Title: 3420 (1710x2) W807 Harmonic 2351 UTC 12/1/2015
Post by: Kilokat7 on December 01, 2015, 2358 UTC

I just noticed this one on the waterfall while listening to TCS.  Peaking good at times and then down to just a carrier and back up again.  I'm hearing ads for Chicago businesses along Archer Avenue, weather prediction talk, etc. all indicating a harmonic from W807 "Geo Research Rock Radio" on 1710 kHz.  I've never heard this harmonic before and W807 (on 1710) is generally a weak signal here, so this is a bit of a surprise.  This might offer someone a chance to hear them better vs 1710.

I'm 20 miles NW of downtown Chicago and even in ssb mode I detect no carrier on either 1710 or 3420.

I have the faintest of carriers on 3420, but that is all.

After a good hour or so of monitoring 90 meters, it's mostly just a fuzzy carrier here with only occasional peaks to useful audio, peaking only 2-3 times within that hour to audio that could be understood.  I guess I just caught a lucky break.  BTW, the harmonic carrier seems centered at 3420.05

Great catch, kilokat!  I had some audio for a while, but mostly just carrier.
