Very "noisy" day for 20 m 14.230 MHz SSTV images reception in Metro Vancouver today. First image arrived at 7 AM local and last one decoded at 6:30 PM local. Using MLA-30+ loop antenna, SDRplay RSPduo tuner (also running 20 m WSPR decodes). @K3TripleR @DustinFinn @N4JAW

Mating call of the wire...

Do you call out on 146.52 MHz before or after you do a #POTA activation? youtube.com/shorts/3lWCNSr…

Globus INK, a Soviet-era mechanical navigation system used in spaceflight. It served as an electromechanical analog computer to show a spacecraft's real-time position over Earth. It relied on an intricate system of gears, cams, and differentials rather than digital circuits.

Why not?! Today I RF’ed around and made a loaded 60m vertical with the new Hydra from @ham_coffee and an extra WRC Sporty 40. It’s about 33 feet of speaker wire. #LeaveNoBandBehind #HamRadio

There's an new ARISS SSTV event on the drawing board. In a few weeks time, the ARISS radios on the ISS will transmit Series 31 images on 70 CM. Everything we know so far is in the graphic. Stay tuned for updates.

2 METERS is open here in the South of the US! Just worked KE5WJK in United States Of America 🇺🇸 (Gridsquare: EM31VV / distance: 273.1 mi) on 2m using FM #hamr #cloudlog

I never would have guessed I would be camping in March with 80 degree weather in Wyoming..... Off-grid radio operations are going on now.

Did You Know There’s a USB-A Connector Colour Coding Scheme Have you ever looked at the USB ports on your laptop and wondered why some are blue, some are black, and others are bright orange? It’s not just a design choice—it’s a performance indication. The colour of that little plastic insert (the "tongue") is a standardized (though sometimes flexible) shorthand for what that port can actually do. Understanding these colours can save you from the frustration of slow data transfers or "slow charging" warnings. Here is a quick guide to decoding your tech: ⚪ White (USB 1.x) The original standard. These are mostly "legacy" now, offering speeds up to 12 Mbps. Fine for a keyboard or mouse, but painful for moving files. ⚫ Black (USB 2.0 / Hi-Speed) The most common port for many years. It supports up to 480 Mbps. While much faster than white, it’s still the bottleneck for modern external hard drives. 🔵 Blue (USB 3.0 / SuperSpeed) This signaled a massive leap. Blue indicates 5 Gbps transfer speeds. If you are moving photos or videos, always look for the blue port first. 🔵 Teal/Light Blue (USB 3.1 Gen 2) Often confused with standard blue, this variant supports 10 Gbps. It’s essentially "SuperSpeed+" and is becoming the gold standard for high-performance USB-A. 🔴 Red or Orange (High-Power / Sleep-and-Charge) These colors usually indicate a high-current port. These are designed to charge devices faster or remain powered even when your computer is in sleep mode. They often support 10 Gbps or higher. 🟡 Yellow (Always-On) Similar to red/orange, yellow ports are typically "Always-On." You can plug your phone in to charge while your laptop lid is closed and it's tucked in your bag. 💡 The Pro-Tip: Manufacturers don't always follow the rules. Some brands use proprietary colors (like Razer’s green or Kraft’s purple). When in doubt, look for the SS (SuperSpeed) logo next to the port. Why does this matter for your workflow? Plugging a high-speed SSD into a black USB 2.0 port is like putting a speed limiter on a Ferrari. Match your colors, and you’ll match your potential. #usb #usbconnectors #usbcolours #connectivity #communications #electronicsnotes

Seeing a pattern here..

As Mrs. Doubtfire might say #amateurradio #hamradio #hfbands were "Wicked, Wicked, Wicked" due to #geomagneticstorm but at least I could test recent #km4cft 9:1 unun build & #randomwire with @Youkits #hb1b into ATU-10 Autotuner on a beautiful 1st full day of Spring.
