Will be a bit before giving it a try. Fooling around with the 9912 board for now. The bit whacker would be the best way to solve freq control problem. How abt a small display and encoder??? Jim - KB2XJ Hi Jim, I really like the bit whacker. USB, boot loader, and lots of i/o for displays keyboards etc. The only reservation I now have is that Sparkfun raised the price from 19.95 to 24.95 which puts it very close to some really nice alternatives like the AVR AT90USB. BTW, it was really nice to meet you and your sister at Ozarkcon. 73, Tom KM5H
