[Elecraft] Need to select a dummy load for K3 TX calibration...(advice?)

[Dave New, N8SBE]

"I don't like the idea of a can of oil sitting in the house," -- in
particular, if you don't know what kind of oil might be lurking in that
old Cantenna.  Note that prior to the "A" suffix models, Heath
recommended transformer oil, and had no warnings against using oils that
contained PCBs.  After PCBs were outlawed in the US, Heath changed their
recommendation to mineral oil, and included a warning against the use of
transformer oil of unknown composition.

So, if you come across a vintage Cantenna at a ham fest, what do you
think might be in it?  If it's the old style with the little 'house' on
top, I'd steer clear of it.  The Cantenna should be disposed of, in
accordance with federal law, and under no circumstances should be opened
by untrained and unprotected personnel.  Considering that most of these
Cantennas leak around the screws on the lid, I'd be very leery of any of
the 'first edition' Cantennas.  The new ones, with the spiffy Red/Black
logos, should be OK, but if you have any doubt, pass it by.

73,
