'wa8wg' wa8wg@centurytel.net [op25-dev] op25-dev at yahoogroups.comDisregard my previous message. I had to reinitialize the SDR and rx.py now loads with a zero center frequency in trunk.tsv using the lower sample rate as suggested. Bill William G.

I tried setting the center frequency to zero in my trunk.tsv and turning the sampling rate down but rx.py doesn’t like the zero center frequency. See below. Where can I download the patched version that allows a zero center frequency statement? pi at raspberrypi:~/op25/op25/gr-op25_repeater/apps $ ./rx.sh linux; GNU C++ version 4.9.1; Boost_105500; UHD_003.007.003-0-unknown setting gain lna to 49 set_center_freq: 0 ./rx.sh: line 2: $'\r': command not found ./rx.sh: line 3: $'\r': command not found ./rx.sh: line 4: $'\r': command not found ./rx.sh: line 5: $'\r': command not found ./rx.sh: line 6: $'\r': command not found ./rx.sh: line 7: $'\r': command not found ./rx.sh: line 8: $'\r': command not found ./rx.sh: line 9: $'\r': command not found ./rx.sh: line 10: $'\r': command not found ./rx.sh: line 11: $'\r': command not found pi at raspberrypi:~/op25/op25/gr-op25_repeater/apps $ Thank you, Bill William G.

If so then OP25 remains tuned to the center frequency and if not, it retunes the SDR each time a frequency change is needed. From what I've seen the slow sample rate (250,000) on the PI causes the changes to be somewhat slow, so I was getting the first word(s) of calls chopped off. Currently (for the PI) we recommend -S 1000000 and setting the center frequency to zero, or omitting it. Another user reported getting a crash with this, and a possible workaround for it has just been pushed to the repo.... It should be possible to set the center frequency to zero. When this is done the trunk-tracking mode should work fine no matter how wide the system is, but it does preclude the use of the log-all-talkgroups-to-disk mode, unfortunately...
