[Milsurplus] IP-69A/ALA-2

[Mike Hanz]

Designed to work with the APR-1, -4, 4Y, etc. or any search Rx with a 
30MHz IF.  It's simply a panadapter, as opposed to being a component of 
a large "ALA-2" system.  Predecessor was the APA-38, which is 
essentially identical functionally but has 1940's metal tubes rather 
than the ALA-2's miniature ones.  
http://aafradio.org/countermeasures/surveillance_bay.htm has a bit more 
on the -38 if you're interested.
