Definition
Alinement of incoming data bits with internal clocks.
Signals that are buffered by the audio power supply to isolate the
COMSEC signals in the audio/data section.
The RF frequency to which the RT is tuned and onto which the
information signal is modulated.
To strip a signal of data speed or frequency hopping control
information, leaving only the information signal, and collapse it
down to its original signal speed.
Insert data speed or frequency hopping control information into
a signal by creating gaps in the information flow and inserting the
control data into the gaps. The process will increase a signal’s
data speed.
The lowest power signal the RT can receive.
Signals in the audio/data section of the RT that may contain
COMSEC coding.
Feedback of the operator’s voice into the handset receiver
when transmitting.
150 Hz tone accompanying received signals, necessary to
