17.2kHz Christmas Eve transmisison from SAQ, Grimeton, Sweden. There is a short break for receiver equipment testing at the beginning. SDRPlay RSP1a SDR receiver, 38m coax loop, WellGood loop amplifier circuit.

A small part of a once mighty inductor used at the 'Carnarvon' Marconi VLF site experiences high voltage, if not high current, 100 years after it (the inductor) was built.

Transmission at 17.2kHz to celebrate 100 years to the day since the very same Alexanderson alternator transmitter made sent its first message. Captured from Anglesey, north Wales on an 18m amplified loop antenna and SDRplay RSP1a receiver.

A Morse 'CQ' (invitation to respond) call being made via auroral propagation at 50MHz during a major and prolonged G4 geomagnetic storm.

An example of 6m/50MHz auroral propagation. Everyone is pointing broadly north, bouncing their signals off the aurora to make contact.

Ignore the poor sound. This was just an initial test to align the camera.

VLF transmission, Alexanderson Day 2024 (30/06) from SAQ, Varberg, Sweden. Received in north Wales, amplified 17m coax vertical loop, Wellgood amplifier boards. Short no-signal periods are during switchovers to 50m-long terminated Beverege (no detection) and PA0RDT mini-whip (no detection). A standard 3m-long amplified loop received only very weakly, but definitely.

When you forget you're not in Germany!

Auroral SSB heard from a non-ideal home location with a sloping 30m delta loop at 16:04UT May 10, under severe geomagnetic conditions.
