Your logfile reports that op25 does not see your Airspy device.     This may be as a result of a virtualization problem with your Ubuntu VM.     Run another lsusb and see if the Airspy device still

shows up or not.    If it does, then I would be suspect that the airspy library did not initiate properly during the installation phase.  BTW,  you don’t need the -2 in your rx.py command line because your county is running a Phase-I system.  Of course, that is not the issue at this point in time.       

 

I am willing to help you over the phone if you want some help and want to install TeamViewer on your PC so that I can access your VM remotely to take a look at a few things.

Well, it's a busy workweek, so I've been slow to reply back.  But thanks for all the suggestions.  The control channel changed today, so I cleared out everything in stderr.2 first and then ran this:

 

../rx.py --args 'airspy' -S 3000000 -N 'LNA:15,MIX:15,IF:15' -f 769.80625e6 -t -q 0 -2 -w -U 2> stderr.2

 

and got this:

 



 

Then I looked in stderr.2 and found this:

 

..

 

But if I do the same thing with 'airspymini' instead, I get this:

 



 

And stderr.2 has all this in it:

Trunktracker,

 

>From what I can fine the Airspy Mini gets configured the same as the Airspy R2 with

the exception being the sample rate differences.

 

I further assume from an earlier posting that your installed the op25/boatbod version that

supports starting rx.py without a trunk.tsv file using just the -t option.   This was a handy

feature that allows you to discover the P25 system’s NAC, SID, and other information needed to properly

construct your trunk.tsv file.    

 

As has already been suggested, do post your stderr.2 logfile..   OP25 will create and write to the logfile

(stderr.2) each time you execute the  rx.py command line with the 2> stderr..2 option specified.  The

Information contained in that logfile should prove useful to diagnose what is happening.

 

Bill, WA8WG
