I've been experimenting with the DSP filters on my K2 and I have
found several combinations of DSP and crystal filtering that work
very well on CW (at least for me). However, I have run into a
strange phenomenon.
Here is how I reproduce it: I set my crystal filter at its widest
setting (1.8 KHz). The DSP filter is set for "low pass" with noise
reduction on. With this combination, I am able to find two identical
CW signals on either side of a center frequency. It operates just
like a direct-conversion receiver.
So here are a couple of questions for the group: First, has anyone
else seen this happen? If not, do you think it may be a construction
error on the DSP board? How about a screw-up in the filter alignment
or programming?
Thanks and 73,
John, WA6L
