[Milsurplus] E. H. Scottr RCH or SLR-F?

[Al Parker]

Hi folks,
    I'm looking for some info on the subject item, I've done a google &
found quite a bit, but still not sure which model it is, does anyone know
the differences?  It's "vintage military" I guess, as they were used as
"morale" rcvrs on shipboard in WW-2.  Here's the rambling story of my find
at the DurHamFest (NC):
    Sat. I got an E. H. Scott either RCH or SLR-F, not sure which.
The front panel tag was gone.  In working condx, tho' very dirty.  The
seller said he had it fired up last Thurs. & no hum, sigs on all bands
exc. just noise on VLF (with very little ant.).  It's mil construction,
very good, might not need much more than cleaning.  Same freq.s as the
BC-779/SP-210LX, VLF, no BC band, ~2-23mc.  I hope to find out
what the dif . is betw. RCH & SLR-F  - they seem to be the same, but must
be something dif.  I've seen pix showing the front label in 2 dif places,
but they've called both an RCH.   Both models have the same freq. coverage
& overall specs, from what I can find.  I got the RCH manual from BAMA,
but nil on the SLR-F manual yet.  I"ve seen some differences in the IF can
construction and the covers, in the pix I've seen.  It does not have a
cabinet, which apparently was another 40 lbs or so, well shielded for
minimum radiation, as was the worry back then.
    I got it in from the van yesterday & did some cleanup on it, put a
heater under it to dry it out well before I fire it up, it's probably been
sitting a long time in the humidity around hr, and even tho' the seller
said it "worked fine," he/we may have been lucky that he didn't leave it
on long.  It's certainly not a communications rcvr, but with it's wide IF
should be a good broadcast listener, even with a single-ended output.
Similar setup to the BC-779/SP-210LX - I had one of them that I re-did abt
2 yrs ago, then sold it 'cuz I found another nice one to work on.
    I've been poring over the skem, it's a pretty basic design, with some
measures to reduce radiation from the oscillator.  No BBOD's, but all
bypass & de-coupling caps are bathtubs, which could be more of a problem
if they're leaky and I want to go into the "re-stuff" mode.  I'll get some
pix on a webpage in a few days.
    Can anyone shed some more light on this neat old item?
tnx, 73,
