FW: Hardware hack - replacing a pot with a switch?

["Alan Kroeger" <nospam@developsolutions.com>]

Something else I just thought of you could use trimmer pots with the switch
and this would provide you with a fine tuning mechanism. The trimmer pots
could be of the same value as the existing potentiometer so, this could be
much easier to do then the way I originaly was thinking. Of coarse the
iniside of you PDS will start to have a bit of a dead bug circuit but, who
besides you should or will be looking inside of it.

Happy Holidays to all!

thanks a lot, Alan.  I think I'll dive in and (try to) remember where I 
started from in case nothing works.  I'll post if I have success.  have 
a great holiday too -
