Hi all,

I've managed to find and overcome just about every issue to get to this point. Right now, I am monitoring a P25 Phase I system in Northwestern Indiana with a single RTL-SDR dongle, running on a dedicated Ubuntu 18.04x machine. I've gotten everything compiled to date (tried it first with 17x, then 16x, then 20x, and finally found that 18x worked). Hoping I can get some help on this one. Thank you in advance!

Here is my config.json file:

{ "sources": [{ "center": 770200000, "rate": 2148000, "ppm": 69.0, "gain": 35.0, "digitalLevels": 3, "digitalRecorders": 4, "driver": "osmosdr", "device": "rtl=00000001,buflen=65536", "modulation": "fsk4" }], "systems": [{ "control_channels": [771568750,771556250,771293750], "type": "p25", "shortName": "Indiana SAFE-T (Porter)", "broadcastifyApiKey": "XXXXXXXXX", "broadcastifySystemId": "XXX", "audioArchive": false, "talkgroupsFile": "chanlist.csv" }], "broadcastifyCallsServer": "https://api.broadcastify.com/call-upload", "controlWarnRate": 5, "callTimeout": 0.75, "frequencyFormat": "mhz" }

However, when I run ./recorder it spits out the following, and then hangs until I open a new term and sudo kill the process:

Also, I am trying to scan the Indiana SAFE-T Hoosier P25 system, specifically the Porter County system.

I figured out the solution to my problem in two parts: 1) My center frequency was set too low. I took all of my control frequencies, subtracted the lowest frequency from the highest frequency, halved that number (to find the center between the two). That ended up bringing my SDR within range of the control frequencies. 2) I had to set an error rate. This took some playing around. I'm still not sure how temperature will affect frequency drift, but I'll find out in a couple days.

I'm posting my config.json file for the benefit of those who are also having similar problems:
