Nalc,

Thanks for the feedback. No reason not to put in the 100k-ohm resistors just to be safe. Or perhaps I'll put a 200k-ohm resistor across each parallel switch for symmetry...

Interestingly, the resistances seem to step up by 0.5 on a log scale--330, 1000, 3300... Those are readily available at Radio Shack so I went with those.

I did pick up on the short/long press seek/tune, but not Mode/mute. Cool. Good to know.

So the schematic looks okay to you? Glad I'm on the right track.
