[Elecraft] K2 current draw

Sat Nov 29 22:02:01 2003

Still having current draw issues with the new K2 and getting ready to check
things over again, but thought I would add this incase the "more
knowledgable" have some input.

At 5 watts the rig draws between 2.3 and 2.7 amps fom 20 to 10 meters but
jumps up to 5.1 amps on 40 and 80. I am going back again to look at the
toroids and I rewound  T1 and T2 again today to make sure there was nothing
touching. Any thing else I should check for?

73,
