OK.  I guess it doesn't matter if it's a TX convtr or a transverter for our
purposes.  But I don't see why none of the companies thought of doing things
the way I suggested.  It makes so much more sense and it allows one to
easily switch between U band and L band.  Having a 435 MHz IF really isn't
any more difficult or expensive than a 2m IF.

It looks like the converter manufacturers are stuck in the old 2m IF
philosophy.  

But I thought for sure that 435 MHz IFs are used.  I know I have a friend
who's 1296 xverter operates on a 432 MHz IF.
