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

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.
