The 10 MHz WWV may be the worst place to check the performance of the K3 Sync-AM. I feel the 10 MHz WV transmitter has some apparent frequency modulation and audio distortion not present on any of the other frequencies (or on WWHV when I can hear it). On the other hand, I also detect the momentary "unlock" on the 15 MHz WWV transmissions but those unlocks are associated with audible fading. 73, ...
