[MRCA] [MMRCG] Model 28 tty

Mon Oct 8 11:28:33 EDT 2018

In the Coast Guard we phased the M-28’s out for cassette driven M-40’s around 1980/81. One issue we had was that our MF CW broadcasts used M-28 tape readers and we cut tapes using the M-28 so we had to keep them for several years. The M-40’s ate cassette tapes and were a PITA. The CG had a TT Rate that repaired the Teletypes but being a former Navy RM2/TTY repairman when we had boring mid watches I could be found in the ET/TT shop working on gear or working on a couple Model 20/25’s I used in my hamshack...  I still have spring pullers/pushers and a spring tension gage in my tool kit.. as much as I’d love to unwrap a NOS M-28 and operate one again the nightmares of TTY school remain PTSD - POST Teletype Stress Disorder...

What you don’t see is that now have added a RE-350K and a bunch of other Harris junk and am in the process of trying to move another bookcase for component storage and additional computer rack for the AN/UYK-19 project! If I did TTY would use one of the vintage computers.
> Another foot note about this last weekend one of the other things we moved were four wooden shipping crates with R-105A/ARR-15 receivers in them. We popped the cover of one box that all appear having been boxed up in the forties and there were the receivers. The weird thing was they were not NOS but appeared having been used but for some weird reason had been repacked in wooden shipping boxes for redistribution or some future use? When did they stop packing things in heavy wooden crates? And why would the government go thru such expense to save receivers like that?

> Think the base weight of the model 28, table and punch tape stuff all come in at around one hundred forty pounds and who knows how much more when you throw in all the packing and wooden container but it was plenty heavy.
> One unit is still sealed in its shipping crate but the other had the crate removed and looking at it there was all the paper work and manuals and stuff along with the test sheet from when the unit was inspected and accepted by the US Government back in 1970
> This brings up the question, how late was the government purchasing these machines? See from Wiki that they were still in production all the way up until 1981 with the ASR series being targeted at the growing computer industry.
> The thing is that with the product line being introduced back in 1951 and still being purchased by the military in the seventies they must have been in use until at least the eighties so that gave them a thirty or so year length of service. I am use to things like the UGC-74 or UGC-129 that are all long gone now but looks like the KSR-28 had a lot longer period of use. Was it the longest lived TTY?
