<DIV>Would tropo ducting be stable enough for a TCP stream to send the video?
I know of that one instance where South Australian TV was ducting through to
Victoria, carrying Underbelly to the chagrin of lawmakers :) But it only
lasted 10 or so minutes, IIRC</DIV>

<DIV><FONT size=2 face=Arial>Thanks Mike</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I am no expert in this field but it seems to me
that your calculations are predicated on a line of sight situation. I am
well aware of the curvature of the earth and understand why the Venzualans
and Italians have something of an advantage here with their high
mountains.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>There is a thing called tropospheric
ducting which, if the conditions are right, turns the atmosphere into a
waveguide and allows signals to propogate over distances greater than line
of site.</FONT></DIV>

<DIV><FONT size=2 face=Arial>The National 2.4 ghz record for VK4OX to ZL1AVZ
is 2,317.5 km which is certainly over the horizon. Now they will most likely
have been using voice or morse at 100 watts however it does illustrate that
UHF signals can propogate over longer distances using tropospheric
ducting.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> </FONT></DIV>
<DIV><FONT size=2 face=Arial>Here's how I envisage a world record could be
set. We would enlist the support of the Elizabeth Amateur Radio Club
who I am hopeful would be interested in assisting.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>At our end we would outfit GHO with an
additional directional antenna (2.4m dish?) off either the North or South
Network. This antenna would have the maximum gain possible and in fact to
keep within the 36db limit we might even have to crank the power output of
the router down a notch or two.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The antenna would be precisely aligned and
point towards Elizabeth, just above the horizon in terms of vertical
alignment.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Over at Elizabeth the Amateur Club has access
to a water tower on which its repeaters etc are located. It also has a
node for Air-stream. You can easily see it on Kettering road in
Elizabeth. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial><A
href="http://www.earc.org.au/on-air/">http://www.earc.org.au/on-air/</A></FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>So they would configure an additional
antenna pointing at us with an attached router hooked into Air
stream. </FONT></DIV>
<DIV><FONT size=2 face=Arial> </FONT></DIV>
<DIV><FONT size=2 face=Arial>It gets better though. Also on the water tower
is a <FONT size=3 face="Times New Roman">2,403.452 mhz beacon with an ERP of
20 dbm transmitter which I think is 100mw. Put it this way. if we can hear
that beacon here in Victoria chances are we can work some wifi dx to
Adelaide.</FONT></FONT></DIV>
<DIV><FONT size=2 face=Arial><FONT size=2
face=Arial></FONT></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The distance between the water tower and GHO is
about 692.5km, enough for the world record.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The idea would be to use off the shelf wifi
gear, unamplified. With that distance we would also break the amplified
record at the same time. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
