[GreenKeys] Kleinschmidt TT-4

[David S]

I have a Model 28 wall mount that fits in my military truck, but is 
100wpm and not really usable on the air.  Will be a great demo piece for 
shows and such, and if nothing else it IS a printer.

I have a Model 28 floor mount that does not fit in the truck (it would 
fit in a strict sense, but not really be practical with the features it 
has), but I am working on getting it on the air from my home office, 
struggling with the terminal units though.

My real goal has been to get an on air capable Army Signal Corps model 
of some sort to use at events and Parks on the Air.  I finally managed 
to get my hands on a beautiful Kleinschmidt TT-4 machine and I really 
couldn't be happier.  It will fit perfectly in my setup.

I found a really nice copy of TM 11-2234 at a bookstore in southern CA, 
and have been reading through it.  I am getting it cleaned up, it 
appears to have been travel locked a long time ago, and it has some very 
aged grease in it.  It was stored beautifully though.  Very minor 
corrosion here and there but it is cleaning nicely.  Pictures are with 
covers removed, but the machine windowed cover and weather cover are 
both also in good shape.

Its tuning fork was missing but I (fortunately) found one on ebay for a 
reasonable price.  Reading the TM, and seeing this on the deramp youtube 
video on the tuning fork procedure, it is a fascinating method of 
setting spin speed.


Any tips on getting this TT-4 connected and running?


I am not there yet, but I have the deramp interface board adapted to the 
Model 28, would this be appropriate to drive this TTY, or is it 
expecting more of the current loop signal a model 15 would be getting?  
I have an iRL FSK-1000, but it wont drive the Model 28s, either it isnt 
working or I am doing something wrong.  Ran though the manual on the iRL 
a couple of times and haven't cracked that code yet.

The only references I see is a handful of youtube vids from gregga1973 
and Marks tech channel, not nearly as extensive a reference set as the 
Model 28.

Looking forward to not only getting this TT-4 running, but on the air
