Supplies with big trnasformers, or even small ones carrying high current,
can/will often cause hum on the K2. Best to space them a distance away.
Switchers probably won't induce hum, but might cause in-band birdies by
virtue of their switching frequency and (for some) lack of adequate filtering.

OK .... here's the new program!
Supplies with real transformers can cause hum in the K2
Supplies with switching can cause birdies in the K2
What's the option? No power supply?
No power supply, No hum, No birdies, No problem?
Well, the sensitivity goes to Hell in a handbasket.
The solution?
The new K2-PSQ and K2-PSH
K2-PSQ is a 4 amp power supply to power your K2 with a bit of current to spare.
K2-PSH is a 25 amp power supply to power your K2/100 with a bit of current
to spare.
Both power supplies fit in an enclosure that fits right under your K2 or
K2/100. How do they do it? SMT - the new technology. Brought to you by
the Godzilla PoWer company, Surface Mount Transformers that can deliver up
to 10000 watts of live of power. In conjunction with Elecraft LLC, and
QRP-L, Godzilla has miniaturized their line of very high power supplies to
fit into the Elecraft KAT-100 1.5" enclosure with 99.89776% regulation
(mandated by qrp-l, and several 6's).
Just send the name of your financial institution and a letter from them
with a line of unlimited credit to ..... well, you get the picture!
Ok ..... wife brought the little white pills to calm me down and said she
will let me go back to the shack for some 40M cw in a short while. They
tell me I haven't been the same since Godzilla came out with the 3 db per
hundred feet gain special coax. Guess I never should have ordered that
1000 feet spool!

think ..... and think ...... and think!
