If I am correct in the sound that you are hearing...it is probably the frequency and user identifier.

Yeah the beeping is a morse code transmission of the callsign of the licence holder, it's an FCC regulatory requirement

You won't hear them if you use the pl tones

Way back when, in the Bronx,we used to transmit once each hour the following message: "This is KED962, the radio station of the NY Fire Department, operating on an assigned frequency of 154.25 Mz. Dispatcher XX." Needless to say, we missed a few of these announcements as things got busy on a hot summer night.

i think these have to be transmitted at every half hour/hour due to FCC code but i could be wrong

We used to announce the call sign by voice but for the last 10 years or so it's been done automatically, every 30 minutes, in Morse code.
