[R-390] DSP IF

[Bob Camp]

Hi

The idea of putting a DSP IF processor on the IF output of an R390 
sounds like an interesting project. The nice thing about the 390 is 
that you can get at both the IF output *and* the AGC chain without 
modifying the radio at all. Given the high performance RF section and 
the mechanical filters the result should be very competitive.

Of course this gets into the general direction of witchcraft and the 
like ....

	Enjoy!
