Hi all. I recently bought the infamous Motorola GR300 Repeater. I have 2 GM300s in it. All is functioning normally, including the RICK. I am VERY familiar with all the ins and outs of these particular radios now after having read just about every page on repeater-builder, bat-labs, and a few others.
My problem is this:
I would like to interface my system (using the RICK) directly to my RPi to set up an AllStar node…
I have seen a lot of custom interface boards on the internet (RTCM, URI, RIM, etc), but has anybody ever seen or heard of someone interfacing their RPi directly to the Motorola RICK? I would think you could connect it via the J4-ACC pins on the Motorola RICK (similar to how this guy hooks up the ADS SR1 for courtesy tones in this video https://www.youtube.com/watch?v=EbCHXmQqeK0). The reason I want to do this is I would rather use what I have than buy even more hardware. Is it possible? The only thing I can see that’s viable right now is probably buying a single RIM-Maxtrac and running it into the RICK, but again, that’s just buying more hardware…
What do you guys think?
Any help or tips is very much appreciated.
