[TenTec] Switching Power Supplies

[aa4nn]

Perhaps I am just lucky, using from time to time,
switchers from Astron, MFJ, and Jetstream.
Never heard a problem, but then I never did scan
from top to bottom all of the amateur bands
looking for trouble.  But, on DXpeditions, no
known problems to other stations nearby.
