[GreenKeys] MOd 28 Gears Question

[Don Robert House]

Steve,

If you clean up the gears carefully in most cases you will find a TP 
part number.  The number can be compared to a chart to give you the 
speed you are looking for.  I will put the chart up on our website 
once I find it.  It might also be found on George's website:

Regards,

Don

>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
