Re: [Amps] Laminated core toroids

[Jim <jimw7ry@gmail.com>]

NEVER use a toriord for a plate inductor. Too hard to tame and too many 
wierd resonences. Especially on 160 meters.
Use a coil. You don't need very large wire for 160. Been there done 
that. Never got it to work.
160 meter torrid would get hot and smoke on 10 meters. Even with it 
shorted out.
