Welcome to summer like static conditions. Programs that use 'visual' agc give little hint that an 
elevation of the noise floor has occurred ... signals just seem to vanish while the background 
'noise' looks like nothing has changed. Without 'visual' agc one can see that the level of the 
background noise has indeed increased and that the signal is no longer strong enough to remain above 
it.

Thanks for the report!

Jay
