[600MRG] WG2XKA

[Rudy Severns]

I got four decodes for John last night between 0728 and 0930Z,  from just 
before midnight here until about 1:30 AM.  Been snowing here all night, cold 
and nasty with a nice thick base of ice.

I've finally tamed the noise monster here, at least a bit.  I put up a two 
element vertical array, 28' verticals spaced 200', with the DXengineering 
NCC-1 phaser.  It's not perfect but it works much better than the MFJ1026.

Before getting the rx array going I would have the prison bars drifting 
across the WSPR display, sometimes wiping out the signals.  No sign of the 
bars at all for the past few nights.  I still have broadband noise modulated 
with 60 Hz harmonics (up to 720 Hz) coming from the power lines but that's 
down to S3 which is much better.  I'm surprised I've improved the broadband 
noise since it's coming from the lines all around the property and not very 
susceptible to nulling but I'll take what I can get.  The TS590 has a very 
nice DSP filter and by moving the lower edge of the bandpass up to 500 Hz I 
can suppress that noise pretty well.   I find adjusting the filter bandpass 
while watching the waterfall display in ARGO to be really neat!  I'm going 
to play more with the DSP filters and see if I can improve your SNR's even 
more.  On Sunday night I began with the usual 80' single vertical for rx and 
then later in the evening adjusted the phaser and switched to the new array. 
There was a immediate 6-8 dB jump in your SNR's!

73 all, Rudy
