coax jumpers with poor shield contact at one or both ends. Try another
cable if you haven't already.

Any thoughts on choosing the Cushcraft over the Hy-Gain for a vertical?

I have an apartment on the top floor of a 10-story building with a small
roof area accessible and restrictions on antenna size. I asked for
advice here about antennas, and got a lot of suggestions and help, so I
thought I would post my results.

Since getting on the air from Israel I notice an interesting noise on
the bands 7 and 10 mHz and to a lesser extent on 14 mHz. It is a
wideband 'schmutz' (technical term) which can take from 10 to 50 or 100
kHz. Its amplitude drops of gradually as you move away from the center.
It reaches S9
Thanks to all who responded. The Chinese radar seems to fit what I hear
best. I'll try to null it with my Pixel Loop (which, by the way, is a
great, quiet receive-only antenna:

I am pretty sure that there is no way to tell the K3 to bypass or enable
the ATU in a macro command except by simulating the button press. Am I
correct?
What I want to do is make my amplifier on and amplifier off macros
bypass the ATU when the amp is on but enable it when the K3 is directly
MN023;MP001;MN255;
should enable the KAT3 and MN023;MP000;MN255; should bypass the
KAT3. Note I have not verified the specific MP values.

Did you check D9 and other components on the RF board that provide the
VRFDET signal?
How did you check VRFDET, VALC, and VPWR on the control board if the
transmit power is unstable?

I think you should go over all the solder joints on the control board.
Just heat them up and apply a tiny bit of solder. Wait till it flows. It
is not a good solution to leave out the screws, because oxidation may
ultimately make the bad solder joints fail even when the board is not
stressed.
I agree. I would just add that if you use an inverted L or V configuration, be
sure the included angle is 90 degrees or greater. Otherwise there will be some
cancellation of radiation from the two legs. As a thought experiment, consider
what would happen if you reduced the angle to 0. That
I've been quiet lately, working on getting back on the air at my new
QTH. But I am thinking about the future.
The K3 is still a great transceiver. For my purposes, there is nothing
better out there for a reasonable price. But the competition isn't
sitting still. And as everybody knows, there
on.
My station is set up and my license renewed, but the bureaucracy is
grinding very slowly on the non-ionizing radiation permit that I need
to put up my antenna.

Non-ionizing radiation is electromagnetic radiation, like HF - UHF radio
waves, that doesn't have enough energy to knock electrons off of atoms.
X-rays, Gamma rays, ultraviolet light, etc., is ionizing radiation. We
know ionizing radiation can be dangerous.
Some people think that non-ionizing
