[Elecraft] New 30A power supply on Elecraft order form

[Sverre Holm (LA3ZA)]

I'm sure it is right that no switcher is 100% noise-free. But some of them
have a means to change the switch frequency. That could be a way to help
out, if the noise happens to fall on a particularly interesting frequency. 

I have two of them, one is an Alinco DM-330MV (32 Amps) and another is an
unknown-brand Chinese one.  I have only had to use this feature on 160m. I
have ladder line directly into the shack, so I may more sensitive to this
kind of noise than if I had a coax feed.
