YHD, nice one from HI... sometimes can't receive it here in Michigan.
It was one of those "brief encounters" - YHD and AA faded up enough for me to find them and when I checked back about 10 minutes or so later, they were buried in the noise. I just got lucky.
When I looked up the two stations in the databases, I was thinking that Dryden, Ontario (YHD) was in southeastern Ontario (closer to Toronto) but it was only after I looked on the map that I realized it's actually in western Ontario, about 150 km from Manitoba and north of Minnesota. That puts it close to the line of axis between Hawaii and Fargo (AA). Had I known at the time, I would have pulled out the NDB beacon map and done some concerted hunting for more signals from that approximate geographic area since I had clearly "struck a vein", so to speak. C'est la vie.
In any case, NDB is kind of interesting. I'll do some more NDB stuff over the coming years while I wait out the HF perturbations and low sunspots....
