THE MONITONE
A VERY FUNCTIONAL ACCESSORY!
I ran across an article in a 1950s QST for a CW monitor and decided to
incorporate it into a station monitor
to use with one of my boatanchor stations. The MONITONE is the result;
it incorporates RX/TX switching,
CW/AM monitoring, receiver muting, and an SWR bridge. The oscillator
uses an NE-51 lamp in a relaxation
circuit with variable tone. The unit is now mated up with my 75A-4
and HX-50 and makes operating much
more enjoyable.
