MARKER -BEACON RCVR
The first all- transistor electronic
marker -beacon receiver for
commercial and military aircraft
has been developed by RCA. It
operates on only 3/4 of a watt, and
widths of 500 KC or 100 KC may
be made from the front panel by
means of a selector switch. The
narrow bandwidth i -f is primarily
intended for a reception of PWM/
FM and PTM /FM signals with a
nominal deviation of ±50 KC.
