[600MRG] 630m noise

[J Mcvey]

 Maybe a notch filter might work, too?

 Is anyone here working on a way to increase their sig/noise ratio on 630m??

My WSPR receiver has been relatively deaf but I may be on the road to 
better sigs..

With the SDR receiver on 475 khz. and set for long FFT times I see a 
wandering, wide, noisy carrier coming down the water fall usually around 
474.8 or so...

And I see upper sides bands of the same 'carrier' going up through 476+...

I broke out the old Dallas Lankford home brew phaser and am using the 
80m windom as the noise antenna with the vertical loop as receive input...

I see instant increase in signal and strength gathering of WSPR sigs..

It is a work in progress so I'm looking for hints and kinks info..
