Re: Signal Identification Help

I believe that those are SCADA signals. They send data from all kinds of monitoring devices from storm water to gas etc. Quite prominant in a number of bands with good signals. They almost always are proprietary for the purpose and difficult to decode.

Re: op25 (police radio)

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?
