Q: What is this Russian equipment ?- includes a paper tape printer - Model
ARGON-B
A: Strip printer for radioteletype interception - see info
here
ARGON-5 is a variable-speed teletype printing unit
used in intercepting radio-teletype messages. It is fed by the ARGON-4
demodulator, presumably fed by a radio receiver. The “SETTING” dial
allows the operator to adjust the bit length in milliseconds. Assuming that
the intercepted traffic was encrypted, it seems odd that this is just a
printer and not punching tape for later analysis, but what do I know….
It was evidently used in this mobile radio intercept
unit.
Q: What equipment is this for? I presume British Air Ministry?
A: Part of BC-640 transmitter - VHF for ground to air comms - joint US/UK
equipment like SCR-522

Q: What transmitter-receiver is this? (circles indicate tuning dials?)
A: 8/2021 - TCQ, 30w, 2000-9050 kc
Toolkit for ??

Q: What are the two black units to the left of the Teletype gear? 1959 USS Pyro
AE-24
A: RBO-2 receivers with the Escutcheon Covers in place. These covers were
added
after the RBO-1 contract to reduce RFI to the receiver.

Crank for ??
Solved! - Ken VE4HMQ says:
"Used on Teletype M14 tape printers or TRP's to adjust the range finder thru the front
of the printer thru an access hole in the cover...
This is a Teletype Corp'n modification kit, it enables Wire Chiefs to adjust the range while
testing circuits...
It is a geared linkage set up, and the crank is differently angled to clear the keytops
while turning it..."

AN/URH-2(XN-1) VLF Receiver-Recorder - used to log VLF propagation.

Western Electric 7B "upside down" test-desk key. It was mounted
below the desk (e.g. the 17C toll testboard) with the knob extending above the
surface. (AWA Journal vol 32, no 2)
What is this module?
What is the glass rod for?
A: Delay Line - this is a radar calibration device
|
The rod looks like glass - might be quartz but it is awful
big for that! The "socket" has a single lead that goes to a
spring-loaded metallic contact to the center of the rod's base. The top of
the rod is spring loaded too. The base of the rod has a ceramic(?)
"button" that measures infinite ohms between the silver coated
outside ring (ground) and the center contact. |

Strange cover for Teletype M19 - Q: what is it for? |
 |
A: Ken W7EKB says -
"You have one photo of a "strange cover" for an M-19. I had
an exact copy of that at one time. It contained a Model 14 or 15 (?) TTY
plus a power supply and a tape punch. It was a "console" setup.
The cover is spring-loaded to enable it to be lifted easily. Mine came
from the FAA station in Missoula, Montana while I lived there." |
