I am very impressed with the K2 RCVR and DSP. I didn't really expect
much DX on 40M but usually around 11:30 pm (0330 UTC) and around 7005
KHz lots of European stations from Russia, Bulgaria, Ukraine to
France, Sweden, Germany. But last night I heard 9J2BO, Brian, in
Zambia. No QSO but impressive nonetheless (to me anyway).
I have heard some report dissatisfaction with DSP in the K2. Here's
what I do. I use wide open bandwidth and no DSP until I find a weak
DX station. I tighten up the XFIL and then apply the DSP. (Frankly,
I don't usually use the AFIL much ... it seems a bit redundant, even
though the AF filtering is different than the XFIL.)
I find the DSP usually makes a very large difference in the noise
floor and the weak signal is much more discernible.
My two cents worth,
