WWV noted on all five frequencies: 2500, 5000, 10000, 15000, and 20000 kHz
CHU heard on 3330, 7850, 14670, as well as the second (6660) and third (9990) harmonics of 3330.
In the past I have also heard 13320 (4th harmonic of 3330) as well as a mixing product on 6820 (14670-7850) but neither is present ATM.
