APX Scan Issue

Postby fallspolice » Thu Jan 16, 2014 1:25 pm

I have several APX7000 radios that I am having the same issue with. I have the radios set up to scan a trunking system while parked on a conventional channel. When a transmission is made on the trunking system I watch the radio jump to the particular trunking TG, but there is no audio. When the transmission is over, it goes right back to the conventional channel. To make this even more complicated, this issue only appears to occur on 3600 systems. With 9600 systems, I hear all of the audio when it jumps to the TG with activity. Any ideas on how I can fix this? It has to be something in the CPS.

Thanks in advance for any suggestions!

Is it a smartzone or smartnet system? If it's smartnet and you have the coverage set to smartzone it will do what you describe. Another thing to check would be if it's an analog channel and the voice is set for digital.

I have found a similiar issue with regards to the TX Inhibit and Scan on a 3600 SZ system. Usually when I scan I and I'm out and about I set my radio to TX Inhibit so there is no accidental PTT on the parked TG. If I for some reason change tg's and the radio remains in scan, with TX Inhibit engaged, I only get 1/2 of the conversation if it is dispatcher and field unit taking from that point forward. Once I reaffiliate with the new TG, by disabling TX INhibit, it goes back to normal.

I have discovered this issue with both the APX and XTS2500 that I carry.

Thanks for your reply! It is a smartzone system and is set for that. Also, it is digital and set for that as well.

Thanks for your reply as well! I switched the TX inhibit on and off and it still did the same thing. I even powered the radio down in between switching.

Yes it is really a weird thing. Not that it is a big deal as my field users do not have the capability and I know about it.
