[GreenKeys] Vintage Computer Festival Teletype 101 Update

Sun Apr 3 12:15:17 EDT 2011

Is anyone on this list going to the Vintage Computer Festival in Wall, NJ (vintage.org), this May?  I will be running a teletype 101 workshop with a focus on attaching an asr 33 to a computer.   This is teletype 101, for people who never used a teletype, and not an advanced class for technicians.  (I am not a technician either).  If you're an expert you can skip the 101 part and dive right in as we'll have many teletypes to play with.  There will be more than 33's there, I believe we have 25's, and other models.  

If anyone is interested in buying a teletype from our computer club (midatlanticretro.org), I believe we will have at least one or two available, maybe more.  We have about 15 in our museum and don't need them all.  I think what we're going to do is apply the $40 workshop fee towards the purchase of a teletype, we can discuss how much more if would cost on top of the $40.

There will be a door prize of a free ASR 33.

     Teletype roll paper is still available from a number

of sources.  Try eBay, and search for "teletype paper".

     5 channel 11/16 punched paper tape is available from

    http://www.westnc.com/paper-tape-rolls.html

     I will have 5/16 paper tape for Model 14 printers

available next week.  I've had rolls made in China, and they're

now in DHL's Hong Kong sorting center awaiting air shipment.

Everyone,

Thanks to all for the great info on my paper and tape needs.

I finally decided to tackle the machines and re-learn a lot of what I almost

forgot or never knew. The leg-bone connected to the thigh-bone etc...

As I mentioned in my reply to Tom, some of them took some real head

scratching, plus some never-to-be-forgotten lessons in the holding power of

60 year-old grease.

Jack... good to hear from you. Are you still upstate or does that new call

(love it!) mean that you have moved?

73,

Ken

In response to few queries as to just what the GRC-26 is, here is a brief

rundown...

The GRC-26 is a transportable shelter, about 7' x 7' x 14' on the bed of a

GMC M-211 two-and-half ton truck. It doesn't have to be on a truck. Dropped

onto the ground, it can be called an MRC-32.

Mine is the -A version. It uses:

- a BC-610H and BC-939 Tuner

- two R-388's two TG-7B's (modifed by B&W into something called a TT-55 but

still a TG-7B).

- A Model 14 Typing Reperf and the accompanying TD

- A control unit that routes the TTY lines inside the shelter

- A dual diversity frequency shift receive converter that works off the 2 IF

outputs of the R-388's

- A Frequency Shift exciter O-39/TRA-7, essentially a 90 pound VFO with F.S.

capability, that feeds the BC-610

- A couple of LS-3 speakers

- An A-11 aircraft clock in a cute little box

- A pair of EE-8 field phones ("Run a pair of wires from the interior of the

GRC-26A to the cab of the truck in order to communicate with the driver."

Talk about hands-free driving....)

- Lots of other accessories including "Broom, floor"

- Great big transmitting whip, and provision for three smaller receive whips

- Storage straps on the side of the shelter for poles for two big dipoles...

the preferred setup for dual diversity

The entire left side of the shelter is taken up with a monster storage

cabinet.

The earliest version used a pair of BC-342's (110 vac version of the

BC-312), modified for increased stability.

Later models, down to the -D version used later model TTY gear (RATT as the

manuals call it), along with R-390A's and a T-368.

The purpose of all versions was the same: basically tactical or mid level

TTY origination and relay, along with voice capability. Some guys who used

it in the 50's and 60's report the inclusion of encrytion and code burst

gear. CW was an afterthought: J-47 key on a leg clamp. Because it used IF

detection for the TTY signals, it was also possible to voice modulate the

BC-610H while transmitting and receiving frequency shift TTY. By using

separate receive and transmit frequencies, full duplex operation is

possible, using voice and TTY simultaneously. Talk while typing, so to

speak.

Curiously, you throw it from R to T with a big clunky switch on the C-808

control unit... the PTT line from the BC-614 speech amp connected to the

BC-610H is left unconnected. So using either the T-50 or the T-17 for voice

required flipping the switch and still holding down the mic. button.

As Jack knows, I have been taking my time over the years first with cosmetic

refurbishing of the shelter itself, then with the radio gear. I bought it

from Fair Radio years ago and it was a mess externally. But inside, it was

like a time capsule from 1952, including spare ribbons that still type.

Nonetheless, the TTY gear hadn't been touched in almost 60 years, so as

great as those machines are when they are running well, they needed major

overhaul, which I am just getting around to now.

Anyway, that's the short version of the story. Then there's the truck... ten

tires and two heavy duty batteries among other babysitting chores...

73,

Ken

With an Icom IC-761 running the RTTY filter and a 102' doublet

at 40' fed with open wire line and an antenna tuner, you're an

S9+ here in Ranger Texas.

Does anyone have, or know where I can obtain, a manual for an AN/UGC-77? 

This is my latest addition to my "herd".  It's a very nice clean machine. 

I don't see a traditional power cord/cable of any kind so I need, first of

all, to know how/where to connect power.  It has an external box marked

"ESA 323120" that has a 3-conductor cable with spade connectors.  No power

cord on this unit either but an On/Off switch.  The typing unit appears to

be like a 28 but the keyboard seems to me like a 32 or 33.

I had a nice visit with Jeff Angus who was the first GreenKeyer to see my

new acquisition.  It's nice to meet a fellow GreenKeyer face-to-face for a

change. If you find yourself near Ranger, Texas don't miss an opportunity

to visit Jeff's store in beautiful downtown Ranger.  As he says, he has

everything from crackers to coffins.  I am not in the market for a coffin

just yet so I didn't make it to that part of the store.

Does anyone on this list have a manual for a Frederick Electronics

Model 1250 Tuning Scope? It's a rackmount scope in a 3.5 inch tall

panel, rectangular CRT, that's used with Frederick RTTY converters.

I need a copy of the schematic.

Thanks for the plug Kevin.

It was a good way to pass a few hours, sitting up front in the store

and just swapping your usual lies and horror stories.
