Hi Ed,
It's a Radio Shack 13.5 volt, 1-amp supply. I was using it mainly
for receive and test transmitting, up to about 2 or 3 watts, for
which it worked great with the K1.
For what it's worth, the supply has a good long cord, two of them
actually, about 6 feet of cord from the outlet to the supply itself,
then another 6 feet from the power supply to the radio. The supply
was never anywhere near the K2. However, my work bench is a pretty
busy place, so there is a lot of other electrical equipment within 2
or 3 feet of the radio.
On the other hand, I built my K2 with the magnetic VCO shield option
right from the start, so I never bothered to instal L30. So I'm not
sure if the problem was magnetic interference. I suspect that the
the DC coming out of the power supply isn't as clean as I expected.
Anyhow, running it off some batteries did seem to clear up the
receive 100%. To be sure though, I'm having another good look at the
K2 to make sure I didn't miss or mess up any of the RF chokes.

Just so we know so we can using it, What was the power supply you
were using
that caused the problem?
Thanks

Thank you everybody for pointing out the very obvious source of my
problem. I had read about what can happen with low quality power
supplies.
