Most of the PCBs these days have green colour on both sides, often with surface mount devices mounted on both sides of the PCB. The green PCBs are typically made from a core of fiberglass reinforced with epoxy resin. https://t.co/3X6Hb2Wn5E

As part of my daily morning propagation checks, I had a look at Reverse Beacon Network at around 5:15 am (11:45 PM UTC). I was surprised to see six spots from VU2GSM on 160m, on 1824 kHz. MM0ZBH at 5129 miles the farthest. https://t.co/HqkLiHdfkN 28 dB SNR at DL8LAS (4581 miles)!

Really interesting!
How do astronauts unwind in space? Watch how they practice some of their favorite hobbies 250 miles above Earth.

I have been hearing my friends giving spectrum spread reports when other friends were testing homebrew linear amplifiers. Yesterday VU2MIE, who is also using an FT-710 radio told me how to check it and here it is: https://t.co/IyvfM84sEi

Nice to hear the sound of MSK144 on 6m! May be it will work even if you keep the audio muted in the radio as it is the computer which does the work! 73 Jon, VU2JO
My spouse says FT8 has an annoying sound, but MSK144 takes it to a new level.

Proud to see 1.0 GHz, 64-bit dual-core processor DHRUV64. Wish I will be able to use a laptop/desktop powered by DHRUV64 or may be Dhanush+ in the near future. As of now it seems it is meant only for embedded applications.
DHRUV64: India’s First 1.0 GHz, 64-bit dual-core Microprocessor 💠 DHRUV64 is India’s first homegrown 1.0 GHz, 64-bit dual-core microprocessor, strengthening the indigenous processor pipeline. 💠 National Programmes like Digital India RISC-V support the design, testing and

True multi-tasking in ham radio and more! 73 Jon, VU2JO
This is about all the #hamradio I can handle at once. But a lot of fun! Operating 6 & 10m MSK144 on Saturday morning during the peak of Geminids for the HamSCI Meteor Scatter event. Also monitoring FM Simplex, APRS, and learning a new camera. Geeking it up good here in EM60!
