Shade definitely can help. I had this happen during a field day a few years

A covered bridge is a wooden structure built across a river or creek
with a roof and enclosed and/or partially enclosed sides used to give
protection from the elements, usually snow or ice. These were fairly
common here in Waterloo County during the 18 hundreds, built by the

There is a specific formula to determine if you are in the near field or far
field and the distance is based on the wavelength to give you a specific
distance from the source antenna. It has to do with a changing phase front (in
the near field) or a constant phase front (in the far field).
Hi Chuck,
I did see your original post and I believe the program that you are
looking for is K2Z by Tony Wells G7IGG. You can find it on the
Elecraft website: http://www.elecraft.com/ . Click on K2 Software.
PA0AKV's e-mail is pa0akv(at)noord.bart.nl (according to QRZ.com)

The hotlinks on the Elecraft website for K2Z are no longer valid it

It is very true that antenna analyzers are affected adversely, without
filtering, in the near field of transmitters such as AM stations.
Here at the research lab, we are about a mile from a directional AM station.
One of the popular antenna analyzers gave swinging SWR meter readings

Hmm, I am not sure what that would mean, an analyzer that can see near field
effects.
The in line analyzers indirectly might show near field effects simply by
being interfered with by strong RF nearby.
Almost anywhere on the boat that is away from structure and conductors will
have the same
My K2 survived the smoke test.
It's not aligned yet, but I can hear and transmit on all bands.

Once the proper values are written into the EEPROM by the CAL PLL and CAL
FIL processes, they should remain stable unless the PLL reference oscillator
frequency changes substantially (similarly the BFO Frequency).
The most important thing to assure accuracy is to carefully set the K2

Hi everyone,
Since everything but the BFO was working I decided to finish wiring the

functions worked perfectly but now the transmitter parts are in the

A second K2/100 should do a fine job in a mobile setting, and think of the
fun you will have building that 2nd one. Oh, yes, I assumed that the first
one would remain at the home station.

U9 should be a 6v regulator, no? 77L06. It's getting 13.8v and
outputting 7.96v in the Alignment and Test Part I. The manual states on
U3, pin 6 should be 6+/-0.25 v. Because of U9 being 7.96, so is pin 6.
Any thoughts?

Thanks for the clarification, John. So I think the analyzer would best
help you determine the impedance match which may be affected by those
various affects and proximities that you refer to. It won't tell you
what your radiation pattern will be. Certainly coupling to nearby
metalic objects
Sorry, user error with a bit of panic I don't know how I did it, but
I installed C10 (bottom of the board) into C38's position. C10 is a 10uf
electrolitic on the output of U9 to ground. That fixed it all, now I
just hope I didn't blow up U3.

Ah, I think I'm alright.

Matt,
You are not incorrect, but I thought I might clarify - the real control over
8R and 8T is done on the control board from the RX and TX outputs from the
microprocessor - which drives the gates of Q3 and Q4, and in turn turns Q1
and Q2 on and off providing the 8R and 8T lines at the correct
John,
Another post explained that the analyzer would give you an idea of how your
antenna is affected with respect to SWR and impedance. If you are
concerned primarily with how your antenna is getting out, I suggest a
field strength meter. A simple one will do the job, but you will probably
