10GHz contest time!

#hamRadio #microwaves

Came across this beautiful microwave link station in #norway, a site which operates in a very special way: the signal is aimed towards a reflector in the mountains and from there it is bounced towards its destination 📡👌🏻

It’s not uncommon to do this, but it’s the first time I’ve ever seen one, real life 😃

While visiting sites like this, it’s always a good idea to look at the installation - in this case the waveguide feeds, the dimensions of which reveal the operating frequency area, likely between 8-12GHz.

Hah. Apparently I'm the #waveguide person these days.

"Hey I have these two large waveguide dummy loads, do you want them?"
And here they are.

Mostly a CW op.

I'm in the San Francisco area. 🌉

This last week I have been trying to buy a new microwave, a new couch, and a new bed base. The choice is overwhelming, the various online reviews and "advice" confusing and contradictory, and I am more unsure than ever. This is what comes of overthinking things. A more sensible person, no doubt, would march into the first furniture shop and first appliance shop in their area, jump around on a few items and grab something there and then. My tendency to want to know that I have The Best (within my budget) is my undoing. Aargh.

Imaging Cygnus A at 8.45 GHz with ATA
https://destevez.net/2021/08/imaging-cygnus-a-at-8-45-ghz-with-ata/

Near the end of July, I decided to perform more interferometric observations of Cygnus A at a higher frequency, in order to obtain better resolution. I chose a frequency of 8.45 GHz because it is usually a band clean of interference (since it is allocated to deep space communications)
