SAQ Alexanderson day
SAQ came up this morning sending out message on their VLF frequency of 17.2kHz The signal was received quite clearly.
An 8kHz sampled copy of the audio signal from the 09:00 UTC (10am BST)transmission received indoors in Glastonbury
This was received inside the house using a similar rig to last time, using SAQrx to record the raw RF signal sampled at 96kHz, then passing this through Spectrum Lab for better selectivity and impulse noise handling.
