For my Odroid XU4 I landed on this by googling and finding a fairly old article. PTT /dev/ttyUSB0 RTS DTR Also I seem to recall it working with the DTR and RTS reversed on a different platform. In

Guess found the solution PTT /dev/ttyUSB0 RTS DTR seems to work John

I just tried all options PTT /dev/ttyUSB0 -RTS/RTS/DTR/-DTR they all resulted in that the transceiver went into transmit as soon as I start up direwolf John

I am indeed running GPSD. But it already occurred when I didn't have GPSD in my direwolf.conf. At this moment my config is: ADEVICE? plughw:2,0 MYCALL NOCALL GPSD TBEACON EVERY=4 symbol="igate"

Hello John, This should work fine. What are you configuring in your direwolf.conf for your serial port device and desired signal? Are you using the common default signal of the "RTS" signal? In

Am building an APRS Digipeater/Tracker for mobile use. Have an EasyDigi with the USB-to-Serial for the PTT. Have tried to use this but as soon as I have configured the serial port the transceiver goes

50/50 chance it had NOTHING to do wit the EasyDigi. Been using homebrew sound card interfaces for over 20 years and never killed a computer.. I did plug a 13 pin Kenwood connector into a Icom once,

Jim, back in 2019 I fried the motherboard of my laptop when I was switching radios TM V-71a to FT-891. At that moment I was using a USB soundcard and all I did was switch USB printer able from radio

Direwolf 1.7 Snapshot A works well on Windows with my DRA-65 audio adapter and "PTT CM108" in direwolf.conf. VOX is disabled (by jumper) in the DRA-65.

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
