Serial Communications Interface Input line.
SSI to and from the GCAP II IC CODEC used to transfer transmit and
receive audio data.
A full-duplex (receiver/transmitter) asynchronous serial interface.
See Serial Communication Interface Input Line.
How the microcontroller communicates to modules and ICs through the
CLOCK and DATA lines.
An electrically transmitted electromagnetic wave.
An operating mode in which the radio is muted, but still continues to
analyze receive data to determine RX signal type.
See software potentiometer.
Computer programs, procedures, rules, documentation, and data
pertaining to the operation of a system.
A computer-adjustable electronic attenuator.
Frequency range within which radiation has specific characteristics.
See Serial Peripheral Interface.
Muting of audio circuits when received signal levels fall below a pre-
determined value. With carrier squelch, all channel activity that exceeds
the radio's preset squelch level can be heard.
