It’s kind of a long shot, but here goes: I’m looking for information,
especially the TM on the AN/ALR-3 radar warning receiver used on SP-2H
(P2V-7) aircraft. Xcvr is identified as 'R467/ALR'. The AN/ALR-3, an E/
J-Band ECM Receiver was used in conjunction with AN/ALR-8 equipment. I
have both the receiver and the associated control box C-1933/ALR and
have tested the device – I have 115V 400 Hz power – and am still
trying to think of an application for it!

Thanks,

John Mackesy
