Hi,

I'm new to scanning, I picked up a PSR-310, so far no complaints. I live in Los Angeles and when listening to the County Sheriff dept, I'm dealing with a unique (to me) radio system, from RadioReference.com:

The Sheriff's Communications Center (SCC) is located in East Los Angeles near the Biscaluze Jail, and dispatchers all incidents countywide. To assist SCC in confirming who is transmitting, each time a deputy presses the transmit button on his radio the radio transmits a unique identifier (called a "G-Star AID", "burp", or "burst" encoder, or more commonly a "turkey call"). The unique IDs are displayed on the SCC dispatcher's screen. When a radio's emergency trigger (also called "E-Trigger" or man down switch.) is activated, the radio switches to the emergency channel and transmits the Radio ID five times.

Each sheriff's station has a Dispatch channel and a Local Tactical ('L-TAC') channel, each of which may be permanently shared with one or more other stations depending on the volume of station radio activity. Nearly all incidents and communications begin on a Dispatch channel (and then could switch to L-TAC / A-TAC / C-TAC or STAR-TAC).

NOTE: Mobile traffic is not rebroadcasted over the output frequency of the dispatch channels. Instead, only a beeping tone is broadcast to signify to the field units that someone is talking. To monitor units in the field you must program in the input frequencies also. The corresponding L-TAC channel is included in brackets.

My question is, is there any way to have the radio resume scanning once the "beeping tone" begins after dispatch has completed voice transmission on the same frequency? In other words, have the radio detect that the frequency is transmitting beeps and not voice.

I've already programmed the L-TAC channels with priority over the dispatch frequencies this works, but just thought I'd ask the experts in this forum to see if I was missing something.

Thanks!
