Hiya, Folks-
Does anybody know if there is a PED data file that will emulate the ARRL
DX contest from the DX side?
(On a side note, does anybody have a source for those "World's Greatest
XYL" certificates? She puts up with a lot during those CONTEST weekends).
Please reply via e-mail to save bandwidth.
Thanks,
Sean KF9PL (for just a bit longer)
Elkhart, IN USA

Several others have responded with suggestions about .01 caps, etc, but I
would suggest you think about why RF in such large amounts is getting into
your supply in the first place. I suspect you have a serious unbalance in
your antenna system that is allowing RF to flow on the outside of your coax.
This usually shows up as "hot" mikes, chassis, etc. The easiest fix is
usually a current-type balun in the coax near the antenna. The second easiest
fix is to determine why the antenna is unbalanced in the first place. Often
it's due to the physical position of the antenna with respect to surrounding
objects.
Whatever the cause, all that RF running around your shack is being pretty much
wasted. RF is expensive to generate - don't waste it by heating up your power
supply components.

Hi Doug,
Well, I'm in the same boat as you. I will not be working any
contests this weekend because I will be spending a good portion of both
days at my place of employment (which, after all, does pay better than
contesting).
I gotta say that I was a little depressed about working through the
second weekend in a row, until you posted your message. Correct me if I
am wrong, but doesn't this now mean that I will be tied with you for
first place in the SNO category? (SNO => Single NonOperator) After all
these years, who would have thought it possible? Now all I have to do is
figure out how to win in that category. (Perhaps I have a moral victory
of sorts - because I didn't use low power and you didn't use high power!)
