I have a 66' (20m-ish) center fed dipole at 6 feet off the ground in my back
yard. The ATU in my KX1 reads P 0.3 and r9.9 at 7090 khz. This doesn't

Hello,
I have a few things I need to do before I head out to the Appalachian Trail
for the last time in 2007.
I will try to be on the air around 7.033 @ 16:00 UTC.

I will pack up and hike out at 18:00 UTC. If the QSO's are still coming in I
Very interesting thread indeed.
My activities on 50MHz primarily take place on dxpeditions, limited to
just six meters. I have often wondered about setting up a second antenna,
spaced several wavelengths away from the primary ant, to try diversity
reception on terrestrial E and F2 propagation.
Check the pitch setting for RTTY. Mine had default of 915 (or some
similar frequency) for the mark. Adjust it using the same method as
CW pitch.

Such a low dipole will normally have, at its center, an impedance in the
general range of 4-j60 ohms at 7 MHz, so the r value you're seeing doesn't
seem surprising.
For all practical purposes it's on the ground and the earth has a very
large effect on its impedance and its resonant frequency. In

With the current situation - in the sunspot cycle low point, that may be
as good as it gets.
Your PW-1 antenna may perform OK on 30 meters and above, but on the
lower bands it simply does not have adequate capture area to be
effective (the same is true of most any small antenna).

The TX EQ is kind of an audio shaper. Lyle can describe it better than I.
But I find I can taylor the audio characteristics as desired. Cutting the

You have the correct part. The 82 in my kit was also marked 820.
