Increase L-sup to lower the anode-resonance's Q and Rp @110MHz. // Use
a double-suppressor configuration. (An example can be found on my Web
site.)
- RE: Adjusting R-sup: The optimal ohms for R-sup is equal to the
reactance in ohms of
L-sup at the anode-resonance. Ideally, the VHF current divides in half.
