RTTY Collection
(not counting most of the test stuff
- yet):
AEA:
a really neat little box
this: the 'MBA'
stands for Morse-Baudot-ASCII, and can input
any of its modes, and output
any of its modes. That
means you can translate between speeds on RTTY, or between Baudot and
ASCII, or even between 100wpm ASCII to CW (I suppose-never tried.) It
comes with a Centronics-capable printer port, and current-loop I/O, plus
5VDC ('modified') RS-232

This test set
was a purchase from Morry, K3DPJ-isn't it gorgeous? It's in as-new
condition, and wonderful for testing RTTY signals of virtually any speed
or persuasion. Thanks Morry!!!

Check this link to
RTTY.COM for
a great page on the development and workings of the
ST-5-which
(by proxy) also explains a lot of what's what with the
ST-6:
w/factory
cabinet; set of original bare, unstuffed ST-6
pc boards w/manual;
Circa: 1969.
RTTY.COM also really
delivers on an incredibly complete description of the
ST-6. Take a look:
plugs-into your PC, provides all the usual
modes, plus CLOVER;
Circa: 1995
low cost RTTY demodulator;
Circa: 1977
high performance RTTY demod.w/CRT;

1976
Finally,
probably the best
"ordinary" single channel RTTY TU ever made,
Circa: 1985
HAL
Communications ST-8000high
frequency RTTY TU (terminal unit).Purchased 'surplus' several
years ago, as NOS (New Old Stock), in original factory carton. It
included the original, separate, operation
andfull
service manuals.
The service manual was usually a $100.00 option.
The current
firmware revision is 2.0,
which is available from HAL for ~$50.00, in the form of 2 EPROMs. Tunable
in 1 Hz increments
for both HI & LO frequencies, the modem in the
ST-8000 is widely
regarded as the best non-DSP unit ever
built for a HF radio teletype TU
The current list price from HAL for this unit is
$3995.00!

All the

I had to just put it in storage when I got it. I also have a couple of
Kleinschmidts in storage that may be worth fixing up. I obtained the
TT-4B back when I was
in ARMY MARS, and took the MIL refurb-depot wrapping off the box myself.
It's a jewel!!!
