Hello All,
?
I purchased and built a low HF QDX and modified it with the JasonKits MOSFET PA.?
I am to the point of frustration trying to troubleshoot why the radio is not TXing.
?
It seems to receive well with the level at around 60-65dB (My FT857 will max the meter, but I'll take 60). When I attempt to transmit, I only get the 3 pulses of the red LED.
?
I have tried on both a Raspberry Pi running 73Linux as well as a Microsoft Surface Pro 4 running Win11. I have confirmed all volume controls are at 100% on both devices.?
I have double and triple checked my soldering and, while it's not pretty, I am moderately confident that there are no cold joints.
?
I have run the diagnostics on the terminal and don't see anything that is problematic as far as I can tell.?
I am seeing the same behavior on 20m and 40m.
?
Is there anything else on the hardware side that I could focus on that might be the problem?
?
?
TIA,
Mark
