** If Mr. Rauch agrees to send one of his suppressors, yes. What
instrument do you have access to for measuring impedance, admittance and
parallel-equivalent resistance? The measurements need to be made at
100MHz and 150MHz since that will cover both Henry's as well as
Ameritron-MFJ's 3-500Z amplifiers.

** At what frequency? At 50MHz, Ni-Cr #18-wire is c. 5.5 x more
resistive than #18 Cu.

** Since all of the anode current passes through the R/L vhf suppressor,
it's not all that complicated.
