OP25 Updating question

[boatbod]

Yes, the TSBK counter continues to increment. The only visual indication is that the program will tune to a talkgroup, and then will fail to move on, it doesn't appear that it is returning to the control channel. The last talkgroup and alias will just remain.

I'm not sure if I have the latest build or not. Last time I tried to update, it "failed" possibly because I modified some file.

I'm using a single Airspy Mini.

I have attached the stderr.2 file.

Since you are using a single airspy mini with 6Mhz available bandwidth, you have two choices how to set it up:

1. Make the device tunable ('tunable': true) in devices section of config file. This would allow the device to tune around as needed, but is only good for a single voice receiver. It is a very quick fix to get you working, but longer term if you want multiple receivers to share the single sdr hardware you'd need option 2.

2. Find the mid-point frequency of the P25 system you are attempting to monitor, and park the airspy there. In the devices section of the config file, set 'frequency': xxxxxxxxx to whatever freq you came up with.

To make sure you have the latest version of op25, git into the directory structure and issue a "git status" command to see what files have been locally modified. Save copies of them. Next, blow away the changes by issuing a "git checkout ." command followed by "git pull". If that all worked, you should now have the latest code.

Option number 1 above works. (tunable=true)

Option 2: If I set the "set frequency" to a frequency that is halfway between the lowest and highest frequency in the system (midpoint is 855.700), it never locks onto the control channel (852.100). It just keeps rotating through the control channel list, but it never stops on it. Option 2 only works if set to tunable=true. Which seems satisfactory to me.

Option 2 is only going to work if the range of the lowest to highest frequency lies within usable range of the dongle. i.e. 85% of 6Mhz = 5.1Mhz.
