half used 40-2CD antennas that I had on hand into the making of a new one. The biggest challenge is getting the driven element separated from the insulator (used a hammer), and getting the reflector and boom pieces apart.
Then I washed everything and started reinforcing per the W6QHS article recommendations. Having the extra element pieces was very helpful.
August 13, 2022
Finally got all the bits and pieces together to make a complete 40-2CD with heavy-duty reinforcement. Assembled everything at the 5-foot level on the tower.
Grabbed the AA-54 to check the SWR and was happy to see it look very similar to how the first antenna did when it was at the same mounting height.
August 14, 2022
Mark KA1YQC and John KF1KI arrived on a beautiful Sunday morning to help with the antenna raising. The first order of business was to remove the 4-ele 10 that had been installed at the 70′ level. After several evenings of studying plots using the HFTA Software that comes with the ARRL Antenna Book, I realized that the 40 needed to be at that height. The two 10-meter beams were better off lower on the tower.
You hate to go backwards on a project, but it seemed easier to take this antenna down rather than try to work around it.
The next step was to raise the side mount that would hold the lower 40.
Then it was time to raise the 40-2CD. We thought about using a tram, but it seemed like it might be more trouble to set up than it would save in time. Decided to corkscrew the antenna through the two sets of guys. This was complicated a bit by a close tree that snagged the elements a few times.
John and Mark did a great job of lifting and lowering as needed. And watching for times when the antenna would snag something behind my back.
Happiness is finally getting the antenna onto the side mount. The reflector was clear of guy wires and trees, but the driven element was much closer to the guy wires than I had expected. The use of Phillystran for the guys will prevent any performance issues, but we don’t want the antenna rubbing the guy wires in the wind or under snow load. Might have to raise the antenna couple of feet to get more clearance. Something to keep an eye on.
I was anxious to check the SWR now that the antenna was in position. It dipped exactly where I had hoped!
Nothing like coming down the tower and being able to take that first look back up to see the results.
It was only noon so we moved on to raising the two 4-element 10m beams into position. This was a piece of cake compared to the 40!
With all the antennas installed, we called it a day. I came back out to the tower later that evening to see a beautiful sunset that really highlighted the full antenna compliment.
Worked on making the phasing lines for the 40m stack. Will write a separate blog post on that topic.
The stacking switching is fairly simple and uses just coax phasing lines.
Switching uses an RCS-8V 5-position remote coax switch that I purchased used from W1DXH. The RCS-8V can be easily modified to have any of the switch positions be shorted or open when not selected. Will use some existing rotator cables to get the needed 6 conductors from the box back to the shack.
Mark KA1YQC came over to help me get the cables and relay box installed for the 40m stack. Not a hard job, but nice to have someone on the ground to send the cables up as needed.
Replaced the temporary coax from the top 40 with a piece to get to the switch box.
Installed the switch box.
Installed the phasing lines. For now, they are just coiled up and tied off. Wanted to make sure things were working before tying things off.
I wanted to have equal lengths of feedline for each antenna. And for those lengths to be a multiple of a 1/4-wave. That means the low antenna has about 50′ of extra coax, but it worked out great for getting down from the top antenna.
We wired the control line back to the shack and were prepared to see success. The top position worked. The lower position worked. But not both. Argh. Checked the control voltages and they were correct going up the tower.
Climbed the tower to inspect things. Discovered the t-connector had failed. Argh. It is the one that has 3 female UHF connectors that ties the 3 phasing lines together. A new t-connector is now on order. (I should have known better than to use a cheap one I found in my junk box.)
The good news is that listening to Europeans in the early evening shows the low 40m being the best antenna at times. Will be interesting to see if/how this changes as we get into the contest season and operate the whole opening from our sunset to European sunrise.
Checked the SWR on the two lower 10m beams. The middle one looks ok. The bottom one is resonant way below the band. Could be interaction with the metal guy wires that are within inches of the elements. Will do more work with HFTA to see if that antenna can be moved up or down the tower.
September 4, 2022
While waiting for Amazon to deliver, I went up the tower and refactored all the coaxes around the 40m switch box. With a few days of rain in the forecast, I wanted to get all of the connections secured.
Amazon arrived while I was on the tower, so with the sun just going over the horizon, I made one more trip up the tower to install the new t-connector.
Argh. Still a problem with the both-position on the switch. And to make things worse, the high antenna only wasn’t working either.
September 7-9, 2022
Multiple trips up the tower to try to diagnose the problem. I probably made 6-8 climbs to the 70′ level and was up there for several hours. Just couldn’t make sense of what I was seeing.
When checking the wiring, I discovered that a wire had pulled out of the splice junction at the base of the tower. That fixed the antenna 1 problem.
I got some good advice from W2SC and N2NT on things to try for the phasing lines. Eventually tracked the problem down to a missed solder connection on one of the PL-259 connectors! I usually solder the shield and then wait for the connector to cool before doing the center conductor. Somehow I missed doing this one.
When you test quarter wave coax lines, you look for an open on the analyzer. When I checked the cable from one end it looked fine. But, if I plugged the analyzer into the end with the missing solder, it showed there was no cable. I guess you have to test phasing lines from both ends…
Once I found and fixed that, I was happy to come down to the shack and hear all 3 positions of the stack were working. SWR was good from 7000 to 7250. All positions of the new stack are better than my original 40-2CD on another tower. (It must have a problem?) The stack position seemed to be slightly better most of the time. Spent some time on 40 SSB in the WAE contest and the stack seemed to be a winner compared to the top or bottom antenna alone. Thrilled to finally see success after all this effort.
September 10, 2022
Mark KA1YQC came over on a beautiful Saturday morning to help me work on the 10m stacking.
We moved the lower 10 from 29′ to 32′. This got it out of the guy wires and just above the first set.
Then we installed the WX0B Stackmatch box at the 65′ level. Checked SWR on each antenna as I did so. The bottom 2 antennas are resonant below the band. Is this caused by having Rohn 45G going through the middle of the antenna? Something to investigate.
We connected the control cable and headed back to the shack to check out work. All 3 positions could hear band noise. We listened to PT5J work Europeans in WAE. May need to investigate the wiring or the box as it didn’t seem like the right antenna was being selected as I switched through all the options. But, SWR was good across the band on all 3.
The last task was to raise and reattach the 160m shunt feed. This took no time and we were pleasantly surprised to find that the antenna was resonant around 1800 Khz. I had been afraid that adding 10′ to the tower and the second 40 would change the electrical height of the system. Will wait for dark to see if the antenna works.
Really enjoying having Mark’s help to take advantage of the fantastic early Fall weather to get things done before it gets rainy, cold, and windy in October.
October 21, 2022
On what is sure to be the last perfect day of the summer, Mark KA1YQC came over to help debug the 10m stack. We quickly determined there was a broken wire somewhere in the 250′ of cable between the shack and the base of the tower. It was the line that switched the toroid in the Stackmatch out when feeding a single antenna. No wonder the SWR and antenna selection was so weird. We grabbed a spare wire from the control cable to the 40m switching and things started working better.
The SWR on the low antennas was below 28.o Mhz. They resonated higher when tested at the 6′ level, but the extra height, guy wires, or Rohn 45 going through the middle was having an impact. We shortened the driven element on both antennas so they were resonant around 28.2, which kept the SWR relatively low from CW through 28.5 Mhz. Luckily this just meant rotating the driven element so both ends of the element could be reached from the tower.
Testing from the shack indicated there was something wrong with the low antenna. It sounded quiet and the SWR was height. We know the SWR was good using the antenna analyzer at the feed point, so it has to be in the coax or the Stackmatch. No amount of wiggling or unscrewing seemed to make any difference. So more diagnostic work needs to be done.
We also tried to find the tap point for the 160 shunt feed. We thought we had it, and then realized we did not have a solid connection from the feed point shield to the tower. When we added that, the R value was around 18 ohms. The tap point needs to be raised, but with sunset approaching, we decided to save this for another day.
Finish the 160 shunt feed mounting and tuning.
Clean up all the cable runs back to the shack
Thank you all for following the journey to this point. It has been a lot of work, but the kind that I really enjoy. Nothing has more hope than a new antenna system!
A very entertaining contest. Summer conditions always offer a few surprises and this contest had lots of them.
My summer project was to replace one of my towers (see https://k5zd.com/tower-replacement-project/). Things are not completely rebuilt, but I had antennas for all 6 bands. This contest was to be a test of the new 40 and 10m beams. Happy to report they appear to be worth the effort.
The contest started well with 10 and 15m open. It got slow in the mid-day and then just kept getting better as Europe turned its attention to the West.
Our town had its 4th of July fireworks show Saturday evening. I took a break to walk the 1.8 miles to the show and back. Was a perfect evening outside and the walk cleared out the contest fatigue. Lost just over 2 hours of prime low band mult hunting.
15m produced some deep Asians late in the evening and 20m was great all night.
Then 15m really opened the last 2 hours of the contest with the band open deep into UA/UA9!
I want to put up another 40m beam. Not comfortable doing it on the Rohn 25G tower that I have.
I had the opportunity to obtain 100′ of Rohn 45G from John K1AE. He lives about an hour from me. Making multiple trips and with a lot of help from YCCC club members, I was able to get the tower down over a 4-week span. I also purchased a Cushcraft 40-2CD that he had on the ground. I rented a U-Haul van to transport everything (tower, guy wires, beam) home.
Took advantage of some nice Fall weather to touch up some rubbed and rusted spots on the tower so it was ready to go.
A tree falls over and lands on one end of the stack of 40-2CD aluminum. Argh. The only “safe” place for antennas is in the air!
April 15, 2022
With the 3-day Easter holiday, I solicited help on the YCCC email list. Received a lot of generous responses and offers to help.
Martin AA1ON, Mark KA1YQC, and John NN1SS came down and we got started. We made much more progress than I expected – removing all antennas and getting down to the 60’ level.
In order, we removed:
80m dipole (freeing it up from the tree that had captured the feedline)
80m 4-square that was hanging from ropes strung out from the tower
160m shunt feed
Two 4-ele Cushcraft 10m beams that were side-mounted
6-ele 10m beam
We corkscrewed the beams down the tower. 10 meter beams are so easy to manipulate…
Weather was sunny and nice, except for the occasional gusts over 25mph. Nothing like being 80’ up with the top set of guys removed and the wind deciding to blow harder.
One lesson learned. When a tower is a bit floppy, it is hard to get the sections to wiggle apart. NN1SS brought a Tower Jack and that saved the day. Sections that were more stable close to a guy wire wiggled right apart.
After everyone left, I took advantage of the nice weather to prepare the guys at 60′ for removal and installed the temporary guys at the 10′ level.
April 16, 2022
When I installed this tower in 1994 I had purchased a 1/4″ wall 12′ steel mast. Weighs just over 100 pounds. Never used it. Has been imprisoned in the tower ever since. I was a bit worried if the two of us would be able to handle it.
Martin arrived about 9am, and we had the last 60’ down in about 2 hours. We pulled the mast out of the tower when we got to the 20′ level. I won’t say it was easy, but the two of us managed it without incident.
We were so far ahead of schedule that we had just finished when Ken WO1N arrived. I feel bad for letting him make the drive down.
I am now without antennas for 80, 30, and 10 meters. The crazy things we do to be just a little bit louder. 🙂
April 19, 2022
Made a run to visit Dave K1ZZ and pick up a 40-2CD antenna that he had been storing for Mark K1RO. “Storing” for the past 25 years! The antenna was in great shape and, after some hardware replacement, will soon be at the top of the new tower.
April 21, 2022
My friend Ron brought over his chainsaw and we took on the job of removing trees that had been growing into the guy wires. Always afraid of cutting down trees near a tower, so wanted to take advantage of this opportunity to clear things out a bit. Was perfect weather for getting the job done.
These were big trees. Glad to get them down before the leaves came out.
April 23. 2022
Another great day to get some work done.
The original tower base was big enough to support Rohn 45, but I wanted to make the base a bit bigger to provide more support. Let me just say it is a long carry to get concrete from the driveway near the house to the tower base. A 350′ carry that is uphill all the way.
May 3, 2022
Spent some time taking the 40-2CD from K1RO apart and cleaning it up.
May 17, 2022
After two weekends lost due to some international business travel, it was time to get back to work. Started making up the Phillystran portions of the guy wires. Hard to believe DX Engineering gets 270′ of Phillystran on that small spool!
Will use Phillystran on the top two sets of guys. 60′ for the top set and 30′ for the middle set. Will go with steel wire broken up every 28′ for the bottom set. Why 28′? Because that is the length the guy wires from K1AE were already made.
May 20, 2022
Mark KA1YQC came over and we hauled a few Rohn 45G sections up to the tower location. Then we put up the first section of the tower and installed the temporary guy wires at the 10′ level. Made everything tight and straight.
Spent the rest of the evening wrangling guy wires. Added the steel portion to the Phillystran. Replaced a few pieces of guy wire that showed signs of age.
Ready to start stacking tower for real tomorrow.
May 21, 2022
Joe KM1P, John KF1KI, and Spence AB1HO arrived to a cloudy and cool morning around 10 am. We quickly got 4 sections stacked up and the first set of guys attached by a little after noon. The clouds cleared and it became noticeably hotter. We finished tightening the first set of guys and removed the temporaries. By 1:30 it was hot and we had enough.
One thing that slowed us down was guy wire lengths. The steel guys were broken up every 28 feet. When we pulled them out to the North and Southwest guy points, the insulator landed right at the turnbuckle. We had to undo the guy grip and change the length of the final segment from 28 to 22 feet. I probably should have done more math and anticipated this issue in advance…
May 22, 2022
It was a sunny warm day when Martin AA1ON, Mark KA1YQC, and Lars KE1J arrived around 9 am. The forecast was for temperatures into the 90s. I was a bit surprised everyone showed up!
Each new section was the same dance. Set up gin pole. Ground crew cleans out tower legs and puts in White Lithium grease. Pull up section. Get the sections to mate. Put in the small bolt for each leg (Rohn 45G has a large bolt and a small one for each leg). Then put in the large bolt for each. A drift pin is an essential tool for getting the holes to align. And a hammer to help the bolts power through the holes. Then tighten the bolts for each leg. Reposition the gin pole and repeat.
We added 3 more sections, reaching the 70′ level. The second guy bracket was at 65′. The second set of guys had 30′ of Phillystran and then steel broken up with insulators down to the anchor. There were two guy wires where an insulator happened to be in the wrong place and required modification. We methodically made our way around the 3 guy points tightening turnbuckles while confirming the tower was still straight. The Loos tension gauge confirmed the guys were at the proper tension.
We took a short break as it was starting to get very warm.
Back up the tower to do the next 3 sections. We had decided to put the rotator plate and the guy bracket on the top section so I wouldn’t have to assemble them on the tower. Great idea, but the extra weight, and the 90′ pull, almost put the ground crew into the red zone. Of course, when the section got up there, it didn’t want to mate to the previous section. This required another heave to pull it off so I could spin it and try again. Oh, did I mention the wind came up while this happening?! I tried not to notice the subtle rocking that was taking place without the top set of guys in place yet… Nothing better than to get the legs aligned and then hear that satisfying thump when the section drops down to its proper place.
The ground crew did a great job. The breeze I was feeling on top of the tower was not so much down at ground level. The guys were pretty spent when we decided to stop.
An empty tower is like a blank canvas. Ready for something great to be created. It was a very good day of progress. Tower only needs to have the top plate installed to be complete.
June 1, 2022
Finally back to working on the 40-2CD. The main work was to replace the aluminum truss Cushcraft provides with some stainless steel cable and hardware.
June 6, 2022
Guy wire day. Focused on keeping the tower straight while also getting each guy wire to the proper tension as measured with the Loos Tension Gauge. Had one guy wire that needed to be adjusted as the turnbuckle had run out of room.
June 7-9, 2022
Rebuilding the 40-2CD. Carefully measured out each piece. Added reinforcement tubing inside the elements as possible. A dab of SS Jet 30 at each joint for long term connectivity. Also a stainless steel sheet metal screw to keep the pieces from coming undone.
I could not get the driven element pieces off of the center insulator. The only way to get the reinforcement piece in was to measure, mark it, then drive the piece of aluminum down the inside of each element. Had to be careful not to push it in too far as there was not going to be a way to get it back out. Added additional reinforcement to the first few element joints. The element is much less floppy than before the modification. It’s not the full W6QHS treatment, but hopefully, it helps with long-term survivability.
June 10, 2022
Hauled the boom and elements up to the tower. Assembled everything to make sure I had not missed anything. The 40 is ready.
Jun 11, 2022
I was up early making final preparations for the 40m beam. Got the choke installed and enough feedline to get just above the top plate. I have learned the hard way not to end up with a coax joint in the middle of the rotator loop!
Trying something different with the choke. K3LR has reported some improvement in the choking impedance if the choke is separated from the boom. I put the choke inside PVC and used some rubber spacers to get it about an inch away. Maybe not quite enough separation, but good mechanically.
SWR looks good, but hard to know with the antenna so close to the ground.
Martin AA1ON, Mark KA1YQC, and John KF1KI arrived around 10am. A bit of a delay as I made multiple trips back to the house for forgotten tools or parts. Started climbing around 10:40am.
First order of business was to install the top plate.
I had not fully accounted for the size of the rotator when I selected the original location of the rotator shelf. Took a few minutes to move it down one rung.
Then it was time for the mast. The ground crew hauled it up the tower without incident. They said it was much easier than the top section with guy bracket was! It was then that I discovered another engineering error on my part… the clamp holding the rope onto the mast hit the gin pole pulley with another 4″ of needed height still to go. Arrrggh! Luckily it was just close enough that I could lift the mast onto the top plate. After several tries and some colorful language, I was able to lever the mast up to the thrust bearing, then the bolt, then to the rotary part, and finally, with one huge grunt, lifted it over the edge and into the hole. Mission accomplished! I was determined not to make the guys have to lower the mast and lift it again. But, it was probably not the smartest approach. Next time, measure first!
Next up was to raise the 40-2CD. There is a pine tree that reaches in just enough that I wasn’t sure I would be able to easily corkscrew the antenna up the tower. Those capacitance hat rods on each element seem to always find any obstruction. I made the decision to assemble the beam on the tower. We pulled the driven element up first, then attached it to the tower with a strap and carabiner. Then repeated for the boom and reflector. I then attached the elements to each end of the boom.
Once the elements were attached, it was simply a matter of rotating the antenna to horizontal and dropping it onto the mast. The team on the ground was very impressed with the maneuver and how well it worked out.
With the antenna secure, a call went out for the antenna analyzer to be sent up to see some early results. The SWR was very good, with the resonant frequency about 20 Khz lower than expected. Is it worth trying to adjust the driven element length?
Of course, once we think everything is done and are ready to declare success, I noticed a small problem with the way I assembled the driven element. It is shifted about 1/2″ to one side, making the feed point attachment uncomfortably close to the u-bolt. Maybe not a big problem, but the u-bolt was a bit crooked. This will get fixed during a future session when we are ready to raise up the 10-meter Yagi.
June 15, 2022
I was joined by Mark KA1YQC to make the trip up to K1AE to pick up some 7/8″ hardline and the remaining pieces of another 40-2CD. We were met there by John NN1SS who helped load things into the U-Haul.
This is some serious hardline. I just hope there is enough to get a single piece that goes from the shack to the 10m beams that will be on the new tower (250+ feet). And that I can find some connectors!
June 18, 2022
I was joined today by Martin AA1ON, John NN1SS, Mark KA1YQC, and Spence AB1HO. It was a very cool day for mid June with a high temperature expected only in the mid-’60s. We had a stiff breeze from the NW once I cleared the top of the trees.
The first job was to fix the 40m driven element mounting. Popped the 40 off the top of the mast and was easily able to get to the feed point and slide it over about half an inch. Then popped it back on.
We brought up the Yaesu G-2800 rotator so I wouldn’t have to untie the rope until it was installed. We then raised the mast. This went very well, except for the few times I made the ground crew back up a bit because I didn’t tie the rope in the right place or forgot to tape the coax as the 40-2CD went up. Once the mast cleared the rotator plate, I was able to insert the rotator easily into the tower. I had a bit of an incident while putting the bolts in. I had left them in the plastic bag as they came from Yaesu. At one point I turned my hand so the plastic back dumped a few bits. They fluttered to the ground and left me one bolt short of having all I needed. Argh!
The DX Engineering thrust bearing to hold the mast at the top of the tower is a thing of beauty. But, the opening is slightly bigger than my 2″ steel mast. This put all of the weight on the 3 stainless steel bolts. Since the mast is so heavy, I didn’t want to take any chance it would slip. I added a safety u-bolt around the mast.
With the rotator secure, I climbed down for a break and to prep the 10m beam to go up. It was mostly ready, but I wanted to check the SWR before we got too far. Pulled the antenna up to about 20′ and the SWR minimum was way below the band. Not sure how that happened since the antenna was unchanged from how it came down 8 weeks earlier. We lowered the beam and started messing with the gamma match at the feed point. In the end, I think we shortened the driven element by 2″ or so on each side and moved the gamma shorting rod about a half inch. Looks much better on the AA-54, but not sure what we may have done to the performance…
The antenna easily corkscrewed up the tower and was bolted to the mast.
Up came the antenna analyzer and it was great to see both antennas had the expected SWR.
It’s always nice to come off the tower and get to take that first look up to see the result.
The heavy work was done so we headed off to the local hamburger place to celebrate.
June 24, 2022
Dragged the rotator cable up the tower and connected the rotator. One continuous 350-foot piece of control cable to reach the shack. Was a bit disappointed to find the rotator would not turn. I had tested the full length of cable before I put it up, but maybe the wiring inside the connector at the rotator lost a wire… disappointed.
June 25, 2022
Field Day weekend. Perfect time to make progress on antennas. I spent some time trying to diagnose the rotator problem. Finally tracked it down to a connection at my cable panel where everything comes into the house. Argh. Very happy to see beams turning!
Inspired, I climbed the tower to run coax cables for the 10m and 40m beams down to ground level. These connected up to the existing cables back to the shack. Field Day offered the perfect test for the new antennas. 40m worked great. Unfortunately, 10m was stone cold dead. Not even an FT8 signal! On Sunday the band was open and the 10m was confirmed to be working.
July 1, 2022
Mark KA1YQC came over to help get the 80m dipole reinstalled. This dipole goes between the two towers and required a bit of rope work to get the antenna tuned to the correct frequency and then worked around the trees. Nice to see a flat dipole at the 90′ level. This gets me back on all bands.
Mark also brought over a Cushcraft A3WS that he doesn’t need. This is a 12/17 meter duobander. I have never had antennas for those bands so excited to get it in the air and chase some new DXCC band credits.
July 4, 2022
Built the A3WS and made some QSOs on it at the 5′ level to confirm it was ready for action.
July 16, 2022
Mark KA1YQC came over today. The first task was to install the A3WS at the 30′ level on Tower 3. Decided not to put it at the top of this tower due to 1) concern about its wind survivability, and 2) don’t want to risk any interaction with the 10 and the 40.
That decision freed us up to install the 80m 4 square rigging. This consists of running a rope out from the top of the tower in 4 directions and then using that to hold the top of the verticals. Can’t quite get enough height to make them vertical, but enough so they work.
We had just enough energy to confirm the tuning on a Cushcraft 4-element 10-meter beam and raise it to the 70′ level.
K5ZD (op. K5ZD) in the Single Operator Unlimited (Assisted) Category, High Power. Read the post-contest writeup.
This was an SO2R operation. The audio is the same as heard by the operator. When headphones are ‘split’, the left channel is from the left side radio and the right channel is from the right side radio. The sidetone audio is very low so you may not always be able to hear what is being sent.

This was intended to be a casual fun effort. I started the contest calling JAs on 15m rather than running on 40. Once I did get to the low bands and started running, I was blown away by the rates.
Got to 160 at 0305z and called CQ. Could not believe how loud the Europeans were. It was a continuous run for the next 40 mins.
40 did its usual thing of staying open to Europe well past Eu sunrise. As a result, I stayed awake too long. So only got 90 minutes of sleep before I was up again. A quick sweep of the low bands and then arrived at a wide-open 20m at 1109z. Three straight hours over 200!
I was watching the scoreboard and keeping tabs on AA1K and K1ZZ along with AA3B. I seemed to be keeping up with them so that doubled my motivation. I had intended to stop around 1700z but had such a pileup on 20 that I couldn’t leave. Then was going to stop at 2000 QSOs, but still, guys were calling. Finally, took a break at 1849z with over 2300 QSOs. I guess you could call contesting an addiction for me…
Cooked dinner and had intended to go for a walk, but a snow squall came through. Looked nasty outside so got back on the radio. (Of course!) CQing on 20 with a steady rate and finally some time to use the second radio to tune for mults.
It is frustrating to tune around because no one seems to send their call anymore. It is just a steady stream of stations sending “TU”. Not a problem when operating with the cluster/RBN, but definitely a challenge without. I would work stations and try to get them to send their call. Sometimes I would have to wait several minutes to figure out who I had worked. Argh. (I have to confess that there were times when I had big pileups that I just sent TU at the end. It is a time-saver, but once rates slow down there really is no advantage.)
I was looking forward to getting going on 40, but another snow squall was generating so much static that I couldn’t hear anything. Spent 20 minutes watching the Olympics while waiting for it to end.
Was feeling pretty tired since I had not really planned my life around a full-out effort. Took a 3-hour break at 0200z. Came back on at 0500z to find 160 again in very good shape. Gave me another good run of stations including a lot of 100W guys and even a few QRP. 80 was good late with some Eu stations calling in almost an hour after their sunrise. 40m seemed a bit muffled, but still had stations to work until I finally stopped at 0830z.
Another short sleep and back on at 1030z. Worked two JA on 80 straight away. That woke me up! Got to 20m at 1043z and it was already packed with signals. By this point, I was looking competitive on the scoreboard so I focused on running as much as possible. 20m was open deep into Asia. Made the jump to 15m at 1224z and it was off to the races again.
10m had been open on Saturday morning. Mostly for calling the few south Europeans that showed up. Sunday seemed a little better. EF7N was loud and calling lots of unanswered CQs. I tried CQing with the second radio but not much luck. Did have HB0A call in so that was a good one. Since it didn’t seem like it was going to produce any rate, I turned my focus to running on 15 and 20.
Took a break at 1815z to make lunch and go for a walk. Nothing clears the cobwebs like 4 miles in 30-degree weather! Back on at 1955z to chase mults and eek out a slow run on 20m. One last break at 2130z and then it was a push to the end.
40m started out well, but then I just ran out of stations to work. Many unanswered CQs. Not much going on 80 either. Discovered the JAs were loud on 15m so used the second radio to chase them.
What had started out as a part-time effort with a goal of maybe 3000 QSOs ended up a pretty intense effort with over 4200! Much of it is thanks to the incredible activity from Europe. Especially the high number of QRP (5W) callers. And the ability to track the competition on https://contestonlinescore.com/
Bud AA3B has proven he can whip me in any RTTY contest so I was looking to try something different this year. With the improving solar cycle, I was hoping the high bands would be good enough to support some fun operating as low power. Unfortunately, they weren’t that good.
Started 30 minutes late. The contest was a grind from the beginning. Very few sustained runs all weekend. Spent a lot of time calling people. Lots of guys CQed in my face. Meant to stop before the end to watch the Super Bowl pre-game, but did that while operating. Some good mults called in during the last hour on 40m.
It felt like activity was down, but you wouldn’t know it from the QRM on 20m. I know my station is very loud on 20m. I couldn’t make a dent. Band was loaded from 14078 to 14150. Skip was short so the Europeans were having their own contest. I tried CQing high and low with no real success. Ended up calling a lot of guys.
Best part of the weekend was the openings to Japan. 15 meters was great both Sat and Sun evening. Even better on 15 than on 20.
As always, it was fun and motivating to watch the online scoreboard. The scores in WPX go up exponentially so when you get behind, it is hard to catch up!
Kudos and respect to all you guys that do RTTY contesting with 100 watts. I don’t think I have the patience for it. 🙂
