cant remember if i heard beeps. i have to get the channel again, i reprogrammed the scanner so i cleared it. but yes i hear only the dispatch. it was in the 100mhz range.....im looking now
I know here in my area I can only hear the medical helicopter talking to the hospital. I have never heard the hospital respond to the helicopter. And I've never heard any beeps from the helicopter.
I personally am not that technical, but I know that a while ago LAPD used GE MPA's and you could only hear the dispatcher talking, but no body in the field unless the dispatcher pressed a button.
