[amsat-bb] IC9700 Update

[Patrick STODDARD (WD9EWK/VA7EWK)]

Hi!

I've had Astron switching power supplies for many years. If they
give off any RF noise/interference, I don't see it on ham bands.
They are quiet. I also have a Powerwerx SS-30DV switching power
supply for operating away from home. The Powerwerx unit is small,
and also has been quiet when used with my ham gear. The only thing
you have to do with the Powerwerx units is to make sure the AC
voltage is properly set on the back - they are normally set for
220V out of the box.

73!
