K5zD, Saturday, CQ WW RTTY 2023

This was a casual effort that turned serious.  Didn’t do the normal sleep and food prep for a big effort.  Was looking forward to the contest, but didn’t expect to spend full-time.  Conditions on Friday night and Saturday were great. Lots of good openings and rates.  Only slept 2 hours Friday night and 30 minute break for lunch. I would have been very happy if it ended after 24 hours.

Line at 24 hours: 2166 QSOs, 183 St, 95 Zn, 276 Cty for 2,958,914 points

The second 24 hours were a bit of a slog.  Not helped when one of my amplifiers failed about 1305z. The power output went from 1400W to 2W. After spending an hour operating with one radio and thinking about quitting, I decided to pull a spare amp out of the closet and keep going.  I was back in full SO2R mode by 1500z.

Was entertaining to watch the race between K1LZ and AA3B on the online scoreboard. They really piled up the multipliers.  At one point on Saturday, I was more than 160 mults behind AA3B.  I made it my goal on Sunday to close the gap to less than 100.  You would think available mults are somewhat fixed, and I should be able to find some that he found using the cluster.  But, no matter what I did, I never made it to under 100 mults behind.  It was good motivation to keep me tuning the bands. Running on two bands very much limits the ability to tune around. You have to hope the mults call in.

The rebuilt TH7 now has an SWR problem on 10m. The amp didn’t seem to care and I was able to work stations to the south.

Nice JA run on 15m Saturday evening.  Almost all right at the noise level. It was interesting to see how the bands opened in the morning.  20m was open well before sunrise but didn’t last long after due to absorption.  15m was the daytime money band.  10m was good on Saturday morning, but not so much on Sunday.

Spent time checking which antenna was best.  For 10m, it seemed like the high antenna at 100′ was always better than the low stack or all 3.  On 15 and 20 the stack was always best.

Spent a lot of time chasing missing states.  Thought I was going to miss RI on 20m, but found NC1CC with an hour to go.  Was missing OR on 20m until N7DB called in during the last hour.  Didn’t hear a MT station until late Sunday and then got K7QA on 2 bands.  Only worked one station in DE. No contact with VT although I heard N1IBM work someone.

Always a fun contest.  The RTTY crowd is very proficient these days.  Except for those few guys who still insist on sending everything 3 times.  The biggest impediment to rate is my ability to type.  I would mess up a letter and the station I was working would repeat their call multiple times.  My bad.

This is a new personal record for this contest.
