My power supply solution

[Edward R Cole]

First off PS are widely available and there is no incentive for
Elecraft to expend design effort.  IF they decided to offer one it
would likely be a repackaged PS from a vendor.  And that might be
desirable to many who want a nice visually integrated station (aka "pretty").

MY station runs 18 bands from 600m thru 9cm at home.  I power the 12v
equipment with a 50A Astron rack-mounted supply.  It feeds thru about
12-foot of #4 welding cable to the 30A main Buss fuse at the
distribution terminal strip.

The 28v equipment runs from two supplies: a Motorola CCS 500w
repeater supply and a 8A adjustable 22-30v supply (for relays,
etc.).  13.8v drops to about 13.3v under 25A load.

MY 6m QRO SSPA runs from a HP 50v-50A switching supply (230vac
input).  And my 2m-8877 runs on a 4kV 1.5A modified commercial supply.

I have a B&K 0-30v 3A bench supply and 0-15v Astron VS-35M on the bench.

The dish runs with a 28v 50A military surplus PS.

Really want Elecraft working on high-tech projects not simple AC/DC
voltage converters (what a PS is afterall).   I think a reasonable
solution is an empty Elecraft cabinet (say the P3 with plain front
panel) which anyone can install the PS of their choice for their
"station beautiful" (smile).

I am looking forward to the KX3-2M module and the KX3EXREF.  I will
also be interested in looking at the KXPA-100 for mobile use.  Too
many neat ideas for Wayne and Eric to explore to waste on PS design (IMHO).
