[GreenKeys] Intro -- new to the list but not to RTTY

Jim, W0EB:
 
The old equipment ran better than some of todays' junk because it was built 
 to last
and built to be reliable at a time when the military demanded quality from  
industry.

Jim,

Welcome1

The "Coke Machine" you refer to  was probably an AN/TGC-1, the first of the 
"store & forward", torn-tape  relays.  It was made by Teletype Corporation.



There is only one or two of  these still around that anyone knows about.  
One is owned by K6OSM.   Later, both Teletype Corp. & Kleinschmidt Labs made 
fancier ones,  generally 6 or 12 channels.

I was an Army-trained TTY repairman.   In 1966, we trained on both the 
M14/15/19 and on the Kleinschmidt TT-4/98/76,  FGC-25.  Also trained on the 
TGC-1, though it was obsolete at the  time.  I guess it was just to give us a 
feel for tape relay  equipment.  

have fun,

Hi all -- Been an RTTY enthusiast/operator since I was first licensed in 
1963.  I was in the Army, stationed in Northern Japan at the time.  Over the 3 
years I was there I got to work with a whole bunch of older Teletype Corp. 
Model 14, 15, 19 and there ancillary equipment.  I was operating the base 
MARS station during the big earthquake that tore up Anchorage, Alaska back 
then and because of our location, propagation wise, we handled most of the MARS 
health & welfare between Elmendorf AFB and the U.S.  We had one unique 
piece of equipment that we called the "Coke Machine".  Not sure what company 
made it but it was a stack of typing reperforators and 
transmitter/distributors.  Receivers were Collins R-390A's and the transmitters were OLD (even then) 
BC-610's that ran about 400 watts out.  We did have one huge 5KW CW/RTTY 
transmitter (don't remember the number but it used a pair of 833 triodes in 
push/pull).  We were set up to receive & transmit simu

 ltaneou

sly on several frequ

 encies and picked up the traffic from Elmendorf on 8.080 MHz, 
re-transmitting it to AF Headquarters in Hawaii on 14.832 MHz.  The typing reperfs were 
punching tape and when it got long enough, we fed the tape into the T/D's 
for re-transmission.  We also were communicating directly with Hawaii on 
13.995 MHz using another BC-610 and Model 15 so if they got a garbled message, we 
could stop the tape and either back it up or break the bad msg out and feed 
it into the T/D on the "order wire" re-running it until they got it.



Haven't had to do anything anywhere near that hectic in the years since, 
but we really wound up with a sense of accomplishment and a lot of thank-you 
letters from the Army, Air Force and the recipients of the messages.  Amazing 
that the mechanical machines ran better then than some of the electronic 
stuff we use today - LOL.
