using a SignaLink USB with VarAC

I have an old TS-430S Kenwood, that still works great. I use a SignaLink USB and have worked various modes like WSJT-X and the two work well together.

In trying to setup VarAC with the SignaLink USB I can't get the 430S to transmit. I am not using any transmtting keying mode except what the SignaLink sends to the 430's mic input, from its command from software I am using, in this case VarAC.

In the PTT Configuation for VarAC what should I set it up as, since I use the SignaLink?

I looked in the VarAC manual and read comments ( problems & corrections ) here from others using a SignaLink , but it does not address my problem.

Again, any ideas why no keying from VarAC to 430S via SignaLink, as I said it works OK when using WSJT-X modes.

Vox on your software settings to key the Signalink. Signalink should generate the PTT to your rig. I am using both signalink and digirig on some older radios as well.

I was trying to find a manual for a Signalink but didnt see any on their page, but from the looks of it the only keying is VOX or VOX generated. So on VarAC it should be Vox/None

Thanks Gary,

I'll try that. That means I'll need to put my 430S into VOX mode too, odd that working WSJT-X mode this was not an issue, using VOX mode.

I realize that all software is different.

I have the SignaLink manual and they mention VOX mode should be turned OFF on the rig your using ???

Again I'll try it and see what happens.

Looking at the manual it looks like the VOX is in the Signlink and that VOX circuit them keys the PTT line to the radio, assuming that is the way the cable is wired. If that is the case the settings in irrelevent, but would set it to None/Vox.
