[R-390] Tooth Error

[ka9egw at britewerkz.com]

Even clearer:

Another, clearer way to say it, is "Set the Geneva drive as shown on page
6-8 of the Y2K manual, assemble everything exactly as shown in Scott
Seickel's tutorial, except, before performing Step 10, rotate the idler
shaft installed in Step 2 clockwise by one or two teeth, as needed, of the
idler's larger gear.  Verify after assembly that 90+% of the bandswitch's
indexing takes place on the 7-8 upshift."

This is what I had to do on my RF deck, which had a blank red hangtag
attached that was not apparent til the deck was removed from the radio.  I
question if the geartrain being mis-assembled at the factory or in a depot,
was the reason for the red tag to begin with.  Electrically the deck seemed
fine.

YMMV.

Hi Brian,

You Wrote: I come to the inescapable conclusion that the drawing of the
geneva mechanism at 7+000 in the Y2K manual is in error by something less
than 1/3 tooth.

If you could please write up the problem and solution along with a reference
to the drawing I'll try to post a supplement or give to to W. Li to add to
his "Pearls" info.

Regards,

Perrier
