Recently checking audio drive to my K3 in support of JT65, I noted
the ALC meter not registering normal 4-bars stead 5th
flickering. Immediately checking audio level setting from my emu0202
soundcard (I use the headphone jack because it has an adjustable pot
for level = manual knob vs computer dialog window slider). Thus I do
not use the internal soundcard in my computer (crapped out years
ago). Emu0202 connects via USB port.
Next i checked audio lines. Then finally used a different soundcard.
All result in two bars showing on ALC meter and not adjustable. So I
am suspecting failure in the indication ckts.
Final test was doing some JT65 moon-bounce where my signal was
successfully received and decoded, indicating that I was probably
modulating properly. The peaking of the RF power meter looked right
(there is about 2% variation in power on Bird power meter in
conjunction with tones).
So what should I look for? Is there any menu setting that could be
incorrect? Or does this suggest component failure in ALC metering?
Remember that I have 14 years experience using JT65, and seven using
the K3 on JT65. Seems incredulous that I could be making a "pilot
error". But accidental button push is a possiblity. Yes, I tried
adjusting Line-IN with no indicated change on the ALC meter. This
was using a tone test/set up mode in WSJT providing steady single freq. tones.
