I've got some 3-400Z spares and sockets... I think i'm limited
mostly by the cost of the transformer(s). An 811A project wouldn't
be out of reach in terms of the cost of the tube and a plate
transformer. Ideally i'd like to build something that produces the
full legal limit but I think that would be cost prohibitive and
unwise until I get something smaller under my belt. hi hi

160 meters, T/R switching relay with receiver muting for Drake R-4,
possibly xtal controlled for fixed frequency at 1885KC for example.

That would be swell.
I'm fairly comfortable building HV supplies, etc. but i'm completely
unfamiliar with how to calculate what size variable capacitors to use
for tuning, tank coils, etc.
