Make that 1470.065 or so for the computed fundamental, not 1470.65; fixed:
UNIDENTIFIED. 2940.129, March 1 at 0049, JBA carrier presumed second
harmonic from some LAm or NAm broadcaster on 1470.065 or so. Another
measurement March 1 at 0658 puts it on 2940.132. Others closer and/or
with better antenna gain and/or with less noise should be able to ID
this (Glenn Hauser, OK, DX LISTENING DIGEST)
