CQ WW DX CONTEST CW 2023

Technical problems was the main issue of this contest, Mr. Murphy was here again.

OM Power PA started to trip the breaker and to burn PA fuses. Longer heat-up solved it.
Then ACOM started to refuse autotuning. I used default settings. SDR RX used as panadapter stopped to work right before the start of the contest. Restart of everything at 00:00 UTC. Main monitor started to have few seconds blackouts every 5-10 minutes. RX verticals main preamp burned off on Saturday night, despite I played a lot with delays before the contest. Lost 80 minutes finding the reason and reconnecting of RX ANT to spare K9AY RX ANT. Two or three complete restarts of the whole PC due to frozen of something were only irrelevant issues.

Conditions were fine, but unstable. Solid low bands pileups on both mornings, then good JA openings of all high bands. Also NA openings were fine, but bands conditions went up and down unexpectedly.
Plus Aurora few times. Sunday was of a bit worse conditions. In general: good low bands, so improving of the high bands ANTs is my main goal.

Traffic was fine in general, not a lot of intruders, It wasn’t problem to find free frequency, callers came right after the first RBN spot (what a difference to SSB leg). Saturday was of running pileups, but S&P for mults was essential for final score on Sunday.

I often had problem to say to callers, that I didn’t receive their callsign. They sent exchange and went away no matter they didn’t hear their callsig played at all. I had to persuade them, that I didn’t have their proper or complete callsign. Few QSOs weren’t logged.

But contesting was good relax, as usually, including „faults stresses“, hi. Thank you for participation, guys!
