[Lowfer] WM & SIW early this morning

[Michael Sapp]

Garry, Mike & All:  Also seeing only WM and SJ this morning in the 185.3 
window.  WM peaked up from about 0830 to 0930, then faded and came back 
around 1030utc.

WM faded again around sunrise and has been above the noise since then.

On 630m only a single VE7BDQ capture of -27 at 0720, but 50 some WH2XND 
captures ranging from -8 at 0452 to -28 at 1206 with the 16 bit internal

soundcard in my old Vista era Acer netbook. (The 24 bit external Xonar sound 
card and new Acer would have dug a few dB deeper into the noise)....

I switched to my 300kHz LPF and single rx IF feed at 1446 UTC.  At the time 
of the switchover the WM signal went from -78 to -75 but I'm uncertain how 
much

of that was due to the equipment change or propagation.  Next capture frame 
may tell if the background gets noticeably darker.  Seems like the 300kHz 
filter has less

effect on background noise with the NW pointed EWE, even though 570 kHz in 
Youngstown OH is close to the top of the S-meter scale in that direction 
(many other AM stations weaker

levels tho, especially the 50KW 4mi away)....also less nearby commercial & 
industrial activity to the NW direction here.....
