CC drops, lockups on TDMA

[relicwr]

So the Motorola Phase 1 in my county comes in clear as bell, but I do notice the control channel will drop out. It seems to happen very often but comes right back. Before I got a G5, I would use DSD+ and it's getting traffic at all times that the receiver isn't. Granted there's a 1 second delay from the talkgroup release, but it will sit idle while DSD is getting normal traffic and it'll take it a few seconds to pickup anything after releasing (even if the control channel doesn't drop out).

Another issue is with a county above me that has 2 sites and has mixed TDMA/FDMA talkgroups. This is a Harris system and it hops TGs pretty quickly. Has anyone else ever had issues where the radio stops responding for over a minute on TDMA talkgroups? The radio will be stuck and I can't do anything until it fixes itself. Turning it off and on does nothing as well as the system is technically still running.

I have this same issue with my G5 running a Harris system as well. Most times it works fine but often it will “hang” on a TG after a transmission for a few minutes. Sometimes I can switch knob positions over to a conventional scan frequency and it will “reset” itself and I can go back to trunking it works fine. It’s annoying to say the least but I have no clue why it does it. If you figure out anything let me know and I’ll do the same.

I made a thread about this happening to me on the Michigan Phase 1 system some years back. There were several replies but nothing ever really worked for me except rolling back to a very old firmware. I will try and find it and post it for you to read.

Found it: Posts #32 and #33 seem to be the closest reason as to why this happens.

G4 Random Reception Dropouts

Hi All, Had my G4 a couple of weeks now and on occasion (seems to be more frequent lately) it will lose signal reception after a transmission is received. I can hear the entire transmission and then the signal meter drops to nothing. During this time I miss any radio traffic until the signal...
