In the East Coast of USA, strong signals from R. Riyadh can be heard in many frequencies on high bands in daytime. In the following spectrum, the neighboring signal on 15225 kHz (right side) is another program of Radio Riyadh.

Receiver: Degen DE1103 Antenna: PA0RDT Mini-Whip (on the rooftop of car)
In the recording you can hear the station jingle of “Radio VBC” and “….Легендарное радио” (Lyegendarnoye radio = Legendary radio)…
This reception was likely by the sporadic E propagation. Some other stations from China were also heard on the FM band in Japan. Actually I don’t think PA0RDT Mini-Whip covers VHF, but still usable for this time.
