[Lowfer] [600MRG] True Confessions....

[Michael Sapp]

Eric: Thanks, I've been waiting to see what level you captured XSV with your 
phased beverages, given that my small lot rx antenna hears 8 to 10 dB down 
from your setup.....

Looks like I may have to wait for a WSPR15 run to hear XSV at his current 
ERP level.....73, Mike wa3tts
