Howdy! Tom,

Those Sat TV birds must have a real powerful semiconductor device.

It's a wonder they can keep their battery charged at the increased
power level to keep the bird from going dead.

I was told by a civilian radio tech who worked for the Corps of
Engineers there were high power transistors in use in some commercial
RF gear.

I'd hate to have to buy one of those Xsistors to replace one that died.
