[GreenKeys] 33s

I know Wayne has helped me for years, and I don't lean on him too much, but I will!
OK so I have 4 33s here, one prints fine, its the one Wayne built, but heck it got shook in transport.
Keys don't agree with that typed.
Other is stuck on carriage, won't return.
I have two more, hundred for both, turned them on and they try to print.
There is another pin feed out there, good buddy picked up after an ebay buy, and thanks.
We have not figured out transport yet.
Now, what to do, or specifically, what not to do?
There are so many tricks, that H-Bar one from Wayne, what else does the collective have, and can we post it here or build a document?
Your secrets will be published. Could become a book.

An old Navy Univac computer that works.
Only slightly on topic because there is a 35 KSR (maybe the main console?) that we don?t get to see in operation and also a Kleinschmidt printer.

It's nylon, so it's 1950s or later.
It looks like something from the motor power train of a
Teletype Model 33. See:
https://www.vintage-computer.com/images/asr33_4.jpg
I don't really know those models well, but they did
have some nylon gears.
The tickets mentioning speed indicate it's part of
the power train, and you can change gears to get
different speeds or operate on 50Hz.

As a repeater owner of a system in SoCal it is interesting to note that per local requirements from TASMA, SCRRBA & 220-TASMA all coordinated repeaters are REQUIRED to run PL on the uplink due to the population of operators.? My system, W6CDW, on Elsinore Peak, runs full PL for both up and down link and still has an occasional issue.? With 3 operational channels on 2, 1.25 & 70 cm it requires 3 control operators to oversee daily operations and they do a fabulous job.? Incidentally, we are also available on echolink and allstar which presents another set of considerations.? Here in Texas there are more repeaters than operators so the "rules" are not quite as stringent.? Please feel free to stop by and shoot the breeze sometime.? 73, Cliff? W5SQI / W6CDW

many miles the height of the antenna above average ground level calculated.
After a few years the FCC relaxed the rules and now the repeaters are not
regulated very much.? Anyone can just put up one anywhere they want and
stick their own call on it.? Not much difference in just setting up your
home station.?
When I got into RTTY there was a RTTY repeater on our 220 MHz band with
about 20 users.? After a while the users dropped out and the repeater went
off the air.?
Now in the US in many areas the 2 meter and 440 MHz bands are filled up and
there is sort of a priority of giving any pair that opens up to the digital
voice type repeaters.

Dunno about USA, but here down-under you'd get strung up by the nuts if
you tried that on a voice repeater; for starters it would likely be
illegal.
That said, there was a mixed voice/RTTY repeater in Sydney; I have no idea
whether it's still operating, as RTTY (on other than HF) is all but dead
and I'm no longer in Sydney.
Quickly checks the callbook: nope, VK2RTY is gone...
(Here in Oz, repeaters are separately licenced and are administered by a
club or other organisation; they, along with beacons, have the callsigns
VKnRxx.)

Actually, no, you are NOT required to run PL.? You are required to run
some form of input protection - in other words, not operate carrier
squelch.? That may be PL, DPL, NAC, or some other system that will
prevent an un-intended carrier to key up the repeater. For a RTTY
repeater, that would most likely be Mark tone.? Back when 146.70 (and a
few others) were operating RTTY, you could not key up the repeaters
without Mark tone.? There are several analog repeaters that use
something other than PL or DPL for input protection, and of course none
of the digital repeaters are using PL.
BTW, it's 220 SMA (not 220-TASMA).? I was a 220 SMA co-ordinator for
many years.

Message-ID: <[email protected]>
Content-Type: text/plain; charset="us-ascii"
Thank you John. I'm not "dreaming things" then :->. I've successfully
followed your directions with the principal variance that I used Kroil
(on-hand) rather than Locktite freeze and release spray, applying several
drops several times around the piston shaft at the outer end. I chucked a
piece of bar stock firmly into a vise and used that to get a firm purchase
on the flat-lip (not the correct designation, I'm sure) near the end of the
shaft. And then exerted a steady firm pull until the shaft suddenly slid
along its range. Then was able to remove and inspect. Two different places
on the shaft were essentially "varnished". After cleaning those, inspecting
the bore (clean!), and then checking the leather seal (looks and works fine)
I reassembled and lubricated using 5W-20 synthetic oil (on-hand). Now
sliding smoothly and acting like a working dashpot :->!
Having set up a local loop I see that I've got another problem or two
somewhere involving the type-basket. But at least the CAR RET works fine.
And the BELL too!

Subject: [GreenKeys] M15 with Frozen Dashpot
I've had that happen. Someone used a lubricant
with heavy fractions, and the light components evaporated leaving
the asphalt component behind. This is why I lubricate machines
with 0-20W synthetic motor oil, which has no heavy fractions.
It's reasonably easy to get the entire dashpot out. Then
remove the top, so you can get the piston out. The shaft
is probably stuck where it goes through the top.
That's metal to metal, so you can use Locktite freeze
and release spray. That shrinks the metal and opens
up enough space for its penetrating oil component to get in.
Once you get the piston moving, take it out and clean
the inside and outside of the piston shaft and hole of
whatever gunk was jamming the piston.
While you have the piston out, check the leather
seal on the dashpot. That's the only leather part
in a Teletype. I suggest lubricating that with
Hydrophane leather dressing, which is a silicone oil
used on horse tack. It won't evaporate and dry out.
(Incidentally, if you just paint that stuff on a
cheap leather jacket with a paintbrush, in
a day or two the oil will disappear, the leather
will become nice and soft, and it will stay that
way for decades. Doesn't change the color, either.)

Subject: [GreenKeys] M15 Restoration -- Type Bar Basket
Message-ID: <[email protected]>
Content-Type: text/plain; charset="us-ascii"
I'm in the process of bringing an M15 back into service after a long period
of storage. This is the unit that was previously used by a MARS member that
I've mentioned in previous queries. The dash pot is now unfrozen and I've
been able to set up a local loop. I'm using a REC11, so plenty of loop
power; the loop is currently running at 62 mA. The resulting behavior is
not yet explicable. As this is the first green keys "recovery" that I've
attempted I can use a bit of guidance!
The general behavior is that the selector unit and vanes appear to be
responding correctly to the keyboard. FIGS and LTRS shift/unshift the type
bar basket properly (controlled by the bottom vane) and the (FIGS) BELL key
works. Other keys work, but with sometimes incorrect results (although in
most cases given the lack of printing it's hard to discern beyond obvious
consequences like a SPACE resulting in a CAR RET). The principal behaviors
are that:
1. No type bar is ever triggered, nor does the ribbon advance. The type
bars are all freely moveable.
2. Key presses appear to advance the type bar basket double; 38
key-presses advance the basket across the full width of the platen and then
further key-presses have no effect.
3. CAR RET causes either a full return, or a partial return to approx..
the 10-char position (in which case a second CAR RET returns the basket to
full-left). It's always one or the other.
4. LINE FEED usually works, but not always.
I notice that the PULL BAR BAIL floats forwards-and-backwards rather than
being held firmly against the front PRINTING BAIL BLADE. This doesn't seem
right to me. Perhaps I have a lost or incorrectly positioned spring
somewhere?
The PULL BAR BAIL behavior, what appears to be double-advance per key-press,
and the lack of ever triggering any type bar, seem to me to be the key
anomalous behaviors.
I can imagine that there may be a timing problem (or perhaps related
lubrication problem affecting vane control) resulting in erratic behavior on
a per-key basis (even the space is erratic, sometimes causing a CAR RET),
but I'd like to first get "basic operations" functional before probing
further.
I have not at this point attempted to clean and (re)lubricate any mechanisms
beyond the dash pot. I absolutely want to avoid major disassembly, unless I
have no other option. I don't trust myself to get it reassembled and
adjusted properly afterwards! I do intend to go over all of the lubrication
points once I'm closer to working order.
Do I need remove the type-bar carriage, invert, and check/lubricate
everything there before proceeding further? I don't think that would affect
the double-advance per key-press behavior, but I have much to learn.
I do note that it seems as of the motor generates a lot of ozone. But it
sounds completely normal to me; hums right along.
Your thoughts? I'll keep studying TM11-2215 .
Thank you,
paul

I?ll read this over more in detail after lunch, but the first thing that comes to mind is to oil/lubricate? always oil and lubricate. Going to cause major problems if you don?t ;o ?
?the second real thing (for now) is to take out the type basket and un-seize the ribbon spool shafts. Every time the basket advances, interconnected gears advance the ribbon. If those are frozen, then it?s probably gumming up the works on the rest of the basket and if you?re not careful, you?ll have a bent part or even a stripped gear.
That?d be my two first line of attacks :) . Good luck ^^ !

I would say you are on the right track.
The pull bar bail should engage the selected
type bar and throw it against the platen.

it sounds like your errors are caused by
the vanes not being selected properly.
First suggestion I have is turn the motor OFF.
Have the kbd and sel. mags in the look.
Press a key such as R;
Slowly rotate the motor (using the fan) in the
proper direction;
the kbd should generate the proper bits as the
motor turns;
the sel. mag. will respond to the mark or space
from the kbd as you turn the motor slowly;
after the 5 bits and the stop bit, the vanes
should be properly selected for the R
(I suggest R because, like the RY test, it is
the code where each vane is opposite to the
adjacent ones).
if you don't type anotheer character on the kbd,
then continuing to rotate the motor should cause
the printing functions to follow through...
if the vanes are properly set, the watch the print
bail and see if it catches the R typebar;
whatever does not work in that sequence is where
you need to focus attention first !
do the vanes flip back and forth easily ?
did the selector magnet pull and release properly
for each code bit?

Is TM 11-486 perhaps published under a different number by the USN? Or

Paul,
I just took a closer look at that page and there are two pdfs for TM 11-486.
Item 7 is the 1954 edition
Item 13, "TM_11-486.pdf" is the 1945 edition.

I?ve got a copy of 11-486. It is about 1200 pages and I?d have to rip it
apart to run through my scanner / or spend many boring days doing it one
page at a time. Best to wait for Google to do it some day!
Look here for some other Army/Navy manuals that may be of interest.

I have a very large binder (old brown Teletype leatherette type with the ribbon logo) which contains what I believer are a complete set of 15/19 manuals (except for table) plus some original (1953) model 28 manuals and other assorted goodies.
Anyone interested in that?

Because of all sorts of increasing QRM, VK (and perhaps ZL) has settled on
a standard CTCSS tone of 91.5 where needed; our emergency support service
(WICEN) uses 123 for historical reasons (and it's just as well that we use
50Hz and not 60Hz!).
Boards are available from the usual sources; they can be strapped for
any CTCSS tone, and the level is easily adjustable. I guess that would
upset the purists though, but that's progress for you...

Update: Thanks to all for the testing help.
In order to get my software to parse properly, you should use a CRLF before and after
the QSA query line:
?<CRLF>KE3BK KE3BK DE YOURCALL YOURCALL QSA?<CRLF>?
Thanks & 73,

My point is- when a voice net is going to be held, could the net control
turn off the Channel Guard for the hour or so the net will last if there
is no interference experienced? I fully understand local conditions may
preclude this, but here in Central New York it would usually be fine.
Hacking up legacy and military surplus equipment is something many want
to avoid. Some of us would like to get our fifty year old 2 meter
handheld or shoulder bag rigs off the shelf once in a while for
something other than simplex. As for RTTY repeaters, why not call them
up by hitting "LTRS-LTRS- CR" and whatever appropriate ID is needed at
the beginning of each transmission instead of Channel Guard tone? Other
countries may have different regulations.

I think I am still missing a trick or two here...I tried every combination
of 8 and 7 even/odd/none/mark/space and I get no printing at all with 8
bit, but moderately bad spelling errors with 7. See attachment below...
presumably this means I have the non-parity keyboard?
thanks in advance for your thoughts!
