I recently acquired a Radio Shack PRO-97 scanner. Works well but a bear to program.

Question: When listening to the Melbourne, FL area police/fire, at the end of each transmission there is a series of beeps. I don't mind but it's driving my wife NUTS!!

Any help/ideas?

What you are hearing is likely a data protocol known as MDC1200. It is often used to send the radio/unit ID over the radio at the beginning or end of transmissions. Dispatchers will see this info so they know who the transmissions come from.

Often, those MDC1200 tones are sent from the radio without a CTCSS tone, so if your radio will support that sort of tone squelching, you may be able to block it out.

just being picky

edacs tones are not ctcss tones.
edacs tones come into play at the end of transmission
ctcss tones are from end to end of transmission, its how the radio unmutes.
