What have you been smoking?

P25 will be in play in the public safety arena for at least another 15 years.
And Tetra is having IPR issues with Motorola and banding issues with the FCC 
regarding use in the USA.

There is NO 6.25 requirement. Only an equivalence, just as there is a 12.5 
equivalence for the current narrowband Part90 mandate.
So, you could run 4 talk paths in a 25 kHz channel and meet the 6.25 
'requirement' which has yet to be promulgated.

I am of the opinion that if you want to play with this stuff in Part 97, go for 
it. That's one of the stated purposes for the Amateur Service. I, for one, will 
continue to operate my 'wideband' fm equipment for the foreseeable future, and 
if/when a manufacturer makes amateur equipment with these digital modes for no 
more than 20% above current pricing, I'd buy it. I just don't see that for a 
fair number of years. Commercial digital equipment is around 50% more to have 
digital capabilities.
