VLF Radio Detection of SIDs (Very low Frequency detection of Sudden Ionospheric Disturbances)
Admin
How do I set up my SuperSID VLF detector software so that data from the Stanford SuperSID device is uploaded to the Stanford SuperSID data server?
To get your SuperSID detector automatically uploading data to the Stanford servers, you only need to enable and verify a few configuration settings. The functionality is already built into the…
To get plots uploading to vlf.astronomy.me.uk
Need to run upload-v3.py on LRO-SIDS5 (134cm aerial with direct soundcard input).

Sketch a practical 20 kHz tuning arrangement (variometer vs switched L/C vs active front-end) tailored to radio astronomy
At 20 kHz you’re really designing a resonant system, not just adding a tuner box. For your kind of radio astronomy / interferometry work, the most practical approach is a…

How far can VLF signals be detected under Polar ice caps?
VLF (Very Low Frequency, 3–30 kHz) behaves quite differently from higher-frequency radio because the wavelength is enormous (10–100 km). Under polar ice caps, two main propagation situations exist: These give…

Does anyone sell off the shelf antenna tuners that cover 20khz for VLF SID Monitoring?
Short answer: yes—but not in the way you’re probably expecting. 🚫 Off-the-shelf ham tuners: no All the usual amateur ATUs—like only cover roughly 1.8–30 MHz (HF). Even the “wideband” ones…
