The filters in my K2 have always been a little weird. Tuning around,
the signal would always peak at the wrong point and then drop when it's
at the correct sidetone frequency. I lived with it for a while. I
finally took some initiative and tried it out with spectrogram and
using the Elecraft noise generator. My findings were a bit suprising.
The filter shape has multiple peaks and is not uniform at all..
compared to a few others I have seen. I compared it to another friends
K2 and it was confirmed - my filter shape is funky.
What should I do? Do I need to buy new crystals? Is something out of
whack?
Thanks,
