Have just started listening on 10 GHz using web SDR for the Qatar Oscar 100 geostationary satellite. Hope that someday I will be able to come up on 10 GHz! But the uplink on QO 100 is only 2.4 GHz. 73s from India.
10 ghz is too high to take advantage of natural tropospheric reflections. Those reflections happen on 432 mhz and even as low as 130 mhz pretty much every single day unless the weather is garbage, or the sun is on the other side of the planet. In fact, with just 50 to 100 watts, you can pretty much do up to 500 miles if both sides are running sensitive RX (band pass filters) and have constructive high gain style antennas, or antenna arrays (yagis/dish/etc..).
Thanks for posting this Hayden 👍
Thanks Ape
Fascinating. Final comment from Rex is gold. VK8MC
Beautiful.
This is some really high tech stuff!
DX-pedition with a difference
The work on microwave bands especially 10GHz which Rex & the other guys have done is nothing short of fantastic

Dear lord, 725W at 10GHz? I hope he's already had children :)
LOL

Yes, I already have 3 adult offspring :)

I disagree. Rex (the speaker) has the current Australian record on 10 GHz from VK7 to VK6, a distance of 1600+ miles
At a distance of 4115Km the curvature of the earth will give a 1283.37 km difference in height between the two points !!!
Just saying.
Ducting.
