Kenwood TM-V71 & DIgirig for Win10 APRS?

,
1

I have a Kenwood TM-V71 working with a Digirig for VARA FM on Win10 using the MiniDin6 9600 cable. What would I need to use the TM-V71 & Digirig to RX/TX APRS? A software TNC, I presume…

Would there be any instructions/videos to get me up and running?

I have had success with APRSIS32, YAAC on Win 11.

"SoundModem by UZ7HO"will work for that. It will allow you to run Winlink and via a packet session too if the VARA stations go quiet.

Currently using same cable and can interchange the Kenwood TM-V71, TM710G, Icom IC-208, an IC-207 or Yaesu FT-8800 without the computer blinking or hiccupping. Very stable setup once it’s setup.

I’m going to experiment setting up 2 Digirigs/cable setups from the same computer to different radios. Hoping that allows me to use Winlink via one radio and keep PinPointAPRS running off another radio simultaneously. I’ll need to configure the ports a bit so there isn’t any conflicts but we’ll see…

I use Direwolf and the 9600 cable. It works fine.
I use APRSIS32 as well.

I am having trouble Tx/Rx with this setup:
TM-V71A with 144.390 on the digital VFO of the radio
Digirig (RS232) via Digirig V71A cable and Digirig USB C cable
Soundmodem
PinPoint APRS
Windows 10

Strangely, I can keep the same configuration and move over to a Baofeng UV-5R and have no problems Tx/Rx.

That sounds frustrating. You probably already checked squelch and simplex. There is a guide, Troubleshooting Digital Modes – digirig which will give you a step-by-step approach.

Thanks, Constrainted.
I verified the Kenwood - Digirig by transmitting back and forth with a secondary system that I have here.

I reduced the Squelch. I can successfully Tx/Rx between this setup and my secondary unit just fine, now.

I have a digipeater less than a mile away that I can access and send APRS packets with HT with a rubber duckie.

The Kenwood setup is not repeated by the digipeater, for some reason. The Kenwood did transmit (verified via secondary HT APRS setup and another HT just for audio monitoring).

Again, the kenwood transmits, but is not digipeated.
Progress, but still stumped.

OK, you have an excellent setup for troubleshooting. I would vary the TX timing in soundmodem for the TM-V71, to see if that makes a difference. I would also vary the TX power, and see if that makes a difference.

Thanks again, Constrainted.
I was just looking over my settings and thought the same thing about timing.

Ugh, it was so tricky getting soundmodem timed to work with the HT.
I’ll setup a secondary Soundmodem dedicated to the Kenwood so that I don’t lose my HT settings and give it all a go. Thanks again.

I agree. Good approach. Let us know what you find.

Ya nailed it.
I adjusted squelch to barely on and set Soundmodem’s Tx Delay to 750msec (3x’s that of the HT’s settings).

We got through!! Thank you, thank you.
Best 73 and goodnight.
