[Elecraft] BIZARRE OFFERING FROM MFJ

[Bill Frantz]

I remember the bright yellow glow from the final in my Heathkit 
DX-40 when I forgot to connect the antenna. At least the plate 
didn't melt and the tube still worked.

I had a 100W K3 with no tuner and one of my antennas needed a 
tuner, probably for 30M. I used the T1, with the caveat that I 
would always lower the power when running through it. Well, I 
screwed up one time. I think what I noticed was that as my PSK31 
macro ran, the SWR kept rising.

I think I got the cores hot enough to change their magnetic 
properties. When they cooled off, everything went back to normal.

But as I said, Elecraft equipment tends to survive forays well 
outside their specs.
