Thanks!  I was surprized, because I think this supply was the one sold with
the flex-3000, so I would have expected better.

	It certainly won't hurt but I've found those measures hit and miss.
They are based in sound engineering but that RF sure has a way of getting
past filters through such things as the chassis ground or the microphone and
speaker cables at times.

	One might have to put a big toroid on each lead of the power supply
as well as each side of the AC power cord.

	One way to make a switcher real cheap is to eliminate all those
heavy expensive toroids and shunt capacitors. The supply will run a computer
just fine and be very light to carry around but can double as an all-band
transmitter. I am proposing a new certificate. It's the WACPSAWAB or Worked
All Continents on Power supply At Once on All Bands.  Good luck.
