Jim,
Equipment wise, is this reciprocal if you use the array for your receive
measurements?

I think your too close to tell, or just coupling into every thing around
there. Knowing you I am sure you have done every thing right. Try calling
CQ during day light hours and see what signal strengths the Reverse beacons
give you. http://www.reversebeacon.net/main.php
Problem with doing this

I get good F/B on arrays I test, even within a wavelength or two. As long as
the elements are reasonable length (under 1/2 wave) and spacing reasonable,
the pattern should be formed up almost totally by somewhere
Hi, Jim
I'm most suspicious regarding your radial systems:
* Are your radials resonant? For the purposes that you are attempting,
they need to be, in order to maintain the phase relationship between the
driven element and the parasite.
* Are your radials elevated?
* Do your
* Are your radials resonant? For the purposes that you are attempting,
they need to be, in order to maintain the phase relationship between the
driven element and the parasite.
Actually there are three cases that work:
1.) Where a limited size system has radials are exactly resonant
2.) Where
See correction below in RED.
Looks like the Reflector wouldn't pass the EZNEC attachment. I'll have to
forward that in separate e-mails - not on the reflector

Regarding how the RBN works:
You will be re-spotted if you change frequency (more than about 0.1 kHz), or
after 10 minutes.
Note that due to QRN/QRM/QSB, some Skimmers may not hear you the first time
you call. For this type of testing, you might want to call several times in
a row, on the same
