I will have to  see if  Salisbury had  anything in   his  RRL files...:

>I  was reading about the radio proximity fuze that the U.S. developed in 
WWII  & was used to great effect in the Battle of Okinawa as well as in 
Europe.  As the fuze was an oscillator coupled to an antenna it radiated a low 
power CW  electromagnetic field in the 180-220 MHz range. What caught my 
attention was  U.S. concerns that these signals could be intercepted by the enemy 
& this  information used to develop countermeasures against the shells. As 
a  countermeasure, this source stated that the Navy transmitted spoof 
signals to  confuse any enemy radio intercept activity. Despite the fact that 
these fuzes  were declassified in 1970, I am not familiar with the equipment 
that might  have been used to generate these spoof signals. Any one have any 
insights to  this?
