Default Scanner Beeps

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.

Each channel needs to be set for EDACS. For example, channel 101 should have an "ED" behind it - 101ED.

Also, the bank that your EDACS channels are in should be set for EDACS. Easier to Read Pro-97/2055 Scanner Manual (shortcut to programming trunking systems)

This link, Easier to Read Pro-97/2055 Scanner Manual will be your best resource for programming your PRO-97.

Default 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.

She'll get used to it, just keep the scanner on. Mine finally did after about 3 years. I don't even think she notices when the scanner is running, just another noise in the house.
