I have made thousands of QSOs using the Powerwerx supply powering both a K3S
and a KAT500.

Is there a problem using the Powerwerx to power both the K3S *and *the
KAT500, or would I need a second Powerwerx?

Whether or not you hear a noise source depends on the nature of THAT
source, in what freque

If the Astron ain't broke keep it. There would have to be a real good
reason, like parts becoming unobtainable, for me to consider getting rid
of my Astron. If they break they are dead simple to diagnose and fix and
no chance of making noise like a switcher.

The K3/K3S draws peak current on transmit, and is generally greatest on
the higher bands (especially 6M) where efficiency of the output stage is
lower. The KAT500 draws max current when tuning. The rest of the time it
draws very little current. In general, any PSU that will run the radio
will a
Looking at the specs, the K3s could draw up to 25 amps max, the KAT500 could
draw up to 1 amp max and the Powerwerx supply is rated at 25 amps continuous
duty. So It "may" be ok. That would depend on how long you hold the
key down or transmit rtty.
You can get the Powerwerx unit that

I have been using that Powerwerx power supply since before Elecraft started
listing them on their web page and it is a good, quiet power supply. I use a
big linear power supply at home and the Powerwerx unit for portable operations
since it is a good compact supply. I got one for my newly licens

Why would you change out an Astron RS35M? Unless you need to
make the K3 station portable where the weight and size of the
Astron is an issue, the RS35M will be both much more quiet and
much more reliable than any switcher.
Even
Well, here I am packing my bags for a trip to VP2M. I think I will
leave my RM35 home and take along the power werk switcher. I'll tolerate
the few birdies I hear from the switcher for the difference in
size/weight. The answer to the question really depends on your situation.

ANY switching power supply is a potential noise source, and even the
best can be heard in antennas that are close enough to it. The one
Elecraft sells is pretty quiet, but I heard

I am using a standard linear power supply with my new K3S.
