[R-390] AN/URM-25s

[rbethman]

This may be so.

I will only explain that with my AN/URM-25D on, not connected, and about 
3feet away from a closed Kenwood R-2000 with nothing connected to the 
SO-239, and NO cable on the AN/URM-25D, I was able to pick up carrier 
and S-Meter deflection.  This was with the output dialed to the minimum 
on the Sig Gen.

So the leakage is real.  Both were on separate circuits, and both had a 
separate ground.

Hence my commentary and my intent.

If I want to begin "sniffing", I have an HP-312A Frequency Selective 
Voltmeter.

However, based on the described above observation, I'm going with the 
extra RF seal!
