[Elecraft] KAT3 L10 burned

[Julius Fazekas]

>From the original tuning of the various antennas, in this case three different antennas for 160, 80 and 40. I know the reactance sign from my test equipment at several points in the band.

160 seems to present the most difficult challenge, particularly running during a contest. There are several spots in the band where I keep a very close eye on the PS current meter, and back off on the power to play it safe. Periodic retuning using the KAT3 helps, but the problem is at the antenna and I've not determined a satisfactory broadband fix yet...
