Re: No TX audio on JS8CALL
|
Thanks Carl….
more questions / advice (before you tear the rig apart) ? - have you ever been able to work digital modes with your 7K (or any rig)?
- do you have anything other than the Unitek Y-247A?
- are you intimately familiar with Linux?
- Make sure that pulseaudio has not switched out your ports (see picture below – from HamPi)
- Get PSK (on FLDigi) or FT8 on WSJTX/JTDX working first
? Should be electrically isolated from the rig…. Best practices

My configuration (with the 7K) works just fine, feeding it with a .? In my case, I also have a separate USB CAT cable (because I use this on Ubuntu and macOS in addition to Win10 (RIGblaster virtualizes the USB to provide the audio interface and CAT from a single USB connection (only on Win10)).?
73’蝉,
Glenn ? ? ? ? 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.? ?

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.
