Thanks Gil,

I enjoyed viewing your pages on TTY machines.  As I said, you have a nice 
collection,

I have had a number of TTY machines over the years, all used with ham 
radio.  I started out with what is now a quite rare model14 1/4" tape 
printer.  Then a TT-4TG by Kleinschmidt.  I then had a Model 12 with the 
non-synchronous motor that you had to adjust with a tuning fork.  I then 
graduated to a Model 19 set-up and finally a stand alone model 15 KSR.- I 
used them all extensively with ham radio and Mars before moving to computer 
RTTY.  Now that I am retired, I decided to assemble another RTTY station 
using the old mechanical machines for the nostalgia.  There was just 
nothing like the sound and the smell of oil in the air with the old 
machines.  And they remain one of the mechanical computing marvels along 
with some of the older accounting type mechanical adding machines.

I have a model 28 now that I am working on sans cabinet that I plan to 
mount in a close fitting plexiglass enclosure so that you can see all the 
parts work as the machine runs and copies RTTY.  Also have a Model 28 KSR 
in excellent condition removed from a radio station news room in active 
service, and a Model 28 stand alone receive only typing 
reperforator.  Also, two model 15's on the way.  So my collection is 
growing as well.  I have the offer of a Model 28 ASR but no where to put it 
as of the present.

I was in the Army signal corps 1977-1979 during the last days of torn paper 
tape RTTY relay stations and got to use some of the old equipment in actual 
communications operations. Sadly those days are all gone and most of the 
machines destroyed.

I plan to have a fully operational RTTY station up and running with Model 
28's and model 15's by the summer.  I just bought a used HAL ST-8000 
demodulator and already have several others.  I just wish there was more 
commercial RTTY traffic on to monitor these days.

Best regards -- Roy Norris
