Anyone familiar with Eddystone?

On my usual Sunday morning flea market crawl, I picked up an Eddystone Model
850/4 communications receiver today.  In my haste (I hate to miss a bargain
:-) I didn't pay attention to the frequency coverage (10 - 600 Khz) so
really have no use for it, except as an ornament which I have no room for.
Cosmetically it's very good (with the exception of one broken knob) and it
does work with no hum, but there's no VLF activity around these parts.
Any suggestions on what to do with it?  Is it feasible to attempt to convert
it (or make a converter) to cover at least the BC band? or just part it out
(it's too heavy to reasonably mail).  I mentioned it on the Yahoo Eddystone
User Group and have been told that only 200 of this model were made (Grade:
Ebay "RARE" - guess that's an option :-) ) so of course I haven't been able
to locate a schematic or much more information on it, except that it was
made in 1962.  Big brute of a power transformer - Primary 110 - 220 Volts,


with geared flywheel tuning, cast aluminum panel and parts of the chassis,
'prettily' laced wiring and so on.
Your ideas are solicited and welcome (I'll even laugh at the asinine ones
which have been known to follow :-)).

Cheers!  Haggis.

Asinine idea # 1
That is swell LW coverage, surely thou canst get 540 to 600 kh AM to test
it?
    Anyway, I wuz thinkin' that the audio part of those European stations
might be the only component that has enuff pizzazz to get across the
Atlantic and... ya might use a BFO to 'spot' a transmission and maybe hear a
few words of furrin gibberish.
    ...Allowing for all the Aetheric, variables of course.

Asinine idea #2
    Maybe you could tune in any of your AM radios' IF frequency, thus using
the EDDY as an AM receiver---as though all your AM radios were AM
transmitters!
    Maybe ya'd have to put a long insulated "antenna" onto the 2nd IF of the
EDDY. {"Mike" gave me this idea}

You could try posting this message in the rec.radio.amateur.boatanchors
newsgroup. Might be someone there with info about it, etc.

Phil Nelson

Are you in the States??

That is a gorgeous receiver. I'd think you could easily recoup whatever you
paid for it, and buy a comm receiver with BCB coverage, and have some
change to boot!  Don't hack it up or modify it is my opinion.

Hi Pete (and all the others who replied).

FWIW, I'm in the frozen north (Canada to be precise).  Sitting at a balmy,
sunny 75 deg. F today, which is a pleasant change from the torrential rain
and flooding we had a couple weeks back.
Yes, I should have put it on the 'bay, judging from all the offers I've had
to purchase it.  :-). I'm not feeling that mercenary today, and it is now
spoken for, so no worries about parting it out.  I didn't make a profit on
it (hey! anyone who was willing to pay the very high shipping plus the
little I asked for it, deserves it).  I'm just pleased to see it going to
someone who will appreciate it.
Seriously, it has to be one of the most beautifully built comm. radios I've
ever seen, and that includes the SX - 96  Hallicrafters and the RCA  AR - 88
I almost "gave away" a while back.   I have lots of pictures of the
"innards" of the Eddystone - if anyone would like to see them, let me know.

A suggestion I got about using a cheap table radio as a converter (although
it had merit) just wouldn't fly around my house - Mrs. G. would have to ask
"but why don't you just listen to the little radio"?

Back to my crystal sets. :-).

Cheers!  Haggis.
