[Elecraft] KPA-1500 on 160

[Pete Smith N4ZR]

Bingo.  Into my Cantenna no problem all the way up to 1500W.  I also 
noticed during the antenna tests that my amp heated up very rapidly to 
levels not seen before (over 70C).  I had expected lower efficiency on 
160, so I'll need to watch it.  I was temporarily driving my Carolina 
Windom, and of course it's not intended for use on 160.  My 160M 
inverted-L, with a nice low SWR,  is not yet hooked up, pending the last 
lawn-mowing of the fall on Monday.
