And I dont see Freescale or others spending a lot of time and money on the 
obsolete MF/HF bands.

A pair of MRFE6VP61K25H does 1.8KW on 2m quite nicely with IMD3 better then
-40db.
On HF it´s a bit difficult to get them working as far I know.

##  To get good IMD3  out of that device... and  I mean, like -40db below
one tone, 9-46 db pep)
it has to be severely de-rated.   Run it in CB mode..and  IMD goes to hell.
Its maybe a 400-500w pep out device
at best.
