[Milsurplus] AN/APR-4Y receiver MF wanted

[COURYHOUSE at aol.com]

Robert -  OK  thinking  back I seem to remember some of mine  have  the 
motor and some  do not.  It has been along time since I  played  with the 
dingle  unites ... they are under  glass in the  display...
 
 I do power up the   later Multi-band  plugin and   play  from time to time!
 
 
 
RE: difference between the AN/APR-1 plug-in's and the single-band ones for  
the APR-4(*) is that the former do not have the scan motor and limit  
switches.

Ed,

The two AN/APR-4 receivers run off of 115 VAC  60-1000 cps.  The APR-4Y 
only runs off of 400-1000 cps.

Besides  the nomenclature, the difference between the AN/APR-1 plug-in's 
and the  single-band ones for the APR-4(*) is that the former do not have the 
scann  motor and limit switches.

Jeff- what is the difference between  apr-4 and  apr-4y?
We have a ECM  display here at  SMECC Museum  
of  Jammers and  Receivers. 
( and  yea always looking  for more  too and  all the manuals etc)

for the  APR-4 you can use all the   single plus ins  or there is a  
wonder plug in of later vintage what is MULTI-BAND ( many of these were  
made 
quite late compared to the  old  single band plug  ins.  

I have  found all the plugins to interchange between  the APR-1 and APR4

Hello All!

Been looking for an AN/APR-4Y  receiver mainframe to complete a setup. 
Anyone have one they are tired  of?

Also still looking for WWII jammer stuff, have a lot of  it, but you might 
have a better one for my collection. Working on getting  permanent space 
here at the college for a small museum of WWII  Electrotechnology.

Thanks &73
