Yaesu FTM-150 + DigiRig Mobile - APRS TX not being decoded / Winlink won't connect

Hi everyone,

I’m hoping someone has this exact combination working.

My setup:

  • Yaesu FTM-150
  • DigiRig Mobile with the official FTM-150 cable (rear 10-pin DATA port)
  • Windows 11
  • Dire Wolf + PinPoint APRS
  • Winlink Express + SoundModem

Here’s what’s confusing:

  • I receive APRS perfectly.
  • Dire Wolf decodes nearby stations without any issues.
  • The radio keys normally and the RF power meter shows output.
  • I can hear my packet burst on another receiver.
  • PinPoint is connected to Dire Wolf over KISS.
  • Winlink sends connection requests, but every RMS ends with “Disconnect Reported.”
  • APRS packets only appear on aprs.fi when they’re sent over TCP/IP. No RF iGate seems to hear my transmitted packets.

Current radio settings:

  • DATA BAND: B-BAND FIX
  • DATA SPEED: 1200
  • 144.390 on the B band for APRS
  • 145.610 on the B band for Winlink testing
  • High power
  • No tones

I’ve spent most of today troubleshooting and feel like I’m down to one small issue. Has anyone here successfully used an FTM-150 with a DigiRig Mobile for APRS or Winlink? If so, I’d really appreciate seeing your Dire Wolf, SoundModem, or radio DATA settings.

Thanks!
