I spoke too soon! I think I can see it on a waterfall now, but using a
passive wire antenna. Whether the ALA1530 loop has a low enough noise
floor to use it to DF is a moot point. I'll keep an eye on things see
if I can get something to get a bearing on.

In the meantime I've set up SpecLab to save a grab every 5 minutes to
my public Dropbox folder, here:

The grabber covers 497.6 - 499.2 which shows the LF edge of the noise
at 498kHz. I might have to think about a Perseus now, to look at
wider areas. An SSB bandwidth suddenly looks so limited!

Cheers,
