[Elecraft] Suggestions for K2 Options

[Bernie KF0QS]

Chip:

Thanks for your reply.  Since I can't afford the DSP right now, I'm going to
go with the audio filter.

Here is my thought on your question of the advantage of the DSP over the
crystal filter passband.  It is just my guess (and I could be off base) but
I suspect that the DSP gives you three advantages over the crystal filters. 
First, my guess is that you can make the passband edge sharper using the
DSP.  Secondly, whereas the crystal filters are somewhat fixed, you can
likely customize the passband more with a DSP.  I have an audio DSP (from
Timewave) and have quite a lot of options with that thing.  Thirdly, if
there is a way to link the K2 DSP to a computer, you can likely get software
updates from Elecraft?

The reason I'm not that interested in spending the money for the DSP is
that, despite these advantages, I'm not convinced that a DSP will result in
that much more of an advantage.  In other words, though technically I may be
able to accomplish more with a DSP, I'm not convinced that my ear and brain
will be able to hear and appreciate it.  And on those rare occasions when I
can hear and appreciate it, I have to then decide if those rare occasions
are worth the extra money.

I too would be interested to hear what others think.

Thanks again for your reply.
