[RFI] 1Hz Noise

Thanks for all of the suggestions.  An electric blanket seems the most
likely source.  I live in a suburb.  I don't think there is an
electric fence anywhere near me.  None of my neighbors have babies or
toddlers so a baby monitor seems unlikely as well.

Unfortunately, the neighbor I suspect has the problematic device is
also the same neighbor that called Code Enforcement to complain about
my new tower before the antennas were even mounted.  I don't think
they will be very receptive to my attempts to eliminate interference.
Luckily, my neighbor's house is in a direction that I only beam when
working VK/ZL or AF/EU longpath.  I can't hear the noise when beaming
the usual EU, US, AF, or JA directions.
