Hi,

? I'm new here, I've spent a few hours with a Raspberry Pi and a URDC II interface trying to set up an Igate/Digipeater.? Our local Igate has failed.? Getting to the point, I wanted to use YAAC with the raspberry pi URDC II interface combination.? Things were going along well until I came to the configure ports page of the set-up wizard.? Some help with this would be appreciated, its my hope that someone has already done this, but then maybe not as the URDC II uses the GPIO pins of the pi rather than a USB port.

YAAC does not have any TNC modem capability built into it; it expects you to provide some external implementation (in hardware or software). Given you're using a Raspberry Pi with UDRC-II, your best option would be to use DireWolf as your software TNC. As such, you wouldn't even need to use YAAC as a digipeater or I-gate, as DireWolf has that capability all by itself (and it would be more efficient at it too, because DireWolf isn't trying to update all the graphical screens YAAC has), although you could choose to not enable DireWolf's digipeating and I-gating capability and use YAAC to do so for the logging.

Even if you use DireWolf as a stand-alone digipeater and/or I-gate, you could still run YAAC and connect it to the KISS or AGWPE ports on the DireWolf process so you could watch what DireWolf was processing.

It would be nice to have the map and features of YAAC available. I had trying running Direwolf alone, but it wasn't apparent that anything was being decoded.? I could hear the local WX station in the TM-V71A audio but it wasn't showing up on aprs.fi? My own station was showing up on aprs.fi though.? It was getting pretty late and I set things aside to get some sleep.? I'd be happy to get the configuration right for Direwolf and at least get something working as an Igate for now, until the local one is back in service.? YAAC would be a big bonus in the (hopefully near) future.

If you run DireWolf from a terminal window, it should print out several lines of text describing each received packet as they come in. So, you need to confirm you're actually getting audio into the sound port you are listening to.

You might want to try installing a program called audacity. It's an audio editing package useful for musicians, theatre technicians, and others who process sound, but it's also a convenient way to ensure you're actually getting audio into your computer. Have it recording the input from the UDRC card and confirm that when you hear packets on the radio's speaker, you see the corresponding envelope growth on the Audacity oscilloscope graph. That way, you can confirm you're configuring DireWolf to listen and transmit on the correct audio port.

As for getting data to aprs.fi, that won't happen until you have an I-gate connection to the APRS-IS backbone with a valid passcode (so you're allowed to forward the packets to the APRS-IS). Either DireWolf or YAAC can do the I-gating function. You might want to join the DireWolf mailing list (direwolf@groups.io) or NW Digital Radio's udrc mailing list (udrc@nw-digital-radio.groups.io) to ask them for more information.

Just got back to the house, I have Audacity on the desktop, hadn't thought about looking for a Pi version.? Data is getting to aprs.fi as my station shows up with the correct SSID.? And you're right about joining the Direwolf group, the example conf files I'm finding have issues, for example I can't use "digi" for the SSID as it returns an error, and IBEACON gives me an unrecognized command error.? Thanks for the help, I'm off to join the Direwolf group.
In the future it may be a good idea to use YAAC with a Pi and a CM108 (modified) audio dongle, I'd like to use it portable or mobile for public service events.
