AC-Powered Intercom 2-Way Personal Radio - 14 Channels (single)

Catalog # 21-1845

RS FRS 21-1845.jpg

This is an A/C powered wireless intercom using the FRS portion of FRS/GMRS radio frequencies.

Setting Channel Frequencies and CTCSS

On the station bottom, you will find two arrays of dip switch. These switches are used to set the channel frequency, and CTCSS code.

Radio Shack calls it Quiet, or QUIET code and what they are referring to is Tone Encoded Squelch (CTCSS or PL Tone). This prevents radio interference from coming though your radio (breaking squelch) unless the radio signal is accompanied by the correct sub audible tone. This is not a scrambling technology, it does not give your conversation any greater privacy against other people listening in with a radio receiver, it just helps keep other radio activity on the frequency from coming through your radio so that you are able to monitor with less noise and interference.
