[opendtv] Re: DTV Delay Bill

How easy is it to change frequencies?  I thought that transmitters were 
pretty much designed for one channel and weren't easily manipulated.  But 
it sounds like they can be changed in a day these days.  I imagine with 
new synthesized frequency generators, it is now programmable.  How do they 
work these days?  Is the RF processing and transmission path able to 
handle a wide spectrum?
