[GreenKeys] Unadjustable Model 19 (15)

[John, W9DDD]

Lots of questions, and probably useless facts from me?

What's your source of RY?

What do you mean by setting it through MMTTY?

What does it print for an RY signal?

By speed adjustment, I suspect you mean the range adjustment ... the 
thing with a 0 to 120 scale.   (might be off on the exact numbers, but 
my recollection is that mid range is 60)

I'm assuming a 2100 rpm motor and can't think of anything you could 
reference it to for comparison.  (there were some 1800 rpm governed 
motors used on TDs, but I suspect they are quite rare)

For 60 wpm (45 baud), the main shaft spins at 420 rpm and the keyboard 
at 368, again can't think of an easy reference other than the keyboard 
is only slightly more than 6 x  60 Hz line frequency. (now that I think 
of it 420 is 7 x, but you don't have anything to get a timing pulse like 
you could with the keyboard.)
