Does anyone know of a design for a valve PA that covers both 2m & 70cm using
the same tube?
I'm thinking about a compact PA for these two bands, possibly using a HV PSU
from a Panasonic "Inverter" microwave, if I can get it to work.
Is it possible to design a common plate line, given that the bands are
harmonically related (e.g. 1/4 WL on 2m = 3/4 WL on 70cm)?
