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

[David Orman]

Having the Alinco DM-330FX, and the PX3, one thing I want to make sure
people understand is do not expect a 'clean' panadapter display with one of
these Alinco PSUs. You can definitely shift the noise out of a SSB
transmission, for example, but you'll still see it on the display. It was
frustrating enough to me I picked up a linear PSU so spotting signals on
the PX3 wasn't as much of a challenge. Not sure how this other PSU compares
in this regard - but it's something to consider - perhaps someone with the
PSU Elecraft is selling can chime in regarding this.
