I also have the C Crane transmitter.  They sayy there's a pot in there 
somewhere that can be adjusted to increase the power a little.  Mine covers 
my property very well without such an adjust.  I have been thinking, though, 
about tuning a VHF amplifier I picked up, down into the FM broadcast band to 
see what it would do--besides get me into trouble, that is.
