And v1.7 does work fine with the various DRA models, I have been testing it the past few days. It should also work fine with any of the other C-Media based devices that use the audio chip GPIO pins

John WB2OSZ has released Direwolf 1.7 Snapshot A which includes a Windows binary that includes native CM108/119 PTT support on Windows. Give that a try with your Master Communications device:

And really beating a dead horse now, attached are some audio samples of on-air packets. The first several are with TXD set to 250ms, the last several are set to a ridiculous 900ms. You can easily hear

And when I assemble DRA-65 and 70's, one of the tests I do is jumper for VOX mode, set up for packet operation, and connect to the local RMS gateway. My default TXD is 250ms and they work fine with

Thank you. will look for that

Hello Rodney, Which version of Direwolf? Should be v1.6 Not sure what you mean about "serial cable". You need an "audio" cable to be connected to the RA35 sound device Ok. Following random YouTube

Since there is a message in your startup screen shot that says "... Note: PTT not configured for channel 0. (Ignore this if using VOX). ..." I'd say you are either NOT using VOX, or your VOX is not

My understanding is NOT backward at all.Remember the original post is about VOX, not HARDWARE PTT control.? With VOX, the actual radio PTT line CANNOT be asserted until there is audio for the VOX to

Robert, Your understanding of TXD is backwards. TXD starts when PTT is set. During the TXD time flag characters are sent which gets the receive modem in sync. When TXD ends the data frame is sent. We

The subject and requested information for this thread was Masters Communications VOX. So you agree that using VOX in the DRA-65 or DRA-70 isn't worth talking about and the only thing to talk about on

As an alternative under Windows, use the CAT7200 utility and ComOcom to have Direwolf use RTS to drive the C-media GPIO PTT. See _CM108_PTT_control.pdf in the FILES section. FYI. Links to: Inexpensive

Direwolf CAN drive PTT from the GPIO3 output of the CMedia CM119A, however indirectly: CAT7200 is a program that uses the RTS (or DTR) signal from a virtual COM port to drive GPIO3. ComOCom is a

How the app uses TXD with PTT has no impact on? this discussion - the discussion is about VOX which doesn't use the PTT control line directly through the app. So let me ask two DIRECT questions that

But, if as indicated above, Direwolf DOES send the same audio on both channels at the same time, this is not an optimum configuration for PTT.? The PTT needs to go active BEFORE the audio.? I was

And by the way, the DRA series that have VOX are jumper selectable to choose which channel the VOX circuit gets audio from. The advantage to using separate channels is that you can adjust the VOX

Just to clarify, if direwolf.conf selects a stereo output device (using ADEVICE, ADEVICE0, ADEVICE1 or ADEVICE2) followed by ACHANNELS 1, Direwolf on Windows will output the same audio to both left

I am just trying to directly answer the questions in the original post: ============================================================================ John Kristian Mar 11 ? #4999?? Will Direwolf on

or you use PTT from Direwolf to turn on an audio circuit (such as a 555 oscillator) to create a false audio into the vox circuit. On the other hand, you would be building more stuff to make this work
