At first I thought it must be Taiwan Area Fishery Broadcasting Station, but the ads heard later, accompanied by some echo, strongly suggests China... I think CNR1 is on this freq, you could check 1377 or 4800 kHz to check for a match. BTW great antenna, congratulations! 😍

Nice observation Ron :) Is this the first time you are noticing on this frequency? Nice Evening buddy 73!
