Hi Lou,
thank you for your kind answer and suggestion.?
I 'm using? ?FT8 for approx 1 hour? sessions with battery and/or with AC (without charging the battery at the same time) and I was surprised not to detect any particular over heating. Rig is connected directly to PC? without CE19 device? (WSJT-X has X5105 in the list of preset TRX)? . As a precaution I let the rig having some rest from time to time avoiding continuos calls (in case nobody is answering me) .
Another positive thing is that measuring the power with a good power meter on some band I measured? ?even 7 watts of output.? I'm using the rig with a
the magnetic loop MC-20? or? with a short multiband vertical and it works like a charm. (in FT8 > 4000 miles far away,? in WSPR? 3watts? ?> 8'000 miles).
