Just a note to add some info to Charles' request for listener reports.
The latest version of the K2 Beacon Monster software is designed for use in
attended mode, as well as unattended mode. Attended mode is probably the
only allowable HF beacon mode for most hams in most countries due to licence
restrictions.
Because attended mode means that the beacon may be down at random times (e.g
when the operator goes to bed!), the software frequently uploads a status
page to a designated website. The page gives details of the time of next
transmission, the format of the transmission, and carrier power sequence
information. It also gives the equipment list and locator info. All this
stuff is compiled automatically from the beacon settings.
The software takes advantage of the K2's accessory set that allows dual
antenna switching and so Charles is able to use the beacon to transmit on
two different antennas so helping do antenna comparisons.
Lastly, to keep the beacon transmission times reasonably accurate, it makes
use of Internet time sources to help keep transmission within a few seconds
off the time stated on the status page.
See http://www.tinyurl.com/6oh59 for details of the message and the
status of beacon.

Subject: [Elecraft] EH Antenna test using K2
To All,
Tony Wells, G7IGG <[EMAIL PROTECTED]> and I are testing an EH
antenna vs a normal 1/4 wave dipole and we need some signal reports.
The test is using my K2 and Tony's Beacon Monster software. I am
operating a manually controlled beacon on 14.102 MHz. The software times
the beacon and commands the K2 to send a brief message on one antenna then
switches antennas and sends on the other. See
http://www.tinyurl.com/6oh59 for details of the message and the status
of beacon.
This is an example of what you can do with the K2.
Please send signal reports to me. The best way to measure the signal
report is to use Spectrogram, MixW or Spectran to measure the signal
strength. If you can record a .wav file with the AGC off, please send it
and I can analyze it with Spectrogram.
Locally and in US, preliminary results indicate the 1/4 wave dipole is 3
to 6 dB stronger than that from the EH antenna. I have some reports from
European stations that the EH is 3 to 6 dB stronger, but I have a very
small sample; that's why I need more reports. The old adage that a
vertical antenna radiates equally poorly in all directions may not be
true. These antenna may have some directivity.
