3 years ago One thing that jumps out at me is
[bpd.csv] Started with Control Channel: 7.742188e+02
Try changing your config file from
"control_channels": [774.21875],
to
"control_channels": [774218750],
like the rest of your frequency references.

3 years ago it was "control_channels": [77421875.0],
looks like all of the example config files have the wrong values!?
Is this error ok? Or am I missing something else?
[2020-10-21 10:41:11.005829] (error) [ebrcstest] Control Channel Message Decode Rate: 1/sec, count: 3looks like all of the example config files have the wrong values!?
Which example config files are you looking at? All of the config file examples in the trunk-recorder/examples directory have frequencies written as Hz values. Or do you mean that the actual values used in the sample config files don't work for you?
Yes, the Control Channel Message Decode Rate: 1/sec, count: 3 message is a problem. The control channel specified in your may be incorrect or you may not be receiving it well enough to reliably decide it. Double check that you're specifying the correct frequency for the control channel . Your comment value of 77421875.0 is 77.421875 MHz but based on the other parameters in your config file I'm guessing you want 774.21875 MHz which is 774218750.0. Also you try adjusting your gains and antenna placement if you think you should be able to receive that system.

3 years ago @mathisono Checking back it see if you got things working and if you spotted some specific errors in the example folder.

3 years ago Antenna gain setting and signal reception isn't the problem here!!!!
I'm rather confused, all of the example config files don't work and something here is crashing my hack rf???

3 years ago The example code is just an example. you will have to customize it for your local system.
Try running hackrf_info to make sure the HackRF is working.
In your config file, the rate is set at 90mhz, the HackRF maxes out at 20mhz. I think 8mhz is a standard config. I would give that a try. 8000000

On the HackRF, it will have severe drift unless he obtains a TXCO module for it. It'll result in no-decode issues.
The other portion is the bandwidth the HackRF uses against TR. Most systems do not need more than 10MHz (1000000), for the ones that do, 12.5MHz (12500000) of spectrum coverages does the job. For me, I'm just lazy and set it to 15000000 (15MHz). :)

Could someone shed some light on why im getting : (error) Unable to setup a System to record, exiting...
