I am looking for the input impedance of an 8877. I found one source and that
was K6DC's (SK) article years ago that said it was 54 ohms with no frequency
dependency or reactive component. The input C is 42 pF according to the data
sheet. So I will assume I can use 54 ohms in parallel with 42 pF. Anyone have
anything different?

I can confirm that is a good value. In my homebrew amp I used a simple
LC parallel resonant circuit with a Q of about five on the input and got
an input SWR of no more that about 1.3:1 from 160 through 10 meters.
