Hi Chuck - I also received my RIT boards for the xx-40 in the mail
recently, but have not got around to installing. I was curious, has
anyone seen a source for pots with a center indent for this RIT pot. I'm
wondering if you can eliminate the RIT switch by using an indented RIT
pot and having the RIT circuit always active. The only reason this may
be a problem is that maybe the RIT span is not linear for a center indent
and also maybe you need to add a compensation resistor to make the center
- "centered". So maybe this is not practical for a simple circuit - just
easier to switch in or out. By the way why do I want to eliminate the
switch - size (ps most add on switches to pots are NO so that will not
work - already thought about that method of including switch as part of pot).

Keep us informed Chuck of the RIT mod. I've been using it without by I
must admit I really do miss the RIT once in a while (leap-frogging is no
the best way to carry on a QSO - hi)
