P25 Missed Calls Issue

[CDTbolt10033]

Hello,

Before the changes to P25 stuff were done everything was working fine however when the new changes were committed to the nightly, It missed P25 calls every once in a while (odd times) and my trunking recorder sometimes showed an empty source and source label (From RID, and From Alias) So far the latest nightly has been more stable than previous versions and does not crash like previous versions did which is great but the problem with the P25 missing some calls is forcing me to go to a version before the P25 changes were made.

I should mention that the previous version 0.6.0 worked fine but was notoriously unreliable due to it crashing because of no available Java memory. The P25 calls would come in fine and would be full conversations and not partial with any missing calls.

I'm jumping in with the same report.

I was running version 0.6.1 Beta 1 with SDRPlay RSP1A. I decided to try my new RSP1B (metal case upgrade). Sdrtrunk didn't recognize the tuner. So I installed the latest API from SDRPlay. SDR trunk still did not recognize the tuner, and now it wouldn't even recognize the RSP1A tuner. So, I downloaded the nightly build, and it works and picks up both tuners, but now many voice calls show fade and then disappear. I've rebooted the system and tried both of my tuners and messed with my gain settings to no avail.

To add more info, I noticed in the stuff in the event log that is on the program is doing some weird stuff where if there is a group call it will repeat it a bunch or if there is a patch / or not it will show a patch on a talkgroup to itself so 1000, 1000 patched which is weird since its patching to itself.

What kind of system is yours? Mine is L3H P25 phase 2 with phase 1 control channel. I'm noticing it is actually very consistent. All traffic on the paging talkgroup and patch talkgroups is working. I'm not even registering voice calls on operational TG (although it does register data calls and registrations on the same). Non-emcrypted law enforcement TG always show fade.

Motorola P25, Phase 1 CC and Phase 2 talkgroups I think.

Well got my problem fuxed. Uninstalled sdrplay api, then installed downgraded version if 3.14. Use the most recent sdrtrunk release not nightly and it works fine

When these changes were committed, I started having problems:
https://github.com/DSheirer/sdrtrunk/commit/7e709d9d6f38d99bcefdff726380b0fe77245e9f

P25 Trunking Phase 1 CC with Phase 2 talkgroups and for DMR, Capacity Max Tier III Trunking.

I've been experiencing some odd behaviour with the latest version of the software. It's been missing group calls and after running for a while (a few days to a week), it starts displaying anomalies such as duplicating entries in the event log table on the GUI. Version 0.6.0 worked fine and handled all calls, but the latest nightly build doesn't catch all calls and seems to miss some for unknown reasons. While this nightly version is more stable than V 0.6.1 and doesn't crash, it's not functioning properly with P25 and DMR. I've observed that on Trunking Recorder, some group calls don't display an RID or alias and are blank on P25, and DMR has the same issue. The missing alias and RID issue only occurs after about 5 to 12 or more group calls. Currently, I've switched back to using V 0.6.0 to ensure I can hear all calls without missing any, unlike with the nightly version.

I'm missing 98% of my calls on sdrtrunk, I see them come through but they don't stream and I don't hear anything. Ice gone back to 0.6.0 and 0.6.0 beta 1 and nightly, it's showing my system has only had 6 calls in the last 24 hours. It's usually 12000+ calls in 24 hours
