[R-390] The OLE receiver sensitivity test revisited

[rbethman]

I have an HP-3336B Frequency Synthesizer.  It has an output down to 
-72.99 dBm.  I've got an attenuator from an old GR-1001A that will be 
attached to the output.  So I'll be able to take the 56.167 µV rms 
output, and throttle it down significantly.

I've one SS Kenwood R-200, and have gotten it to where it was not 
connected to my AN/URM-25, separated by 2 - 3 ft., and had a solid 
signal with no antenna attached.  It was only picking up the sig gens 
leakage.

I'm not overly fond of the R-2000.  It has loads of birdies.  It does in 
a pinch, and can be muted through the accessory jack on the rear panel.

I'm going to perform an alignment on my Northern Radio SP-600.  I'm 
going for the highest sensitivity I can get with it.  (I'm still stuck 
with waiting for decent weather before I can finish the front panel of 
the R-390A that's on the bench.  Then I'll finally get it up and going.
