[GreenKeys] Teletype House Call

[Duncan M. Brown]

Thanks to George for taking care of the TTYs at KSM!

In the photo at  http://www.radiomarine.org/TTY/TTY-004.jpg, what are all
the controls on the 28ASR cover? Are they stock?  I'm familiar with the 2nd
perf "Tape-out" button, but never seen any other controls there.

Thanks for keeping KSM running,

> When's the last time you had a house call from a Teletype repairman?  Not
recently, I'll wager.  But that's just what we had last Saturday at KSM.
>
> In response to my message to the Greenkeys list George Hutchinson packed
up his Teletype tools and drove down to KSM from his home in Sequim, WA. 
He and Rich McClung showed up at about 1pm ready for business.
>
> First the problem with the Model 28ASR was addressed.  George quickly
unlocked the keyboard (the original problem) and then spent almost two
hours removing the typing unit, lubricating everything, cleaning contacts,
reassembling the machine and giving it a tune up.  By the end of that
process it was running sweet at 60wmp and 100wpm, maintaining lock even
being fed a significantly distorted signal.
>
> The next item was the Model 28KSR that we plan to use as one end of a
land line order wire between transmitting and receiving stations.  This
unit worked but just barely.  George looked it over and declared that the
typing unit should be swapped with one from a Model 20RO we had on hand
that was in great shape.  The new typing unit got the usual lubrication and
tune up before being placed in the 20KSR.  It too now ran very sweetly at
both 100wpm and 60wpm.
>
> Rich and I agreed that it was a real pleasure to watch a master at work. 
Clearly, George knows Teletypes inside and out, a skill that comes only
with long experience.
>
> After several hours work George packed his tools and test gear saying "my
work is done here."  The three of us went to the Station House Cafe in
Point Reyes Station for a dinner that couldn't be beat.  We agreed it was a
great day before parting ways.

photos.

> Thanks very much to George and Rich for generously making their time and
skills available to help the MRHS move toward another goal.  Once we have
the TTY land line link working between the two stations it will be another
step back in time to the days when such links were common.  When that link
is inaugurated - this year we hope - we'll be communicating the way
transmitting and receiving stations did in the golden years.
