am watching 189.000 +30, -30 Hz with Gram continuously while I am in the
shack here. There are two signals I am seeing on this part of the
spectrum, one carrier that goes on and off from time to time is on 189.008
kHz. There is a much weaker signal on 189.000 that in the daytime
is a faint trace line. There is another signal that is louder in
the evening on 189.000, I am assuming the two signals on 189.000 are from
different sources. I am looking for a LowFer beacon signal on 189.000,
so far I can not confirm I have seen it.</font></font> <font size=-1>There
was an M class flare at 11.59 utc, peaked at 12:14 utc, ended at 12:33
utc.</font> <font size=-1>At about 12:48 utc the screen presentation from
Gram suddenly went from typical noise spots to almost ZERO noise, the signal
level on 189.008 kHz stayed the same level and the trace signal on 189.000
kHz stayed the same level although it was certainly easier to see.
Without having the confidence of my observation I started poking around
for a bad RF connector in the system. The duration of the low noise
was for very nearly two minutes then the noise returned to normal levels.
By this point I had nearly torn the place apart looking for the bad connector
that I now feel does not exist. The low noise period had moved to
very nearly the edge of the screen when I realized that the 189.008 kHz
signal level had stayed the same throughout the event period, only the
noise had changed in level.</font> <font size=-1>The 15 minute difference
from the end of the M level solar event started me wondering if the lack
of noise and the M level event might be related.</font> <font size=-1>If
anyone else has an observation of a varying level of noise on LF during
this time period today I would be interested to hear about it.</font> <font size=-1>LarryVA3LK</font></blockquote>
