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
Bernie,
If you already have an external DSP you can get nearly the same effect
with it as you can with the internal one. I have that setup here - K2
w/KAF2 and Timewave 59+ - and for comparison recently borrowed a
friends K2 which had the internal DSP. I could find no situation where

I agree with Bernie on all points and I actually have the same setup as him and
99% of the time I just use the crystal filters and the attenuators. I do use
the timewave from time to time on really strong signal. I find that using the
attenuator better at digging out weak signals out of
Dear Folks:
I have just finished building K2 #6922. It took me almost 20 months (I'm a
slow builder), but with the help of God and Gary Surrency (not necessarily
in that order), it fired right up and in just a couple of days, I've worked
8 states and three DX entities (Panama, Venezuela and
The noise limiter of the DSP dramatically cuts the QRN at my QTH. It does
make some CW signals less pure sounding, but its a good trade-off for me..
I almost never use the other filtering abilities of the DSP. I haven't yet
learned what advantage that offers over just narrowing down the crystal
