[600MRG] Best receiver settings

[Dave Riley]

Thanks for all the answers...

I use the SDR-IQ to see noise floor and signal ratio.. Around here we 
get plenty of -100 to -105 noise floor, YUK..

Adding the 300' loop on ground went a long way for sigs below 80m.. Home 
brew 2 channel amplitude/phase variable usually finds a dip in noise.. 
As Rudy pointed out, there sure are many noise sources and some real 
interesting coherent sigs as well..

That settles it nicely for now..� 73s de DaveR @ aa1a
