Can you try the 2 tone mode and check the power output? Is it possible that there is a problem with the mic? The low level RF indicates that there is marginal output from the digital parts.
I would try another mic. Do not attempt any calibration.

I Just upgraded the software to the latest on github.? Then I Tried transmitting into a 10 watt dummy load and measuring power out on a qrp meter with various modes on 20m. With the drive set at 39 I was getting 7 watts out on CW, FT8, and PSK31 with both the radios meter and the qrp meter. Then I tried SSB with the supplied mic on various mic gain settings from 20-50. Neither of the power meters showed movement, although I could see what looked like random noise at a low level on the waterfall. I upped the drive but there was. still no power out. I¡¯ll try to look at the schematic tomorrow, but I have very limited skill in that area. Any ideas on how to fix this will be appreciated.? 73 Reed AA1RB
