Hello, Carl..
There is a nifty disk that came with the ARRL Handbook
that deals with Pi, Pi-L, and input Pi networks, based on
the universally accepted formulas by W5FD. You just enter
your values, and you get a nice print-out of the L and C values
needed. I use mine all the time, and it is very adequate.
