Very happy with my Powerwerx SPS-30DM. Small, quiet fan when it comes
on, RF-clean. I power a K2/100 and K2/10, plus a few station accessories.
Also recommend Powerwerx for Anderson Power Poles and accessories. Very
nice company to do business with.

Hello to the list from a first-time poster.
I have a KX3, and have a KXPA100 amplifier on order. I see that my 20A
Tripp-Lite linear power supply isn't sufficient to power both of
these, so I'm researching other supplies.
Astron seems to be the gold standard, but I also see some MFJ
supplies. The 3045MV is a 30A linear supply, and looks good from the
specs. Any opinions on this one?
MFJ also has the 4245 45A switching supply, and the DX Engineering
catalog says, "No RF hash? These power supplies are clean!"
Are they really clean? I don't want ANY hash spoiling my quiet
location, and will avoid any switching supply that creates receive
noise. Does anyone have experience with this line of MFJ switching
supplies?
What about the Astron ASR-SS-30M 30A switching supply. Quiet or noisy?
Should I even consider a switching supply, or stick with a linear
model? The Astron ASR-RS-35M looks good, albeit more expensive than
the MFJ 3045MV.
Thanks for any information.
