key to exit. The Roger Beep should only be used when conversation is difficult, and it is hard to tell
when each transmission is over. Most operators find listening to a Roger Beep extremely annoying.
Excessive use of a Roger Beep (by continually keying the PTT repeatedly) could exceed the tone
limitations imposed on the CBRS operational requirements. Do not use Roger Beep with other tone
functions.
UHF CITIZEN BAND RADIO SERVICE (CBRS)
Channels 1-80 UHF CB TX/RX Simplex (direct CB to CB transmit and receive)
Duplexed (repeater access) Channels 1-8 and 41-48 have been allocated to memory position 81-88 and
91-98 and alpha tagged (channel name labelled) as channels REP 01-08 and REP 41-48 (REP for repeater).
REPEATER OPERATION
Duplexing allows access to repeaters in the UHF CB Band for increased transmit coverage in some areas
where these repeaters exist. Only use these channels for extending your communications range when you
know the channel of the repeater facility in your local area. It is recommended that you do not use channels
31 to 38 and 71 to 78 Simplex in areas of specific repeaters as it can cause interference, as these are
repeater input channels. The FOP Pro has these channels alpha tagged with an asterisk as a reminder.
Channels 5/35 (alpha tagged E) are the emergency channels and are monitored by volunteers in some areas.
Do not use these channels in non-emergency cases.
Duplex Channels have been alpha tagged REP. Repeater input channels are tagged with an asterisk .
Channel 11 is the customary calling channel (alpha tagged C) and channel 40 is the highway channel (alpha
tagged H).
Note: No voice transmissions are permitted on data channels 22 and 23. Equipment meeting this standard
will inhibit voice operations on channels 22 and 23. Channels 61, 62 & 63 are for future use, and TX
