Found this 10GHz setup:

The description from the comment on reddit where I found it was: "The radio feeds a 144mhz signal into that box, which houses the transverter. It's then multiplied up to 10.1ghz, and the output signal travels down that shiny little pipe. The antenna is that horn, and the dish gives it about 13dbi gain"

Found this nicely laid out page of #linux console / ncurses tools. A few were new to me, perhaps also to you? https://kkovacs.eu/cool-but-obscure-unix-tools

I started learning CW! I settled on using the LCWO website (free and open site) and am in equal parts frustrated and yet compelled to keep going. https://lcwo.net/

I set up cross-band repeat on my Kenwood TM-V71A and was able to operate the local repeater from my Baofeng(s) so I call that a successful afternoon. There was only one person on the repeater and he said I sounded "scratchy" which was disappointing, but at least I know how to set it up now.

Playing radio today with my portable tripod (an all-aluminum stand usually used for scene lighting on emergency vehicles). My Comet GP-3 (VHF/UHF) antenna is mounted instead. Tripod is about 12' (3.66m) where the antenna mounts.

I couldn't help but grab this when it came down off the roof at work. We used it for internet for some years before switching to fiber. Now the question is what to do with it. I'd like to use it for long distance mesh networking.

I'm a little disappointed there are still no flying cars, but Computed Axial Lithography 3D Printing looks pretty amazing too.

After grabbing ISS SSTV images a couple weeks ago so I started looking at weather satellites on N2YO.com to see if I could pick up those signals. I noticed that NOAA 15 would be passing over this AM, so I grabbed my scanner and my RTL-SDR (and held a short 2m antenna to it since I don't have a connector). I can't access 1.7GHz but both of these can tune to 137.62 MHz. I was able to hear signal with RTL-SDR set to "Raw IQ" but not sure how to set that on the scanner. What to use to decode?

New engineering manager showed me something nobody else had noticed today - a device we didn't design but might be selling soon comes with a remote to activate a servo motor in its mounting base. "Do you know what frequency that remote operates on?" I said no. Turns out its smack in the middle of 70cm ham band!

Found this page which describes a bunch of sources of interference in the home: https://www.randombio.com/interference.html

Hooked up an old K40 CB antenna to my RTL-SDR (not tuned) and see these bands of interference. Could it be a nearby wifi router? Other ideas?

Does your radio club operate on a repeater? If so, do you have a designated simplex frequency that you all know to use if the repeater is down? If so, why did you choose the frequency you use? If you do not because perhaps your members are geographically distant what is your fallback plan?

Spent some time investigating HAM radio mesh networking yesterday after listening to a podcast by Andre K6AH on the current state of AREDN. Then dug up this video presentation he gave a couple years back which went into detail about actual application. https://youtu.be/sbXllfgbnI8?t=792

I enjoyed acquiring SSTV images from the ISS over the two weekends they ran the event. I kept notes as I tried different methods (I didn't learn about the robot36 app till today which would have made things easier) and posted the images I decoded here: https://www.k3ltc.com/links/iss.html
