[Elecraft] power supply

Fri Nov 1 12:16:00 2002

Switchers are smaller and lighter weight.  If you don't need to travel with
it (contest or DXpedtions) and have room in your shack, then the linear type
is great.

I've had the best results with Astron switchers ... and their linear
supplies are great, too.
