[Milsurplus] Y YJ 1945 ?

[Hubert Miller]

I had thought "long-wave radar" had been dropped once the inception of
microwave radar. But i was looking at a radio chart for the Pacific area,
August 1945,

and i see many locations still have the UHF radar beacons YH, YJ  ( page 83
of following link ) listed. For example, Canton Island has YG and YH
equipment. 

The wonderful site that describes Navy ( and Army SCR-nomenclatured ) radar
and beacon equipment, and shows locations in aircraft too,

-application.html

 

I had previously asked here, in some wartime account i had read, where radar
beacons were set up in jungle to guide attacking aircraft, what equipment
that was.

After looking at the above link site, i conclude it would have to be:
AN/PPN-1  ( interrogated by AN/APN-2 ); the only manpack portable racon (
radar beacon ).

Listed as a 30 lb. pack; altho that must have been largely the battery pack,
as i remember it only weighing around 8 lbs. including antenna. I had one,
and set it up

in my forested backyard in Washington state for some photographs. I'll post
the photos sometime if the film has not faded or color shifted. This set
went to Steve

B.  I learned that the PPN-1 is quite a collector item due to association
with D-Day airdrops.
