Lost modulation (audio) on FT8

Stephen Dubin All Messages By This Member #42108 Perhaps this may be related to a prevous thread (or maybe not). I have recently been migrating to Lnux OS and been very pleased to find WJTX and FLDIGI for Linux. At first, both programs seemed to work quite nicely with my IC7000 and SignaLink. Settings are PTT = VOX and Radio = none. Same setp also worked nicely (and continues to do so) with my Elecraft K3. However, now I have a problem with IC7000, but not with K3 -- so I think it has to be something on Radio. WJTX and FLDIGI look like they are working OK -- FT8? waterfall and callsign signals are decoded OK. When I hit "tune" button, SignaLink and rig think they are energized (red TX lights go on on both SignaLink and IC7000), but no modulation. There is a short blip on ALC and then zero. I have checked mic gain, power and VOX and they seem OK. Only intervening event I can recall was one episode on 6 meter SSB selected from mic keys. FT8 and PSK31 frequencies on IC7000? are from memories. As mentioned, switching to K3 with same SignaLink and program/computer works fine. Is there some change in IC7000 settings that would still exert VOX (PTT) but lose modulation? TNX for help and toleration of what must be a dumb mistake.

Glenn Jensen All Messages By This Member #42109 开云体育 Hi Stephen, I run Linux as well (Mint 21 or Ubuntu 22.04) with my IC 7K / ; you must be very careful about checking your mixer settings, because sometimes for whatever reason, they change (i.e. using another application).? I use a startup script to force the correct audio device selections, and to fire up all the applications that I use (I also have a kill script to ensure these apps are killed off if for some reason I get a hung system).? I have a separate USB Cable for CIV, and the RigBlaster keys the rig. ? To make my life a bit easier, I set up a few uDev rules to map my devices to easy-to-remember names (I have two Yaesu HF Rigs, and I would bet things mixed up without these rules).? ? In my configuration, I’m using the rear panel connection (ACC Socket) rather than VOX (and I use WSJTX or JTDX, coupled with FLrig, Grid Tracker / CQRlog (with Gridtracker pointing to my CloudLog instance). ? 73’蝉, ? Glenn, WA6BJQ p.s. - happy to share my scripts (and welcome any feedback / corrections) ?
