Jeep.

You're welcome.  Further, Marty reported that initially he thought that he 
remembered expecting to have to tap down or remove turns on L118 & L119.  
They also tried 11X using a lower channel number crystal but output was too 
low.

On the "administrative" side, I would suggest carrying the 2-digit channel 
number on up and calling it 91 rather than calling it 291.
