Yes there are quite large but repeatable diurnal level variations, especially for the furthest Alpha transmitter. Around last March equinox, I recorded some plots, with the dashes from the three sour

Can we get a say 24 hour plot of Alphas/ signal to noise for your location Mal please? Id be very interested to see how quiet your location is. Cheers vlf As a guide for those interested in VLF 9 Khz
No problem but at present all antennas diverted back to 500 and 137 On the Alpha freqs and down to 9 Khz the difference between antenna OFF/ON is 30 dB atmospheric noise. Alpha signals always strong
Hi Mal I find the Alphas vary in strength throughout the day. Are you saying that at your location they're fairly stable and do not have diurnal variation ? I guess this may be due to the distances i

Well attached is a fairly non scientific graph of VLF stations over a 24 hour period from Alaska (GMT-9) - RSDN3 is included http://kl7uk.com/24hoursAlaska.jpg NPM, Hawaii my strongest signal paints
