Heath CA-1

[Glen Zook]

I am "sorta" looking for a Heath model CA-1.  This is
the "Automatic" Conelrad Monitor manfactured during
the late 1950s into the 1960s for use by amateur radio
operators.

Back during that period of time, every amateur had to
continuously monitor a broadcast station.  If a
Conelrad alert was issued, the broadcast station would
go off the air and everyone was instructed to "tune to
640 or 1240 on your radio dial for more instructions".
 That is why there are the little "CD" emblems at 640
and 1240 KHz on the dials of many AM broadcast radios
made during the 1950s and into the 1960s.

You either had to have some sort of "automatic" alarm
attached to a radio or else have it turned down to a
level that you could hear the station but the audio
wouldn't be picked up by your microphone if you were
working "phone".

The CA-1 hooked to a tube-type AM broadcast receiver
and when the station to which the radio was tuned went
off the air, the CA-1 removed the AC from the
transmitter and turned on a red light.

Anyway, it depends on what someone wants for one of
these.  I would rather trade if possible since I am
still fighting with Hartford Insurance Company over
long-term disability benefits!
