Re: aprs <--> trbo with [crossband] voice

Programmed up the xpr4300 today, connected via usb cable to pi. Successfully sent/received txt messages from xpr6550, with pi connected to aprs-is.

Next step is to rig up interface from pi to tracker3-mini for aprs-rf link.

Re: aprs <--> trbo with [crossband] voice

KD8EYF TRBO-NET software is written in perl, and quite well laid out for further expansion. It has the capability of parsing incoming text messages from the DMR radio - can currently then execute internal commands (cmd), lookup last known location of a callsign (who) or send aprs messages (aprs). Mi...

Re: XTS3000 Alignment

Apparently if the battery is getting low, rather than still transmitting, like most other motorola radios I've encountered, it'll just sit there and blink the status light. Won't transmit analog either. Dropped it on the charger, and it worked... for a bit. Apparently the batteries I got with the ra...

XTS3000 Alignment

Anyone have experience aligning a xts3000? I've got two of them that don't want to push out p25 at 144.590. I could trial & error adjust it all day, but could use some pointers.

I'm guessing the same procedure would fix up the two astro spectras I've got as well.
