reciter
The reciter is a module of a TB8100 base station that acts as
receiver and exciter.
reverse tone burst
Reverse tone bursts can be used with CTCSS. When reverse
tone bursts are enabled, the phase of the generated tones is
reversed for a number of cycles just before transmission ceases. If
the receiver is configured for reverse tone burst, it responds by
closing its gate.
RSSI
RSSI (Received Signal Strength Indicator) is a level in dBm or
volts that indicates the strength of the received signal.
Run mode
Run mode is the normal operating mode of the base station.
