[OZAPRS] MFJ 1270C uidigi

It's been well over ten years since I touched uidigi, but I recall that you can connect a terminal program to seeing debug messages. It might also be that the MCU it's getting stuck in a loop and the watchdog timer kicks in and the MCU locks up.

I know that the MFJ-1270B TNC's don't have the issue with this, but I can't recall if there's an extra mod needed to be done with the MFJ-1270C

I'll dig though some old paperwork her and see if I have anything on the topic...

Hi brains trust,
I’ve got a MFJ 1270c running uidigi. After about a day of running it appears to go to sleep... the dcd light still indicates it is seeing data, but the tx side stops, eg tx indicator doesn’t light up on the tnc, A power down cycle fixes it and away it will go again for about 24hrs or so. While in sleep it doesn’t beacon it’s own position. It’s running on a stable power supply. Any suggestions ?
