Re: Wireshark not capturing everything
Hi, I hadn't messed with this for a while, but I decided to re-install OP25 tonight because someone suggested that maybe the error correction had not installed properly. The re-install went smooth, but the Wireshark results are the same. In addition I notice that if I modulate (speak into the P25 radio mic) I get some errors in Wireshark as well as in the terminal window that WS is running (with a silent carrier I don't get the errors). Below are the errors. This confuses me because when I run OP25 without the Wireshark switch and in the mode where it decodes audio it sounds perfect. 22:21:13 Warn Dissector bug, protocol P25 CAI, in packet 408: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 461: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 463: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 464: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 465: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 468: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:14 Warn Dissector bug, protocol P25 CAI, in packet 471: packet-p25cai.c:1453: failed assertion "state != -1" 22:21:15 Warn Dissector bug, protocol P25 CAI, in packet 509: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:15 Warn Dissector bug, protocol P25 CAI, in packet 513: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:15 Warn Dissector bug, protocol P25 CAI, in packet 514: packet-p25cai.c:1453: failed assertion "state != -1" 22:21:15 Warn Dissector bug, protocol P25 CAI, in packet 515: column-utils.c:482: failed assertion "!ep_verify_pointer(str)" 22:21:15 Warn Dissector bug, protocol P25 CAI, in packet 516: column-ut Thanks.
Hi, Is op25.osmocom.org <http://op25.osmocom.org/> <http://op25.osmocom.net/>down? I have not been able to get to the site for a few days, however the main osmocom.org <http://osmocom.org/> still works for me. thanks, Joe

This has happened before, the last time they mentioned it on the GnuRadio group or some other. Someone or something hosed their server and it took a couple weeks to be brought back up. Dom

Hi All, Does anyone have scope.py and other pages from the OP25 website saved? Since the site is down I cannot access the command args, examples, and instructions. I just purchased an B200 USRP and would like to get up and running. mtindor and Scott are assisting at Radio Reference also, but the OP25 stuff would be helpful. thanks!
I'm also looking for command args, examples, and instructions. Thanks Don

Hi Don, Happy new year too! So far I am still learning the ropes with the B200. It’s doing a good job on an LSM system that is around 20 miles away. Still working out some of the tweaks though. I wish it had filtering though - but I guess I can buy some bad pass filters. Joe

Hi all, I have a neat idea. Can OP25 be modified to “repeat" an entire spectrum say 851.0125 to 853.9875 with low power so a digital scanner in proximity to the repeater can receive the signal. Specifically can OP25 be able to receive CQPSK (LSM) and convert to C4FM in real time - since scanners have no issues with that modulation. thanks! Joe
