[CQ-Contest] DSP Question

[Tom Osborne]

Hi Bob

If the DSP was in the IF, it would be a lot better than the  outboard units. 
They are usually installed between the radio and speaker, or headphones. 
While they work OK, you get a lot of problems with close by stations in the 
passband pumping the AVC.

The outboard DSP units do help though.  I used to run my FT-840 with an MFJ 
784B DSP and it made the difference between being able to contest and not 
being able to contest.  Now that I have a rig with REAL filters, it is much, 
much better.  73 and congrat's on the wallpaper.
