Steve,
I have not measured the roll-off of the the K2's bandpass and low pass
filters above 28.8 MHz, and I cannot help you at the moment because I do not
have my test equipment here..
My K2/100's receiver did have a couple of fairly strong birdies near the top
end of ten, which IIRC were due to some harmonic of the BFO being heard by
the desired response or a spurious response of the receiver e.g. BFO x 6 =
approx 29.479 MHz in my K2.
73,
Geoff
