VLF Radio Detection of SIDs (Very low Frequency detection of Sudden Ionospheric Disturbances)
Current state of construction of John Berman VLF/SID receiver and aerial system 13/2/2026
I’ve discovered following works with Spectrum Lab software on my Dell M6800 laptop: Plug audio cable into microphone socket on Dell M6800. Select line in rather than microphone when pop-up…

Two successive massive complex SIDs today 1/2/2026, representing a sequence of multiple solar flares arriving at Earth
Just to finish off my posts on sudden ionospheric disturbances, there were two massive complex ones closely following on from each other today, representing a series of solar flares hitting…
Variable display of SIDs on SID monitors (Sudden Ionospheric Disturbances)
Interests me how different stations show quite different traces. Here is mine (Lichfield Radio Observatory www.astronomy.me.uk) from 21/1/2026: It shows a very impressive SID at about 1pm. My goto website…
Strangely narrow SID on 26/1/2026 around midday
Strangely narrow SID on 26/1/2026 associated with C-class flare: From Lichfield Radio Observatory (my observatory in UK): Compare to SID Monitoring Station (https://sidstation.loudet.org/data-en.xhtml) – an excellent source of high quality…
What is format used in data files produced by Radio Sky Pipe II Software?
Radio-SkyPipe II (R-SP) uses a binary proprietary file format for its data files. Here’s a breakdown of the format, based on the Radio-Sky documentation: File Format (Radio-SkyPipe II) Interpretation /…
Two-core plastic-coated cable (e.g., speaker twin, figure-8) works fine for a VLF loop wound on a wooden cross
Two-core plastic-coated cable (e.g., speaker twin, figure-8) works fine for a VLF loop wound on a wooden cross. Here’s how to make it work well: So yes: two-core plastic cable…
Two-core plastic-coated cable (e.g., speaker twin, figure-8) works fine for a VLF loop wound on a wooden cross.
Short answer: yes—two-core plastic-coated cable (e.g., speaker twin, figure-8) works fine for a VLF loop wound on a wooden cross. Here’s how to make it work well: So yes: two-core…
