Re: aprs <--> trbo with [crossband] voice
Over the air programming can be done with the gen2 trbo radios (xpr7..., xpr5..., sl series). Nothing fancy available for the first gen radios.

Re: aprs <--> trbo with [crossband] voice
The ARS / GPS reporting stuff seems to work while scanning -- set the channel selector to an ARS channel, then hit scan. Monitor everything in the scanlist whilst maintaining GPS reporting.

Re: aprs <--> trbo with [crossband] voice
ARS-E daemon status page (program behind the TRBO interface) -- http://qth.kc9uhi.net:14680/ The Gen1 TRBO radios, in my experience, don't have the best GPS sensitivity. Way worse than the byonics GPS that works under a metal pot in my basement. Sitting on a window ledge typically results in a GPS f...

Re: aprs <--> trbo with [crossband] voice
Hooked things up in the vehicle. Had serial communication issues between the pi and tracker3. New DMR repeater in GB caused major project shift. Programmed up for TimeSlot 2. Now: XPR4300 interfaced to pi, connected to internet. Made some modifications to the TRBO-NET software to support some additi...

Re: aprs <--> trbo with [crossband] voice
Project Update:
Apparently connecting the COR and PTT lines between Motorola/Icom radios doesn't work. Need to rig up a transistor circuit.

Re: aprs <--> trbo with [crossband] voice
When a MotoTRBO radio is connected to a computer via USB, it creates a network interface on the computer, and assigns an IP via DHCP (typically 192.168.10.2, unless the radio IP is changed in its codeplug). Information received over-the-air by the radio is forwarded to the computer over said network...

Re: aprs <--> trbo with [crossband] voice
Minor setback. Went to build the audio interface cable, and the accessory jack on the xpr4300 uses a different metal contact than the maxtrac connector. Ordered, waiting for those to come in.

Re: aprs <--> trbo with [crossband] voice
Fixed the GPS conversion. Travel was being mapped opposite of actual movement. The software was reading the GPS data as an unsigned int, whereas the data was actually a signed int. Signed int is encoded using two's complement binary, which is pretty much opposite of unsigned int. Thus, the opposite ...

Re: aprs <--> trbo with [crossband] voice
Had issues with the GPS conversion formula in the TRBO-NET software. Latitude was spot on, but Longitude was way off. Was calculating out to somewhere in western wisconsin. Took the average value of several GPS posits from the raw data stream (somewhat mapped out in the source code) and calculated a...
