I just got the radio back from service due to a blown U5. On AM/FM/USB/LSB I have good power out as shown by the SmartSDR program and the amp meter on my power supply. Using the FM mode when I key the radio I show 100 watts RF out and the PS shows about 20 amps.
However, when I try digital modes the program shows no power out and the amp meter on the power supply only shows about 5 watts of power used.
The RF power slider is set to max and my SWR is about 1.25 : 1 through the radios tuner to my 80M loop.
Before I sent the radio in for the blown U5, the digital modes had good power out as shown by both the program and the PS.
Mike, I have a level shown in the DAX control panel TX stream that is almost full scale. I show very little change in the radio level. Nothing like it was before sending the radio in.
Shut down DAX, SSDR and WSJT-X. Restarted them all. Still the same. I show almost full scale in the DAX control panel, not very much in the radio level. I am using FT8 mode and the isn't anything that shows audio level for that in the program.
Shutting down and restarting only DAX changes nothing.
Have a look at page 127 and see if you missed anything.
