Digirig Mobile with Yaesu 10pin DIN to FTM-500D using VaraFM

[KZ4JN]

I can pick up the audio from the radio and i’ve set VaraFM to the appropriate COM port (in my case SIX) but I am not able to get the Digirig to trigger the PTT when I have both cables (green/black) plugged in - what am I missing? Should I be able to trigger the PTT by “shorting” S to R2 on the black TRRS plug?

Yes, you should be able to simulate the hardware PTT from Digirig by shorting sleeve to nearest ring on Digirig’s black connector:

If radio doesn’t key up, please check the continuity in the cable.

I have the FTM-500 and I think your issue is likely a menu setting. I have a post in this thread that provides the radio menu settings to allow it to work with the DigiRig Mobile:

@VE7IIF

I have the same set-up as you, and have both Packet and VaraFM working correctly; both with the 1200 bps and 9600 bps DigiRig cables from the radio data jack to the DR Mobile, and on two separate FTM-500’s, so there’s hope

Here are the radio settings I’m using for you to compare, recognizing not every setting is relevant:

RX Menu #15 FM Bandwidth
Wide

Data Menu #69 COM Port:
Speed 9600
Output Packet
WP Format NMEA 9
WP Filter ALL

Data Menu #71 Data Speed
APRS 1200 bps
Data 1200 bps (I use 9600, but it’s cable dependent - most set-ups are 1200 bps)

Also, my Packet/VaraFM settings:

Yaesu FTM-500 DigiRig Mobile Winlink Express Settings (Click on images to enlarge)

For Packet Devices and MODEM settings in SoundModem by UZ7HO - PTT (COM) Port will vary per individual set-up: (I’ve changed the names in Windows settings to DigiRig TX et al for my own clarity, vs the Windows default of USB Audio Device)

Devices:

MODEM: (MODEM filters ch: B settings are not relevant)

And for Winlink Express using VARA FM:

Settings, VARA Set-up (FM System is WIDE for 9600 cable, Narrow for 1200 cable)

Sound Card (Drive Level varies based on volume settings in Windows Mixer)

PTT (Again COM port will vary per individual set-up)

VARA FM Winlink Session, Settings (MODEM Location must point to VARA FM install)

Any changes, or suggestions are welcomed.

Perhaps give it a try and see if you have similar settings that need to be changed.

Awesome! Hope is a great thing to have! I just went through and configured my WSJT-X just like Dennis did here: https://youtu.be/1EtrkyisCnc?t=117
I then took my digital multimeter and measured from pin 2(gnd) to pin 3 and it switches between open circuit and a much lower resistance (about 14 ohms) on the mini-DIN plug. The audio part of the Digirig seems to work fine (at least inbound to computer)
I just can’t seem to get it to trigger the PTT on the radio!? I even went as far as jumpering pin 2 to 3 on the connector which I understood to be the way to activate PTT but that didn’t work either..

I’ll give your settings a try.. I’ve never tried the “SoundModem” application before..
My install won’t let me save with sample rate of 11025, it says " TXSampleRate must be 44k-48khz! "?
