G4 - Normal Trunking Talkgroup Scan

[sibbley]

I'm have a bit of an issue with a talkgroup that is NOT programmed getting through during Normal Trunking Talkgroup Scan. It is an encrypted talkgroup, so you can imagine how annoying this can be.

I was reading about the wildcard 65535 and this made me wonder. The system I am listening to uses patched supergroups in the 65xxx area. If by chance, this particular 65535 supergroup is used, could that open the radio to receive talkgroups that are NOT programmed for normal talkgroup scan?

When this happens, and I start hearing the encrypted tgid, I can only reprogram the radio to get rid of the offending tgid.

Is there a way to set the G4 to not receive the patched supergroups? Or can the radio be set to mute encrypted transmissions.

If you have a TG programmed in normally, and its part of the patched TG, then it will pass all the audio of the other TG that are patched.

If one of the other patched TG has encryption unfortunately your out of luck as the TG you have programmed in is part of the patched group.

Example.
If you are monitoring TG 5.
System has TG 2, 5 and 8.
TG 8 has encryption.
Because 5 is a TG you have programmed in, and is now part of the patch, you will get any audio from TG 8 as well.

The "new" TG you are seeing is what the system is showing as the patched TG. Its temporary and when the patch is gone the new TG is gone as well.

Is this a Harris system by any chance?

Or can the radio be set to mute encrypted transmissions.

The pager is capable of having encryption codes loaded, so an option to mute encryption would be in conflict.

Yes, It is a Harris System. You're explanation makes sense. The patched talk groups are used for fire and ems dispatches, I'm taking it from you're explanation that these patches are system wide which is why I would be seeing the encrypted PD talk group.

I'm guessing this is normal for a Harris system? It's my first Harris system.
