Running gqrx led me a different error number - I'm using 1000 now. No change. Am I missing something? I've tried gain 0, gain 3, 30, gain 40, no change.

gqrx

mattames commented 5 years ago

What type of dongle is it? If the offset keeps changing then it is probably thermal drift in the XO.

Cheers, Matt

That site has 700mhz freqs too so youre going to need two rtl dongles to be able to hear all the voice traffic.

Your center freq for the 800mhz channels looks good, although centered would be 852.3625

If you are using a rtl sdr the max rate you can use without problems is 2.4mhz, not 8mhz as you have set.

Looks like trunk-recorder is setting the sample rate to 1.024mhz cause the 8mhz is incorrect, then its setting the center freq to ~857.02mhz which is out of the range of your control channel at 853.475 when using the fallback 1.024mhz rate.

I would set the center to 852.3625mhz, set rate to 2.4mhz. If you are using a decent rtl sdr your freq error should be no more than +/- 1000hz or so.

"center": 852362500, "rate": 2400000,

The signal strength on gqrx doesnt look that high either, in my experience trunk-recorder needs a fairly good SNR to decode.

Which sdr are you using?

rpdale commented 5 years ago

Thanks all. Using RTL-SDR v3. I edited the center and rate to no avail. I swapped out for a NooElec R820T, ran gqrx to find the new error, and ran it again with the same outcome.

Using these dongles I can hear the system fairly well (not perfect) running Unitrunker on Windows but I am in a basement - I'll move the setup outside later today where I have a clear shot to the tower and see if that changes anything.

I'm showing the output of Unitrunker on the Windows 10 box that is sitting right next to my RPI. All I did was unplug the RTLSDRv3 from the RPI and plug it in to Windows. Should I change any settings?

unitrunker signal

For the fun of it, I installed op25 on this RPI4. Audio sounds weird, but it appears to be tracking it just fine?

./rx.py --args 'rtl' -N 'LNA:47' -S 2400000 -f 853.4750e6 -o 25000 -q -2 -T trunk.tsv -V -2 -U 2> stderr.2 op25

The only thing could think of changing is the error, try -1875

Also - maybe try fsk4 for the modulation instead.

robotastic is the winner :) fsk4 worked. Here are a few files:
