Re: Repeater controller decode packet radio on repeater input?

 

Hi Tadd,

Ok, I understand.? Adding a wart on the side of the existing controller might cause more trouble than its worth.? We already had the Raspberry Pi in place, and an easy spot to tap into the receive audio.? Because we use PL decoding in the Arcom controller, the receiver itself runs with the squelch open.? That means that we have no issue with the un-squelch delay clipping the front end off the packet, something that makes decoding the packets problematic.? It's something to consider.? But adding that Raspberry Pi for Echolink / AllStar support was an interesting exercise in itself, with challenges in breaking ground loops and various sources of some pretty nasty audio hum.? We also considered tapping into the RF coming into the receiver (between the receiver and the cans) and using Direwolf with an SDR dongle, but this was easier.? Perhaps the RF-tap / SDR approach might work better for you, though you'd still need a computer of some sort.

Good luck!? And Yaesu, if you're listening, please fix your user interface on these rigs!

Greg, ?that is pretty close. ?I am hoping somebody will integrate the feature into the controller, with or without Direwolf.
I pondered using a separate Raspberry PI and Direwolf, and letting the Direwolf see the receiver audio and then use text to speech and a GPIO to tell the repeater controller that COR is present. ?Now I need to add an audio switch so open squelch noise doesn’t get into the controller, etc etc. ? ?I think it would be easier in the controller software in the first place.

Somebody will add this feature, maybe. ?My Yaesu FTM500 is really easy to screw up to send APRS on a repeater. ? I have done it once in a year, but fortunately it was my 440 repeater haha.

I don’t have Internet control. ?While I do have packet capability, the site owner would want to run the frequency numbers on my new transmitter, and I don’t want get into that for this purpose and I don’t want to get caught adding a transmitter without going through the process.

We’ll see if anybody picks this up as an attractive value-add to repeater controller software. ? Right now I’m using an NHRC-5 controller but if somebody had this feature I might have to hook up a Raspberry PI based controller just for that feature. ?Even if it isn’t a big problem on my repeater, the locals would stand for a demo and might ponder moving the 2m repeaters to whatever solution adds the feature.
