Subject: Worth of 75A3?
I acquired some equipment a while back which I am cleaning up and testing.
I've just gotten to the 75A3 which is good condition. Front panel only has
a little paint missing around the cabinet mounting slots. Seems to work
fine on CW and SSB. It has an FM unit and a crystal calibrator. I'd like
to get an idea what this is worth.
Also, I thought I had an 800 Hz filter for it but it is much smaller than it
should be. Its in a black plastic case .5"x.5"x2.5". It has 109M in a
circle, and 252T in a hexagon, with "F 455 FA 21 6814", and "526 9427 00".
The "8" in quotes could be a 3 or 9. I'd like some info on this filter also.
I've been cleaning up some Hammarlund gear is well. I have an SP-600,
HC-10, and SPC-10 all in good condition (and working). I also have a
cleaned up but not tested HX-500, and an HX-50 (still dusty). If anyone is
interested in any of this gear, send me a message.
Thanks,

I have been swamped with requests for the details on this unit.
John Brewer has been kind enough to try and scan it and have it available
on his web page. I'll let him get the word out if he is successful.
That should reduce the number of hard copies I would need to mail.
I am leaving on vacation today (for a week) and will be away from email.
After John has it ready on his web page, then once again, I'll ask for
those of you that can't access the info off the web to send me a note.
Depending on how many still want me to send copies, I may ask for a SASE.
I don't mind spending a few bucks to mail stuff out but it would have run
well over $20 in postage. Gotta draw the line somewhere :-)

Hi, Ken!
Sorry to be so long in getting back--busy week last week and then I
spent most of the weekend vegetating.
You are, of course, correct about the T-bar on the Logan bug, it's for
carrying and not really long enough to do the Mac trick of flipping the
bug up on its side for straight-key use; nor does Les's dual-paddle lend
itself well to such use anyway. (However, it can be done in a pinch--I did
try it!)
Nicely optimized as a handle, however. Given SF's busy seaport, would
not be surprised if a good many "Sparks" walked up the gangplank with one
of these keys. (And perhaps the stiff springs commented on by some
correspondents made the bug a little better behaved at sea. Add some
damping to the U-spring, with a "preloading clip," a bit of sponge or even
a hunk of gum eraser and the "split dits" that characterize this key go
away).
Many folks have commented on the lousy metals & plating Les used, and
'tis true enough; but his "human factors" engineering strikes me as quite
good. (T-bar, adjustable-height paddles, etc.) While he didn't build
"hundred year keys" like Vibroplex, I doubt his customers were considering
that long a term. If they kept the key clean and dry (nickle plating on
the adjusting screws &c is thin), it would hold up fine for decades; not
bad value for money. The design's not very original (others had done the
adjustable paddles, integrated dit-return spring and stop, and Mac's bugs
pioneered one-casting base, yoke and T-bar, which is one more step than
Les took), but it's solid, workable and well-integrated.
Nameplate on mine is oriented to be readable when the key faces the op,
and has "Speed-X" in an arc at the top, with the usual lines above & below
all but the X. Next line is about on the centerline and reads "MODEL
500," with "LES LOGAN CO." under that, and at the very bottom in much
smaller type "San Francisco Calif USA." It's the standard raised
bare-metal letters on black background with a border of raised bare metal,
much like a military nomenclature tag. Paint's quite faded.
73,
--Bobbi
