An update on the spot function problem I had with my K2: After a few more calibrations I found the spot problem to persist. I finally tried testing it with a different transceiver instead of the KX1, and the spot function is working properly. As it turns out the KX1 was improperly calibrated -- not the K2! I calibrated the KX1 and now everything is working well.
