Sitting in the car, waiting, so I tuned for a few minutes to see if I could find anything interesting.
CHTO (tentative): 1690 kHz, 2052 UTC. Fair signal with long, deep fades. Very Middle Eastern-sounding music, some talk in a different language. Tuned in off and on for a few hours. Looked up 1690 and the closest stations to me are WPTX in Maryland with a newstalk format, CHTO in Toronto with 3 kW and an ethnic format, and WMLB from Georgia with "an eclectic radio format, playing classical music, folk music, jazz, show tunes, comedy bits, and some rock and roll." My guess is CHTO, but again, this is tentative.
TIS: 1670 kHz, 2053 UTC. TIS with computer voices announcing weather and windspeed for the Hagerstown, MD/Winchester, VA area. This one doesn't seem to be in the listings for TIS
