[Boatanchors] USS Midway notes

[The Pollacks]

I believe the Hammarlund is the HQ120, or 120X (the "X" had the crystal
filter in it).  One way to tell is to look at the tubes; the 129 has all
octal, and the 120 has tubes with grid and/or plate caps.

I have manuals for both that I can copy if you like, and live in the San
Diego area.

I had the opportunity to see some "behind the scenes" things on the U.S.S.
Midway this past weekend while in San Diego.  Friend of mine over there is
part of the restoration crew for Communications so we went past the
barricades so to speak.  Lots of stuff there in storage that hopefully will
get put into working positions in the future, mainly receivers of a great
variety.  One of the ones i noticed early on was either an HQ-120 or 129
that had tags on it identifying it as an RBG-2 or component thereof.  Front
of it looked pretty good and it was in a cabinet so i didn't go any further.
I do have pictures of it though if anyone wants to see how it's tagged.
 
Something i saw on a shelf in one of the radio storage/work compartments was
an Abbot TR-4 setting up on the shelf.  Wonder how that got there.
 
They haad numerous TCS arrangements along with power supplies, RBB i think
was another.  An RAK-4 was setting on the floor as well.  Then as a surprise
i was looking at a couple of thin front panels stacked one on top of the
other and with a bit more looking found a pair of TMC STE-5 units with the
correct plugin modules.  These happened to have sequential serial numbers
and looked pretty good.  One was on a 4 mc channel and the other on an 8 mc
feq.  
 
Their ham station, NI6IW runs a W7QHO command set and modulator along with
an Hammarlund Super Pro.  
 
Lots of work to be done around there, just needs to be someone there to take
care of it all.  Get it cataloged, then organized and wiring work done.
 
An SP-600 at the residence of my friend had a tag on the upper right corner
of the front panel saying it had been modified by TMC for diversity
reception.  Having not seen one i thought it might be of interest to the
group.  I also have a picture of the tag on it.
 
Even though the weather was less than enjoyable Saturday, being on the ship
and seeing what they had to play with was lots of fun.  There were a variety
of 1051 type receivers laying around as well.  The main receiver
communication room had columns of them stilll in the rack but i've heard
that they had been "de-mil'd" which meant cutting of wiring and other nasty
things.
 
Lots of TTY stuff setting around on display and it looked to me that once it
was found out where the wiring ran to, (a common rack?) that this would be
fun to get running.  28 ASR's, one at least with a separate reperf under the
cover, a bunch of rack or shelf 28 RO's and a couple of KSR's rounded out
the livery.  Numerous 28's in the back rooms that had been run and checked
out for spares.  
 
Can anyone tell me what speed the 28's ran at.  Were there different speeds
depending on whether they were running on an internal shipboard circuit or
external to the ship.  I'd think maybe 100WPM would have been a standard but
i don't know.  Did all machines in the main receiver room terminate at one
patch panel bay or were they wired direct to another machine somewhere else
on the ship?  Lots a questions on this.  Come on you Navy ET's.
