New Radio Transmission Technology Requires No Power at All:

by
1w ago
A team of engineers developed a new radio transmission technique that seemingly doesn't require any power. All data transmission requires power, because the transmission itself -- whether that is radio, visible light, or sound -- carries energy. Without a power source, that energy would be "free" and that would violate the second law of thermodynamics. But that energy doesn't necessarily need to come from the transmitter. In many cases, such as when transmitters need to be small and portable, it is very beneficial to reduce or eliminate their power consumption. Backscatter technology already a ..read more

CWvox: A Simple Device That Converts Voice Commands Into Morse Code Keying:

by

While most of us associate Morse code with old-timey telegraphs, it is still in use today. The benefits now are the same as they were a hundred and fifty years ago: it is an incredibly resilient way to encode information that works with a variety of different transmission methods. But what if you have trouble operating a standard Morse code key? This CWvox device, designed by Kevin Loughin (AKA KB9RLW), translates voice commands into Morse code keying. CWvox could be useful for people with disabilities and for people who have trouble getting Morse code timing right. Morse code relies on tone l ..read more

Wow! Sunspot numbers up, geomagnetic disturbances down. What could be better? Okay, maybe Solar Cycle 19, but that was 66 years ago and by far the all-time largest. But this is now, we are in Solar Cycle 25, and this sunspot cycle is emerging better than the consensus forecast. It is predicted to peak about 30 months from now in Summer 2025. Solar cycles tend to ramp up faster than they decline, so we look forward to great HF propagation for years to come ..read more
