[Lowfer] JJY

I have a theory about what I am hearing on 40 kHz. I am positive JJY is 
in there late at night but the "pulses" or "ticks" at around 1.5 to 
maybe 2 PPS I think may be JJY mixing with my local 40 kHz QRM source 
which is present all the time. I think the two are so close in frequency 
that I am detecting their beat frequency as well their carriers.  Again 
just a theory.

I made some progress on getting my loop going last night. I think I have 
identified an intermitent BNC connector I use to couple my capacitance 
box to the main loop.

Will continue today.
