Chinese broadcasts on 13 mhz

    Not to uncommon to hear stations that aren't listed on the Passport or WRTH books but its unusual for stations to just sort of pop up on bands they normally dont broadcasts on as example today I am hearing Chinese broadcasts on 13970 khz at 04:00 utc I was surprised as I heard similar at 14870 khz 2 or 3 days before and it was around 00:10 utc. Give a listen around the bands and see what you hear on the radio.And if you can post it to the varuius shortwave groups like ASWLC.
