K5ZD/1 Hardware Change Log
Construction of a successful station doesn’t happen instantly. Continuous improvements are the key to station maturity. The list below shows the station hardware at different points along the way.
Added 80m dipole between the two big towers.
Replaced WX0B SixPak with HamPlus 2x MBD-8E and AS-82F.
Replaced the FT1000D with an Elecraft K3 (and P3 pan adapter).
Purchased an AL-1500 amplifier.
40-2CD was intermittent. W2GD climbed the mast and rotated the antenna so I could replace the feedpoint and coax. Problem remained. Finally tracked it to bad hardline connector at bottom of the tower.
Purchased Elecraft K3 just before CQWW CW. A great radio!!
One of the capacitance hats on the 40-2CD fell apart. Managed to pull the beam off the mast and reach the point on the element so I could fix it.
40-2CD became intermittent. Had to lower the mast and work on it to find and fix the problem. Turned out to be a bad barrel connector (see picture). Now hoping I get another 12 years before I have to work on it again.
Purchased used Yaesu FT-847 so son Andrew (KB1NXJ) can enjoy his technician privileges.
Purchased Array Solutions BP-6 band pass filters. This is the set of W3NQN filters that are all in one enclosure.
Upgrading coax connections on 80 and 160 so they are on their own into the SixPak. Needed to do this to optimize SO2R switching.
Added W8JI mods to FT1000D. Mod to help close in strong signal response by turning off noise blanker and mod to reduce key clicks.
Put up 5-ele 6m beam above the TH7DXX at 45′. Got transverter and amplifier working, so now QRV on 6m.
New gamma match on 160m shunt fed tower and eliminated all cables coming off the tower above ground level. Added 32 1/4-wave radials. Antenna now works!
Bought Downeast Microwave 6m transverter, amplifier, and beam from K2UA.
Put up 80m 4 square hanging from 90′ tower. 8-12 radials on each element.
Replaced Create RC5A-2 on Tower 1 with Tailtwister. Create is great rotator but direction potentiometers keep failing.
Ran separate coax to 80m Inverted vee. No longer sharing with 20m.
Built switch to allow instant selection of South TH7 from either radio.
Purchased FT1000D from K2RD.
Purchased Array Solutions FM-6 band pass filter switcher. Used some ICE band pass filters that I had from WRTC-96 for 40-10 meters. Put this on the left FT-1000D.
Moved 6-el 10m up to top of 90′ tower. Installed two 4-el Cushcraft 10m beams at 30′ and 60′. Feed all 3 antennas through WX0B stackmatch.
Station 1 – Yaesu FT-1000D + Alpha 76CA
Station 2 – Icom IC-765 + Ameritron AL1200
