Thanks to Roy WN3F for alerting me to this. Tadashi-san has really built some beautiful stuff. Especially impressive to me is his use of the spectrum analyser and two-tone audio tests to look at IMD of the entire transceiver. See video above. FB OM.

1,280 Antennas at 12 GHz -- How Starlink Works

One commenter questioned why we went with the more expensive Starlink system. The simple answer is that it is just better, faster, and more reliable than the alternatives. Many people here are clamoring for this sytem, and they are doing this for a reason. On speed tests I am showing downloads of about 150 Mbps. That is fast. The truth is that my wife is more of an innovator than I am -- she was the one who decided on Starlink.

When we were installing this system, I didn't even know what they meant by "Dishy." I didn't know there were motors in the antenna. And I certainly didn't know about the complicated software and hardware that allow the Dishy antenna to track the Starlink low earth orbit satellites without the use of the motors. The above video explains it all very well.

This is all a great demonstration of what can be done with digital technology, microchips, software and UHF.
