I found a beautifully maintained Model 28 with fascinating features. It has a paper winder, switch on the keyboard to activate a radio key for transmit, and it included a terminal unit. It is geared for 60 words a minute so this is what I would need to participate in on air teletype contacts. Not having been confronted with the need to connect to a radio for transmit with the other teletype, ill have to figure this part out. I have listened to RTTY on the air, but never attempted to transmit on it and the details of this are not obvious. A place to start seems reoccurring RTTY nets at 3905 Century Club, figure out reception, then work on transmit.
This machine will be a great addition to the M35a2 setup, but ill have to make some choices on layout, ill likely be able to fit it with some shuffling and some way to shield it from shock while moving.
