Radio Service
Software DOS-based software containing the feature set of a radio. See also
CPS.
random access
memory A type of computer memory that can be accessed randomly; that is, any
byte of memory can be accessed without touching the preceding bytes.
RAM See random access memory.
read-only memory A type of computer memory on which data has been prerecorded. Once
data has been written onto a ROM chip, it cannot be removed and can
only be read.
receiver Electronic device that amplifies RF signals. A receiver separates the
audio signal from the RF carrier, amplifies it, and converts it back to the
original sound waves.
registers Short-term data-storage circuits within the microcontroller unit or
programmable logic IC.
repeater Remote transmit/receive facility that re-transmits received signals in
order to improve communications range and coverage (conventional
operation).
repeater/talkaround A conventional radio feature that permits communication through a
receive/transmit facility, which re-transmits received signals in order to
improve communication range and coverage.
request to send A handshaking signal (used in communication links, especially RS232)
to indicate that data is ready for transmission. See also clear to send.
RESET Reset line: an input to the microcontroller that restarts execution.
RF See radio frequency.
RF PA See radio frequency power amplifier.
ROM See read-only memory.
RPCIC Regulator/power control IC.
RPT/TA See repeater/talkaround.
RS232 A common interface standard for data communication equipment.
RSS See Radio Service Software.
RTS See request to send.
RX Receive.
RX DATA Recovered digital data line.
SAP See Serial Audio CODEC Port.
