External PTT doesnt allow PC digitial Audio through to TX

Keith Richards

v1.4 is awesome ! Digital TX audio = no more wires via ACC = no RFI which is cool  ).

However seems I cant get the digital PC TX audio setting to drive rig to actual modulation if I use external PTT to key the radio. If I click MOX with mouse works it works just fine? Am I doing something **** ?  The level meter is going up and down like a good un. Also no MON audio output for the PC TX audio setting.

I've been told I'm **** many times before so this could be the actual problem.

Is this behaviour because the majority of operators will be using the PC TX audio setting to work remote.  I like to site in front of mine (6300) so I can keep a beady eye on it .  Will this be supported later maybe ?

Also while I'm on,  I've noticed another phenomenon  - on immediately keying the radio I get some kind of short noise burst (ACC and  PC settings for approx about 30ms) which generates enough TX modulation to send several watts of RF energy to my linear resulting in a 400 + pep output before I start to talk - some people RXing have made comment on the noise fairly routinely.

I think this is already under investigation though looking at other posts wrt buffer filling up ?   

Best Regards

I have a similar problem with a lack of transmit audio not coming through. Receive audio is fine, space bar toggles t/r. DAX control panel shows no transmit audio, tune button shows rf, level meter shows no audio, but I can hear audio in the Heil headset. I feel like I am missing one switch somewhere? Bill, KI4B

I am also now getting a message of a DAX driver error. Bill ,KI4B

Sounds like you need to open a HelpDesk ticket so we can eliminate the reported issues first and then work from there.

Some of the use cases for digital transmit involve alternating between SSB and digital data.  SSTV would be one case, users of software like EasyPAL would be another.  To accommodate this style of operation, the "hard PTT" lines will draw audio from microphones while software and MOX will work with the digital data.  This way you can use software to key and transmit and then pick up the microphone and talk without continually changing the mic input settings.  It was reasoned that most that are using digital modes will transmit with CAT or the API directly and that this would help the folks that switch inputs and not cause an issue for the "pure digital" operators.
