[Elecraft] Very High SWR on all bands; K3 #6957

[Fred Jensen]

Yep.  Dummy load resistors have a finite lifetime, it seems.  I had been 
lugging around a "Benton Harbor Paint Can" full of mineral oil from move 
to move for decades.  I first filled it in 1968 in Houston TX.<see 
below>  Not long ago, while using it as a port terminator on a duplexer, 
the port isolation was nowhere near what it should be.  Ohmmeter said 
the Cantenna had become a 97 ohm dummy load.

<below> Purchasing 4 qt bottles of Squibb Mineral Oil at the local 
supermarket ...

HER: I can't sell you this oil.
ME:  Why not?
HER: It's Sunday.
ME:  I'm over 21.
HER: Are you going to drink all of it?
ME:  What?
HER: If you are, it's medicine and I can sell it to you.
ME:  Yes.
HER: That'll be six ninety seven and thanks for shopping at Weingartens.
