Hi All, Just trying to set up my system (finally!) after various starts and stops along the way. I have a few of the generic USB FOBS, and I have them modified and all seems to be well there... I have a system I did a fresh install of EVB on, and all seems fine there. The radio is a GE Delta on 2m. It decodes DTMF fine. I can't, for the life of me, manage to get TX Audio to work properly. If I use txtone or txvoice in 'radio tune', I either get very weird behavior (sputtering sound on my receiving HT) or a dead carrier. However, if I plug the USB keyfob into my laptop (Mac OS X) and feed audio into it and then manually ground the PTT line the GE Delta is happy to transmit that audio and it sounds great. So I can (maybe) assume that the FOB is working fine, and my wiring is correct. I have run the svn update routine, so I should have all the latest bits and bobs, and I do not see any error messages along the way, so I'm really at a loss as to what to try next. Any thoughts?
