If you do a search between 497kHz and 500kHz you'll find that there are a
good number of unid NDBs in that area.

Hi Roman, LF,
I have also noticed the signal on 498.800 kHz.
I have looked back at 3 days grabber saves & the signal fades in at
about 1530utc & fades out at about 0700utc the following morning. At times
there appears to an accompanying parallel signal about 1 kHz higher which
looks like an NDB ID (see attachment), but nothing on my lists for
an NDB on that frequency.
I will set up another SpecLab to monitor that frequency & a few kHz
either side to watch for an ID type signal on the LF side as well as the HF
side of the carrier. I will report my findings to LF for anyne who may be
interested.
