I think that this is a splendid effort, however I do have a couple of
suggestions.
By posting an update every 15mins you are very soon going to be overwhelmed
with data.
I suggest that you make a plot that records the data over a six or eight
hour period and post daily in a similar manner to what Alan does. (Does
SpecLab allow this?). This would allow us all to compare the signal
strengths over a period and see if it can be correlated with any other data
and make possible predictions of good 73kHz TA conditions. They might not be
the same as for 136kHz.
A 15min near real time is very useful when deciding or running 73kHz tests
and perhaps they could be given in text as a data figure in dBs (that relate
to your chart), which could go to your site or the LF reflector as an
e-mail.
