[Boatanchors] [Milsurplus] WWII, Germany and Their 170 KC C.D. Net

[Glen Zook]

The 1945 edition of the ARRL Radio Amateur's Handbook has an entire chapter on carrier current.  There are plans for a transmitter using a single 6L6 and another using a pair of 802 tubes.  Also, there are plans for a modulator, a transceiver, and a receiving converter to use with an HF superheterodyne receiver.

I just wonder if operating carrier current would get into those baby monitors that use the AC lines for transmissions!

    Maybe not relevant to this but remember that the band 
around 170 khz was used for broadcasting in Europe and I 
think still is.  Germany had a megawatt station at Munich on 
by memory 173 khz. This station was maintained by the U.S. 
for a time after the war. I am pretty sure I've seen details 
on the web but must don't have time to search right now
