It's not from database, just channel i've found myself. At the first time there were no frequencies, after hitting the wizard button and choose 'standart' (the other options gave similar results) the frequencies appeared, all of them around 860mh.
If you went in something and choose standard, that sounds like the band plan wizard.
Why? one dongle listen to control channel, and the other follow the voice channel wherever it is. why there's a limit?.
Yes, there is a limit. The standard rtl sdr dongle only covers about 2.5MHz. The freqs shown in your first pic span 15MHz. You can not cover that span with 1 rtl dongle. And now you have different freqs shown in your last pic.
The way unitrunker works is, after you set up your signal and voice vco's, you need to supply it with a control channel. It does not do that automatically. If you have a radio reference subscription, you can have unitrunker download the system . But otherwise, you need to supply the control channel, and tell unitrunker what it is, like motorola, provoice, apco p25 etc. Otherwise it wont work properly.
I don't know what is going on with this channel, so i attach screenshots of ANOTHER channel. Again, nothing works.
It would really help if you listed your city and state. Then we could try to look up what you might be hearing. I could be wrong, but I have never seen an 800MHz system using a VHf freq as a park channel.
