I searched available parts online — but there really aren’t any continuous mechanical variable capacitors around ~10 µF on Amazon, eBay, or typical component suppliers. Mechanical variable capacitors (rotary types)…
There are 1,000 picofarads (pF) in 1 nanofarad (nF).• 1 nF = 1,000 pF• 1 pF = 0.001 nFThis is a straightforward conversion based on the metric system where the…
There **are numerous online references linking AirSpy software-defined radios (SDRs) with software-defined radio use in radio astronomy, both in project guides and community discussions about detecting astronomical signals. Here are…
Yes — a radio telescope reflector can be made from separate hexagonal panels that are not electrically bonded together, provided certain conditions are met. This is actually very common in…
This is a live observation from my new 134cm VLF/SIDs aerial which directly feeds into the computer soundcard.
I asked for help on whether my design and dimensions of the single-cavity hydrogen-line Cavity Filter are correct. https://www.astronomy.me.uk/wp-content/uploads/2026/03/SARA-RTOP-My-Presentation-010326.pdf
