Yes John.

I just need to figure out why your UHF Machine works without port forwarding and you need to give me the IP address of the existing machine so the new one can reference it.

There is nothing in my netgear NightHawk router mentioning either UDRC. Do I need to add something?

Hi Anna,

I noticed several recent GitHub updates. Am I missing something obvious or are there still some things to be worked out?

When I start MMDVM-UDRC it appears ok…

Followed by this in MMDVM-UDRC:

This is on a working DStarRepeater system with the dstarrepeaterd service disabled.

I’m just fooling around with it in my spare time out of curiosity. I don’t have a real need for it otherwise.

I’ll admit I don’t understand the Pseudo TTY part very well.

Because I’m trying to get my repeater up and running again, and would like to use MMDVM-UDRC to do so, I’ve been doing some work on getting MMDVM-UDRC to work. My code is in the nwdigitalradio github account at:

https://github.com/nwdigitalradio/MMDVM-UDRC

You’re welcome to play with it with the understanding that it’s development code, may not work at all. I’m getting close to having things possibly working acceptably.

An issue you’ll have to deal with is that mmdvm-udrc expects a 24000 sample rate. The UDRC hardware doesn’t support this and if you try to use hw:CARD=udrc,DEV=0 it will fail complaining on not being able to send sample rate. You might try using plughw:CARD=udrc,DEV=0 instead. I’m using a custom asound.conf to support it.

More as I get things worked out.
