turn engages gear on main shaft...   I've got 3 speed shift, so had CRS

Subject: [GreenKeys] MOd 28 Gears Question


Hello all...

Working on my model 28 KSR, have 3 sets of gears. One set is tied together
and is labeled 100wpm. ( small inner gear and large outer gear)

The other two large gears are not labeled
and I have one other small inner motor shaft gear that is smaller in
diameter than
the shaft gear for the 100wpm gear set.

I swapped them out to use the smaller inner gear and the largest outer gear
and it appears I am running at 56 baud. Using mtty into the tu and
then to the 28, I get perfect copy at 56 baud mtty setting.

I would like to get this on 30mtrs but need it to run at 45.45 baud.

I swear I had this on the ham bands at one time many years ago
and it was running 60wpm. But I can not come up with a gear
combination that will get that speed.

Does anyone have info on the correct gear combination for 60wpm?

I could do a speed conversion in software, but that would mean I am not
running the 28 directly as it was supposed to be run, and I would rather
have it run straight and clean.

Any help or ideas are greatly appreciated.

Thanks and 73's
