As Morse speeds up, you stop relying on individual dots and dashes and begin recognizing common combinations of letters. Faster still and you are mainly hearing word stems and suffixes. The faster the information comes at you, the less impo

Yes, it is real time, but due to interrupts you have to manage critical sections with cli() and sei() and your time base is a 16.000 MHz crystal. Most instructions for ATmega and ATtiny execute in 1 clock cycle so writing deterministic, tim

Amateur radio is a series of narrow regulatory carve-outs of the radio spectrum for the public good, somewhat like a national park. It has existed since the discovery of radio itself. RF is now a mature formal engineering discipline, but th

Judging by amateur radio subreddits, there is significant crossover interest in this among the prepper and mutual aid community. Rhetorically speaking, what does one do with the fox once it's caught? In particular one experimenting wit

My fear would be Helium and rightwing extremist groups. Currently happy to have the encrypted P25 users on the wrong side of part 97.

It's not to trim the BOM, it's because electric vehicles emit copious amounts of interference. It is easier to drop AM radio than suppress the RFI. https://www.nytimes.com/2022/12/10/business/me

I empathize especially with the author's account of "covid nose." For me, Coca Cola now tastes like patchouli. When I say that out loud, it's easier for others to believe I'm simply a hypochondriac, or that I'v

I believe you're thinking of the ISM bands - problematic chunks of the spectrum that are given over to industrial, scientific and medical technologies that emit RF by design. The FCC allows a bit of part 15 free-market anarchy on these

The silver particles in the film aren't very transparent and you can see this for yourself with a microscope. All tonal representations of B&W film, whether a scan or traditional enlargement, depend on limitations of resolving powe

That's a fair question. The time slots I called out above are occupied by learners in the CWops academy. The density of transmissions can be so high that the waterfall resemble the opening to the Matrix. But clearly demographics are st

And if you want to hear what morse telegraphy sounds like in 2022, you're in luck because it's still alive and well. Simply tune your shortwave radio to 7.028-7.045 or 14.028-14.045 MHz every Wednesday between 1300-1400z & 190

I share your concerns. I created a dedicated-purpose Microsoft account by following Mojang's official migration link. The process went smoothly and I have not been asked for a phone number. I am using Fastmail with a custom domain and

Background noise - that's one way to put it! The path loss is around 250 dB, so a practical amateur moonbounce station makes use of a very powerful RF amplifier feeding an array of yagi antennas, all mounted on an altitude/azimuth

In a way you are describing state of the art robotic arms, but computer vision in that domain is less about economizing and more about coping with everyday materials and objects that are difficult to characterize. The OP is coming from the
