RE: [op25-dev] Recent changes

Matt. I don’t think this works with Graham’s op25 (rx.py) fork having tried a number of configurations (combinations) but not able to decode conventional P25 non-trunked IMBE. Perhaps Graham or Max can elaborate if this functionality is still supported. Thanks again!

Here's a few exmaple commands I have used with my USRPs (via UHD) and airspy:- ../rx.py -S 2500000 -o 50000 -q 2 -f 434075000 --args 'uhd' -D fsk4 -P fft --gains 'PGA:10' ../rx.py -S 1000000 -o 50000 -q 39 -f 434075000 --args 'uhd' --gains 'PGA:40' ../rx.py -S 2500000 -o 50000 -q 2 -f 438187500 --args 'airspy' -D fsk4 -P fft --gains 'MIX:5' /rx.py -S 1000000 -o 50000 -q 2 -f 438187500 --args 'uhd' -D fsk4 -P fft --gains 'PGA:30' Cheers, Matt On 19 December 2017 at 09:06, 'William Becks' wa8wg(a)centurytel.net [op25-dev] <op25-dev(a)yahoogroups.com> wrote: OK. How does one setup the rx.py command line and/or trunk.tsv file if required to monitor conventional traffic? Can you please post example configuration?

In fact this feature was there before trunking was.

Especially for the recent coding changes allowing for FQDN --wireshark-host command line entry. The addition of the --nocrypt function was very innovative and solved an issue in my area where some talkgroups use a mix of clear, and encrypted transmissions that were previously impossible to reject without also filtering the clear voice transmissions as well.. I am personally very grateful for the work that you and Max have done to improve the code. If I could wish for one new feature, it would be to incorporate code allowing rx.py to monitor conventional IMBE non-trunked transmissions. Such a feature would be great for monitoring small non-trunked systems in addition to providing a great resource to monitor and analyze amateur P25 transmissions from MMDVM and similar devices. Keep up the good work and best of holiday greetings!

Earlier changes include the addition of the source radio id (where available) to the terminal screen, as well as indication of when encryption is active (only applies when using --nocrypt command line option).
