RR is actually useful, heh. Been running it for over a year.... It takes some setup, but having a phase 2 'scanner' for the cost of an SDR... love it. There's also people putting it on Raspberry Pi 3.... Making it portable. Install Ubuntu Open terminal window Code: cd ~ git clone https://github.com/boatbod/op25 cd op25 ./install.sh Then you'll need to set up text files for your systems.... defining system freq and NAC Here's SS911 as test... Code: "Sysname" "Control Channel List" "Offset" "NAC" "Modulation" "TGID Tags File" "Whitelist" "Blacklist" "Center Frequency" "SS911 Site 1" "774.68125, 774.43125, 773.93125" "0" "0x1E1" "C4FM" "ss911t.tsv" "" "40108,40119,40113,40204,30204,40209,40210,40217,40246" "SS911 Site 2" "774.48125, 773.98125, 770.60625, 770.35625" "0" "0X1E2" "CQPSK" "ss911t.tsv" "" "40108,40119,40113,40204,30204,40209,40210,40217,40246" "SS911 Site 3" "773.73125" "0" "0X1E3" "CQPSK" "ss911t.tsv" "" "40108,40119,40113,40204,30204,40209,40210,40217,40246" "SS911 Site 4" "774.70625, 773.20625, 774.20625" "0" "0X1E4" "CQPSK" "ss911t.tsv" "" "40108,40119,40113,40204,30204,40209,40210,40217,40246" "SS911 Site 5" "773.48125,772.93125" "0" "0X1E5" "CQPSK" "ss911t.tsv" "" Tab delineated file. Then run a lengthy command Code: cd /op25/op25/gr-op25_repeater/apps/ ./rx.py --args -rtl=0 -N LNA:46 -f 772.13125e6 -S 2048000 -V -q 0 -T psrs.tsv -2 -U and you're set! There are other options for using a web interface as well... Attachment: op25.jpg

Could you make a short video of it decoding an IWN VHF site? Whichever site is strongest for you... just curious as to what it looks like. I have an extra laptop laying around so I may give OP25 a shot. |
