Pretty much the same here. KPA on top of KAT, but I run a TS-590 for the radio. Love the setup. I also work WSJTx and WSJT10 modes on MS and Es on six and ten. Duty cycles are "high" but I wouldn't consider them 100%. More like 50%. i.e. 5 sec on, 5 sec off, 15 sec on, 15 sec off, 30 sec on, 30 sec off. The fan does get to stage 4 fairly easily on six meters (for me). I run 430-480W out most of the time. I kick the manual fan setting to stage 4 when I start a run and if it takes too long, it will go stage 5 the last few seconds of each transmission and stay there until a few seconds (5 normally) after the end of transmission. When I'm done with the QSO, I move the fan back to normal. Starting with it on 4 just delays the onset of stage 5. I work very little JT65 and no PSK. I do work JT9g on ten meters and JT9h on six meters, but mostly JTMSK or FSK441 on six. The radio stays at 27 watts at all times. > I have owned many rigs and amps in my 62 years of ham radio and I personally > rate my Elecraft station as superior to all the others, names withheld to > protect the innocent. I'll echo Jim here too, but my years only total 56 in HR. The KPA500 was what finally got me to turn loose of my "I'll NEVER sell it" Johnson Thunderbolt that I used for so many years. > Just my two cents..... > Jim, W4ATK ...and mine.
