Folks,
As the title says, USB on 20m and higher is not working. By "not working" I mean, in the USB mode there is no noise ... when I switch to LSB/CW/AM I get the usual noise and some activity, but alas nothing on USB.
Is this a known problem? Anything I can try before I send it in for repair?
Other that that problem there are no other problem whatsoever, power output, LCD, knobs and buttons all work great. No having USB on 20m and above is a big problem though
