You'd also need to go to a 100% duty cycle PA.

The K2 does a great job with AFSK, provided you don't have RF getting  
into the mic line, and you don't over-drive the audio input.

I don't know what you mean by a dual filter system. Do you mean  
filters at two different IFs? Like 8.83 MHz and 455 kHz? The K2 can't  
do that, since it isn't a dual or triple conversion receiver. It's  
single-conversion, which is arguably one of its strengths.
