[Milsurplus] Unknown ADF Receiver

[Bruce Gentry]

That is a surprise to me, and may have applied only to airborne 
installations. When these were used in control towers or GCA vans, all 
the manuals and equipment registers called them a Wilcox 807 in 1970-73. 
Also,  our ILS marker beacon transmitters and their manuals  had only 
commercial numbers, no GRN- or GRT- numbers at all.  I  think there was 
a fair amount of equipment that  never had an AN/ number or the number 
was obscure and no one bothered with it on the logs.  Bruce KA2IVY
