My radio is transmitting fine on AM, however I don't think I'm transmitting on LSB what would cause that issue?
Thanks for the info, this is my original 980 as I haven't received my new setup yet. I followed your instructions and fixed the issue, I turned the talkback down because for some reason at volume 10 it was causing my transmit to sound bad.You're the one with the 980 and 250W amp right?
Check Mic gain, put radio on LSB or USB, use any external meter in line from your radio to the meter with coax to antenna - SWR meter? Yes even that one! Just switch to FWD and set CAL knob to about Mid point and key up and talk - does needle move? Good you're transmitting! Don't go overboard with it - take it back out and reinstall the antenna to radio.
If it don't - there is little in the way to hinder LSB from AM so it won't work. Else it is a switch or Mic gain issue. INTERNALLY - there are two controls but you wouldn't know if AM worked because if both controls are set wrong AM may have a carrier but no audio - that's called AMC - but if you had someone adjust it (Less' Customs) and turned it down too far, that may be the issue- that control is called ALC. That can prevent SSB audio because it's turned down too far. That is a mistake that happens often when people purchase a system that has an amp to go with it. The amp can take only so much power and POOF- SSB mode can produce that Poof power easily enough. The guy selling the equipment doesn't want you to blow it up but may have set the ALC control too low...
For if you can TX on AM and talk - then in SSB mode, the only different thing that has changed in all of this is the Carrier is removed. See ALC and AMC controls above...
So someone may have "tweaked" the RF meter in the radio. They turned it down too far and now it doesn't even light up.
