Yea, its just the audio is not making it through...
YEAH, I KNOW - JUST DON'T KNOW WHY
Do this, on the Audio out on the Rig blaster itself, connect some headphones and see if anything comes out.
I AN DECODING CW-RTTY AND HAVE SPEAKERS IN THE OUTPUT JACK OF THE RB AND CAN HEAR FINE...
The knob up front adjusts that signal coming in, so half way is a good start to adjust from there so the signal isnt hammering the radio coming from the computer.
ALREADY MESSED WITH THAT...SAME ...
Better yet, you hook up some speakers to the computer, can you hear it going bezerk when you transmit with the audio coming through it??
I THINK I FOLLOW YOU...WITH SPEAKERS CONNECTED TO COMPUTER OR, TO RADIO ITSELF (ALTHOUGH WOULD BE "CUT OFF" DURING TRANSMITTING), I HEAR AUDIO AS BEING RECEIVED THROUGH RADIO...WITH SPEAKERS CONNECTED TO BACK AUDIO OUT OF RB BACK PANEL, STILL HEAR SPEAKERS AS ABOVE BUT, NO RTTY/CW......IF AUDIO WAS BEING SENT, I SHOULD HEAR IT THROUGH MY "MONITOR RADIO".....
TO NOTE; THE FRONT MIC JACK OF THE ICOM 730 HAS A CABLE RUNNING TO THE BACK "MODULAR" INPUT ON THE BACK OF THE RB.....SEEMS TO ME THAT AUDIO WOULD HAVE TO COME FROM/THROUGH THAT MODULAR OUTPUT TO THE MIC INPUT OF THE ICOM AS A MIC WOULD DO IT....ALL THE INTERNAL JUMPERS ARE CORRECT AS I DID THEM ALL AGAIN THE OTHER DAY....THE BOARD IS LITTERED WITH "OTHER JUMPER BLOCKS"--- COULD BE AN ISSUE WITH ONE OF THEM NEEDING TO BE MOVED?
