Re: LF: SAQ

LF,

A bit late be any way i want to share my reception of SAQ. The RX is my 
VLF grabber antenna and SpecLab V2.76b18. The signal is converted to 700 
Hz and filtered in a 200 Hz Filter with 100 Hz slope. The first time i 
played with the autonotch and denoiser filters. It may sound a bit 
strange and actually i like some band noise in the background but anyway 
it is an interesting thing, this denoiser. I tried this with CW signals 
of DF6NM on LF and got better results than using a even narrower filter.
If you want to listen to the results:

PS: Due to the presence of JXN and HWU it made no sense to pre-filter 
the band with a wide (about 4 kHz) filter and remove the sferics before 
passing the signal through the narrow filter...
