I'm using a Diamond GZV4000 (and sometimes a -6000), and that
works well.  I also use a somewhat smaller and lighter unit
when I am on the road- the Samlex 1230 (25A), but that one
gets pretty hot and doesn't seem to be quite as stable.  This
improves a lot if you connect a lead-acid battery in parallel
with the K2.

All of the above are HF-clean, by the way.

Cheers,

You'd be happier to not scrimp on a good power supply.
I have used the Astron 25 SS-25M for years without fail
or hash noise. I think it weighs ~ 4.5 pounds.

I have used lighter weight models like the MFJ 25A MightyLite
and Jetstream JTPS28  in contests and either one would
trip out and shut down under continuous use.

To power any radio (other than matching supply provided by brand
radio) Go with Astron.

Use Astron

You cannot go wrong with Astron.  Being limited in $$, I bought a
Samlex 1223.  I have used the Samlex 1223 with my K2/100 for years
without any problems.  My Samlex 1223 was involved in a bad house fire.
  I had to open it and clean out all the smoke deposits and water.  
After being dried out, it has run FB for three years after the fire.

My K2 was the only HF rig recoverable after the fire.  I cleaned all
the boards with alcohol and distilled water, replaced the melted
buttons and knobs, and replaced the front panel.  It has also run FB
for three years following the fire.  The reason it survived was its kit
construction and operator repairable design.  The only other surviving
radio was a Yaesu VX-5 HT that was in a leather case and found on the
floor after the fire.  Both radios emitted a faint smoke odor upon
their operation for two years after the fire.

Using a robust power supply is important.  Bad designs can itroduce QRM
and cause strange behavior due to the slumping of their output under
load.  It is important to use heavy power cords to your rig for the
same reason.

Small, lightweight and NO rf hash - the Alinco DM-330MV - most excellent.

Volunteer (s) needed to "person" an Elecraft Booth at the Stone Mountain
Hamfest that will be held in Lawrenceville, Georgia (outside Atlanta) on
November 4 and 5, 2006.  Hamfest information at:  http://www.totr-radio.org/

I did this last year and had a ball!  Some of you may remember the "Moon
Pie" give away!  Unfortunately, it looks like I will not be able to be there
this year and am looking for someone (s) who would be willing to "person"
the booth.  I can get all the arrangements made but just won't be there to
enjoy the fun!

Any takers?  Please respond off list via email or give me a call at
404.218.3595 Cellular.  Tnx es 73 -- Don N4HH

Ron, I had one and it was too noisy for me.  Perhaps it was because it was
older ser # of the same model.

I am using a Samlex and an Astron SS-30M.  Both show no noise.
