[hpsdr] Diversity experience.

[Kjell Karlsen]

Hi all.

I have lately experienced how efficient the diversity is to eliminate  
local noise. One month I got some very high noise on 80 meter that I have  
located it to come from the ADSL line into my house. So far I have not  
been able to get rid of it but when using Diversity, I am able to suppress  
the noise >15 dB so that I can read stations that are totally unreadable.

But if I change the frequency up and down, even only 50 Hz, the noise  
reduction is lost. But if I activate CTUNE, the diversity noise reduction  
is kept even if I move to a totally different frequency. I have not seen  
this mentioned before but I may have missed it.

I am really impressed of the diversity. It is quite unbelievable how  
efficient is really is!

73, Kjell
