Thanks for the feedback Gary !

Yes that was a bad blunder on my part thinking the camcorder would be 
able to pick up the CW. I can hear the CW in and out in the WAV file but 
that is about all. Also Bill is going to slow down the CW which will 
help a lot I think. One comment about the waterfall.....I have this Flex 
waterfall adjusted to show a flea-fart from a block away <g>. I tweaked 
it for several hours strictly for uW weak signals. I have it set on the 
hairy edge and the way it is set right now even a weak signal looks 
"impressive". For example the CW never rose more than about 5 dB above 
an averaged noise floor. But that 5 dB, like you said looks pretty 
substantial. It really comes in handy when I am running a sked with 
someone and we are both aligning our dishes......the slightest hint of 
his signal and I will see him.

Anyway TU for looking/listening. I will post better WAV's once the 
signal comes back up. Right now it is only visible 10% of the time as 
this rain/cold front just hit us. 73

This is why some people appear bright until you hear them speak.
