[BC] RF absorption by foliage

[Ed Trombley]

Dave:

That's a good guess.  I've seen carrier nulling on many arrays with tight 
nulls.  But this is different.  This happens with dead carrier.  When your 
in the area where this happens it makes no difference what station you tune 
in.  You can dial up any Detroit, Toledo, Monroe station and watch the 
meter bounce up and hold then bounce down and hold.  WJR is Non-directional 
and I seen it happen on their signal.  It will do it for hours and then it 
just quits and may not come back for hour or days.

This problem usually occurrs when the null is very deep.  As  modulation
