Boy, is my face red!!!
Thanks to KO9Y, W7NI and AA5BT for pointing out the finer points of
Part 97 to me - I should have known better. I am sorry and it won't
happen again.
(p.s....did I say WPX and Croatia?...I meant SS and California...)

Re: POWER !
Thanks to the many who sent personal replies, some mentioned calls
of Europeans who are head-and-shoulders above me in strength, the
bottom line however is the actual RESULTS at the end of the day.
Check the magazines over the last ten, twenty or more years.
CONSISTENCY counts for something you know.
For the record, I run a TH7 at about 40 feet with a 40-2CD stacked
about 10 feet higher, and an 80 sloper to the West. For CQWW I have
sometimes "borrowed" a neighbouring tree as an additional wire support.
The *LOCATION* is on a small hill with sloping ground from West thru`
North East so favouring USA and Japan.
The station, in my opinion, is well engineered within the real estate,
(or lack of it) that I have. Hard-line (ANDREW Heliax) is used on all
external feeders with quality connectors and other attention to detail.
Maybe that strategic bit between the headphones has something to do
with it too.

Subject: Connecting Cluster to CT/Log+etc thru internet??
Message-ID: <Pine.SOL.3.91.960402172949.14403A-100000@granby>
Hallo there,
I was just wondering whether anybody has achieved with success
to connect packetcluster to a logging program with packetcluster support
(eg K1EA/LogPlus etc) but WITHOUT using a TNC and radio link but a MODEM and
THE NET. Why I am asking?? NOT all countries have cluster support on VHF.
A friend has suggested using 2 computers (one as the logging
computer and one acting as a "TNC" thru some sort of TCP/IP software
(JNOS?) with telneting to an ampr.org server. Has anybody done something
like this before? If so could you give me some details?
I am aware of OH2BUA WEBcluster page but that will require a
separate http browser but I cannot think of a way of feeding the DX spots to
the logging program automatically.
Please reply directly to me, and I can summarise for the
reflector (if there is interest).

About the year 2005 or so, CW as a test for an amateur license will probably
be gone, world wide, if things go as they might at WARC 99. Only hope is
CW tests will be replaced by some technical tests with real teeth to act as
a way to keep our bands from becoming as did the CB bands, completely lawless
and world wide, as in Indonesia now.

Subject: S Units
Message-ID: <n1383672705.6572@maca.sarnoff.com>
RE>S Units 4/2/96
Each S unit is doubling of the detected voltage. In a receiver, the meter is
driven
from the Automatic Gain Control system. This system has a detector (or
detectors)
that sample the signal level. The voltage is amplified and used to control
the gain in
stages ahead of the detector ( the RF & IF ). The voltage is also used to
drive the
meter marked S-units. Since, the relationship between this Vagc and actual
signal
levels is not simple (due mostlyto non-linearity in control voltage versus
gain),
the meter scale & amp must be calibrated. The calibration is usually accurate
at
only one or two points on its scale. Some modern receivers carefully derive
the meter drive from the Vagc by a more complex scheme such a logarithmic
amp or even a digital look-up table to offer a better approximation. The
detector,
though, is subject to signals other than just the desired. Further, the
desired is not
a steady sinusoidal waveform. The meter is mostly a useful guage to see how
the
receiver is reacting as it processes signals with its automatic gain controls.
If you can shut off the AGC system and are receiving a steady tone, you can
put an AC volt meter on the speaker. You might have to reduce the RF gain
manually
and introduce attenuation so as to be in a region of low distortion of the
audio.
Once, this is set up, a doubling of voltage is a change of one S-unit. Which
is a
four times change in power received. A 3db change in voltage is a 6db change
in power. This simply because, power changes as the square of the voltage.
TTFN.

Hi Bill,
In a message dated 96-04-01 13:07:32 EST, you write:

>I beg to differ. I believe that S-meter circuits are calibrated in terms

That's a common misconception Bill. Beg all you want, one dB of voltage
change is 1 dB of power change, look at the formulas! A 3 dB pad provides a 3
dB voltage, current and power loss.
S meters show larger than expected increases because 6 dB is NOT an S unit.
That figure never was an industry wide standard, and certainly isn't today.
Almost every rig is 3 to four dB per S unit when properly aligned. And even
the dB end of their scales are usually wrong.
Remember three dB is three dB, with either voltage, current or power. It's
one of those rules that work funny but save headaches.
