It's probably the channel number to frequency lookup area. I see this system is re banded. I know I have have to edit it before for part of my system. I am moble now but the code is in smartnet_parser.cc
Hmmm. I suppose that should become an option when configuring a SmartNet system.
Thanks for the pointer!
Would it be as simple as changing smartnet_parser.cc:25 from:
freq = float(cmd * 0.025 + 851.0125 - 10.9875);
to:
freq = float(cmd * 0.0125 + 851.0125 - 10.9875);
?
I guess I'll just have to find out.
This was absolutely the issue. TYVM.
Awesome! Thanks @dreinhold I keep meaning to put together a Wiki article on all of this. SmartNet doesn't always follow a standard channel plan and needs tweaking.
I'm using trunk-recorder on OS X Sierra. I'm using it with an Airspy. I'm using it to listen to the King County (WA) Pubilc Safety trunking system, which is a Motorola SmartNet system.
I am successfully decoding the control channel, I can see calls starting and stopping.
It is also creating wav and json files in the expected place, but none of the WAV files actually contain anything (I once -- ONCE -- got a WAV file that had a transmission in it).
I am unsure what to do except to start exploring the code and adding debug stuff to it.
Any ideas what to look at first?
