Work wasn't ready for me Friday night, so I DX'ed MW on the truck stereo. Listening to that Hudson Valley TIS on 1710kHz, at 03:20UTC, I heard CW under the main TIS signal, but not for long. So, I didn't ID that. The TIS provided the carrier, and that CW beacon must have been a couple of kHz off FREQ. So, did I hear one of those Part #15 CW MW beacons? Possible, but it was very short. Anyone else hearing that?
