Re: No TX audio on JS8CALL


 

开云体育

Thanks for the response.

I’m using CAT control and everything there works. ?In fact, I can hit TUNE on JS8CALL, radio goes into transmit, and will modulate my voice from the speaker mic.

It’s really weird. ?I can use the monitor function on ic-7000 and hear the tune tone and the JS8 worble… so really, the audio is making it into the ic-7000, and out the speaker somehow! ?But it’s not modulating the SSB.?

The manual p 116 says make the data signal 0.4Vp-p and I’ve verified with my oscilloscope.

Time to take the radio apart!!!!
…. actually, before that, I’m going to hook up a function generator to the data in, and see what happens.?

The problem is probably that your software isn't telling the IC-7000 to go into XMIT mode.

Check the settings in JS8CALL, see how it is doing XMIT / RCV switching, and check that whatever it does on the DATA port matches what the IC-7000 expects.? I'm pretty sure there _is_ a "PTT" line in both the 6-pin and 13-pin DATA jacks.

Unfortunately, Icom didn't put a "digital VOX" capability into the IC-7000.

The tune button on JS8CALL software also does not cause modulation (radio does go to TX, controlled by CAT)

Ahh -- if the JS8CALL "Tune" button puts the IC-7000 into XMIT mode, but there's no power output from the rig:

. . . Check that you're using the correct pin on the DATA jack -- I think it's called "MOD" (modulator input),
. . . and that you're in USB mode,?
. . . and, if there's a menu item that switches between MIC and DATA, that it's set to DATA.
