[Lowfer] JJY

I listened around quite a bit last night, I did not hear JJY. I did not
hear anything around 185 kHz (or see it on a waterfall). There were a bunch
of stations on 475.7 kHz. I guess this is the 630 meter watering hole? One
identified as W8JI on CW. It would go off the air and another would show
up, weaker, on the same frequency. There may have been at least three
stations in there. I also saw a station on 472.3. I tuned there and heard
the CW but not enough to catch the ID.

I also heard nothing of the broadcast station on 153 kHz. There was a very
weak carrier on 153 but I didn't see or hear any audio.

I was comparing my e-probe and my 1 meter diameter loop with the LZ1AQ
preamp. The loop signals seemed a little weaker than those of the e-probe,
but I heard everything with the loop that I heard with the e-probe,
including WWVB on 60 kHz, which was quite strong.
