[Lowfer] WM in EN90xn

Mike & All: I did get a partial capture of WM this morning.  No luck 
overnight as the storm down in the gulf near FL & AL
was generating too much QRN.  I used my NW EWE antenna to limit the noise 
for the overnight session, but that reduces the antenna gain in your 
direction.  This morning I did a 180 degree phase combiner arrangement on 
the NW and SW EWEs, which gives me a west 270 degree peak. The QRSS lines 
from what apparently is WM came through.... Presently still seeing what 
appears to be light WM traces...

So you have my ragged-edge capture with the gain cranked up to 53/53 and 
visual AGC "on" in ARGO and the AGC "off" and NB "on" with my FT-817 and 
TXCO-9 as the receiver IF...

The sound card was the Syba USB dongle set at 24 bits and 44.1K sampling 
rate.

73, Mike wa3tts
