[Elecraft] K2 with an outboard DSP

Fri Nov 29 21:01:02 2002

I occasionally use a DSP-59+ and Motorola HSN4039A with my K2 with very good
results - keep in mind that in most instances, it is not necessary at all.   I like
the 59+ just a little better than the ClearSpeech DSP (which did a nice job as
well). I also use  a DSP-9 with my Kenwood TS-930S with good results. Picked up
both of the DSP's "used" for very fair prices. Just my limited experiences....
