what would be the parameters for the toroid , for say , 8 or 10 amps ,
other than the size to accomodate the required wire size.???
Type 61 ferrite should work on 160-10 meters. I would wind enough turns to get
a reactance equal to at least 5 or 10x the input impedance of the amp at 160
meters. Amidon FT-240-61 is 2.4" in diameter, so it should be big enough. I
have used their R61-050-750 1/2" dia. x 7.5" ferrite rods successfully. Type 61
is speced for 0.2-15 MHz but works fine in this application at 28 MHz.
