Nice. I live about 75 miles south of WWV's Tx and I have never, ever copied it on 20 MHz. I don't know how much of that is due to my Rx setup vs. living within a skip zone, because I don't know the details of how they transmit on the frequency. I never think to check for 25 MHz because it's supposed to be on only sporadically. WWVH can be heard with regularity here in Denver, but it varies with time of day and frequency.
