[R-390] Scored a Sherwood SE-3 Sync detector

[John Gedde]

I scored a vintage Sherwood Se-3 synchronous detector.  I aligned the front
end of the Sherwood along with the 5 kHz notch filter and here's the result.

 

Paired with my R-390 it's unbeatable.  The Sherwood pulls AM audio out of
the mud remarkably.  It also functions as a selectable sideband synchronous
detector by offset tuning.  Lastly, she functions as a product detector for
SSB.

 

I took a video of my R-390 using the Sherwood SE-3 with the R-390 tuned to
All India Radio in English on 9455 kHz.  You can view it here:

O really weak AM signals, the Sherwood means the difference between readable
audio and not!  I'll take more videos of it handling SSB as long as weak SSB
signals
