Jeff,

Well, it depends upon the vintage of the AN list. But my point was merely 
that the AN/APN-2 is functionally neither a radar nor an altimeter. It does 
not listen for a reflection of its own signal, but for a signal generated by 
the Beacon (transponder) on a different frequency. There is a caution in the 
AN/PPN-1A manual against setting the transmitter and the receiver to the 
same frequency. I have never read the complete AN/APN-2 manual but somewhere, 
it probably says the same thing.
