 - and - the official CONELRAD frequencies were 640 & 1240 kcs.

A POPULAR ELECTRONICS of the period had plans for building your own 
monitor - essentially a carrier monitor, it "read" the AGC / AVC voltage, 
and if that dropped, it was obvious you'd lost the station.

I used the same trick in Kansas City, back in the early 70's for monitoring 
6m propagation.  I had a beater TV (you could barely see the pic) it was 
tuned to Channel 2, which was about 125 miles away in St. Joseph, MO (KC had 
NO Channel 2 - good thing).  Attached to my Telrex 4-element "tee-matched" 
beam, it watched for Channel 2.  If the signal strength began to climb up, 
eventually this would turn on a darlington-pair amp, which triggered a 
relay, which turned on a bell in the kitchen - shazam, I'd run upstairs - 
hook up the Clegg Venus, and ALWAYS worked the openings, when other guys 
wondered how I knew.

CONELRAD - answer to the Red Menace.
