''what a beauty''!
Stick 100 feet of wire to it and connect it to your gen coverage rx starting
low and keep going till you find it tuning correctly better still send it
to me and I'll do it ..

Actually there are 2 photos of what appears to be a BC-442 with a white
meter -- Figure 1, page x; and Figure 45, page 23.
Years ago I made a complete photocopy of an original SCR-274N manual. Will
have to dig that out and compare the pictures to be sure.
In truth, "th' 'lectric'ty don't care." But if it did exist, it'd be a nice
collector find.

If you're referring to T.O. 08-10-50
dated February 15, 1943, Figure 1 page
x clearly shows a black faced meter in the BC-442-A.

Does anyone know of any information on the net on this set up or even the
individual sets. I have a new in the box wth l all components, radios,
dynamotour, junction box, racks, control boxes, tuning units, coils, etc.
No Cables or plugs or information. Any help would be appraciated.
Thanks,

A manual would be helpful. Lacking that, try
http://aafradio.org/docs/RU-GF_junction_boxes.html - it has the junction
box ends, and the remote ends are identical.
http://www.ebay.com/sch/m.html?_ssn=kb4dmf will have some of the
connectors at a reasonable price.

Hi,
Does anyone have a source for a couple of feet of roughly 1/8" ID
Varnished Cambric Tubing? I'm trying to make up relatively authentic
cables for an ARB.
Please reply off-list.
Thanks,
-John

Try AES.
Also, try just radios.com in Canada. They have shrink and normal plastic
tubing - may have cambric.

I found this mystery black box in mint condition, still in its herm. sealed
overseas packing at the TRW swap meet. Does anyone have any further
information on it? Tech. manual availability? See photos here:
http://s1367.photobucket.com/user/kmmab/library/?sort=2&page=1
Description
Name/Nomenclature: Frequency Converter CV-27/UPN
Power: 115/80 Volts, 60/400 Hz, 1 Phase
Serial No. A-327
Contract No. CAON-2000-DAY-DE-AR
Stock & Part No. 1660-211 963 170 XD2 2C720-27
Name of Activity or Mfg.: Dayton AFD
Date: 16 Dec 1955
Tech. Order Compliance Record: 00-20K-11
Front Panel Description (left to right):
Top Row: Antenna Connector, Spare Fuse, Receiver Connector.
Middle Row: 4-Pos. Antenna Match Switch, 3-Pos. Switch (HF/ L.F.
Distant/L.F. Local)
Bottom Row: Power Connector, Power Switch, Pilot Light, Fuse, 115V/80V
Selector Sw.
Size: 6-5/8" Wide x 6-1/8" High x 8-5/8" Deep (Not including shock mounts &
controls)
Tubes: 6SJ7, 6SA7, 6X5
Probable Function:
With middle 3-position switch in the L.F. Distant or L.F. Local positions,
it probably converts signals in some unknown low frequency range to some
unknown high frequency range for tuning on an HF receiver. With the switch
in the H.F. position, it probably connects the two antenna connectors
together for normal HF reception on a connected HF receiver.
I found an instruction manual reference at:
http://books.google.com/books/about/Handbook_of_Operating_Instructions_for_L.html?id=r3mmtgAACAAJ
http://www.jproc.ca/hyperbolic/loran_a.html
The manual doesn't seem to be available in print or on line, but the manual
title says "Loran Low Frequency Converter", so it has something to do with
LORAN.
My own experience is with LORAN A using the AN/APN-4 in the Martin PBM
Mariner flying boat.
A good description of LORAN A can be found at:
http://www.jproc.ca/hyperbolic/loran_a.html
Questions:
So what did this black box do? Convert LORAN C to LORAN A? Can't be because
LORAN C wasn't invented yet in 1955.
What LF range does it cover?
What HF range is its output?
How was is used, with what receiver(s), for what military purpose?
Anybody know? Guesses welcome.

My guess it is to convert either:
LORAN-A to LORAN-C
or
LORAN-C to LORAN-A
or possibly both.
LORAN-A operated between 1.8 and 2.2 MHz.
LORAN-C at 100 kHz.
The transition was in the mid 1950s.
The APN-9A has BOTH bands. A very interesting toy that I'd love to play
with.
