op25 (police radio)

Post by studysession » Fri Oct 19, 2018 9:43 pm

Question about op25 -
Taken me couple of weeks to come this far. I believe I have the trunk.tsv & mycity.tsv file configured correctly. Anything I find online says I need to adjust the -q setting to get things working. I can never get the line over the peak of the frequency. Any help would be appreciated as I have tried many positive and negative numbers and not moved that line at all.

In the photos you you can see the syntax I have and what has been showing on my screen. I keep switching between the RTL-SDR & HackRF to see if there is anything different. Same result regardless which one I use.

It's been a few months since i used my op25, but from memory, there are keys (poss. the arrow keys) that allow for live fine tuning. Have you tried those in conjunction with the phase plot?
