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

Subject: LF: Alpha benchmark
vlf
As a guide for those interested in VLF 9 Khz it would be useful if each station could use the Alpha station on 11905 Khz as a benchmark for quality of reception.
and let us all know hown efficient their RX system is.
In my case using an inv L 150 metres total length not resonated the report is minus 60 dB with a sig over noise of 25 dB. This seems an acceptable system for 9 Khz reception.
I can do better by resonating the antenna, or using my 136 antenna system re-resonated for 9 Khz
I get the impression that at some locations receiving is a problem, for various reasons including noise from being in the middle of a Urban environment.
Can we have some data.
