The third harmonic of the BFO appears around 14.4 MHz, if I'm not mistaken. I did notice an increase in the level of this spurious output on 20 meters when the cable was inserted. I didn't measure it or anything -- but it was louder.
Someone with appropriate test equipment might be persuaded to measure it, but of course it might vary from K2 to K2.
