I earn part of my living in aeronautical HF since the early 80's. In the mid 80's the 30 kW PEP Telefunken self-tune ransmitters used in Sweden were upgraded with new exciters and a remote control sy
Hi all, I know a few stations running around 100 Kw in CB 27 MHz keydown contest, mobile and fixed. They use 3 x 3CX20.000 and 2 x 3CX20.000There are even more stations around 40 Kw (just one 3CX20.0
A few overseas US military stations were known to have run in the 20-50KW range when needing to clear a hole to pass traffic or run phone patches. Ive also heard of a small group who have former comm

About two years ago I was contacted by an Italian ham, who wanted my advice about how to wind a three phase high voltage power transformer for his amp. He reported that he was running 45kW, and that
I was doing a Multi with a station who had a 4-1000 amp. There was a station on 40 that we were trying to get and he kept turning the steering wheel on the power supply up and calling him. We finally
I seem to recall a ham in Texas back in the 80's during the heyday of 3.895 who was running a 3CX10000 driven by a Drake L4 resulting in ~28K out. Compared to some of the other comments here, that so
In relation to Tom's recollection of that 4-1000 amp, I remember the first time I saw someone using a tube with more than the spec sheet values on the tubes. In this case it was a friend who had a ho

Once you get over a few kW, things like feeders and antennas can get to be a problem. Plus you have to very well off to afford the electricity bill! G3SJX once somewhat tongue in cheek suggested the
Normally, a 10 - 15 kW output amplifier such as the Collins 208U-10 or the Harris RF-126 requires primary fusing using at least 63 A slow-blow to be able to cold-start without risking the fuses (assu
