I think those monitoring are using the latest version of Argo that
allows 60 and 90 second dots. I use different software / hardware than
can go arbitrarily narrow.
AGC is always bad news for any automatic monitioring. It kills any
record of the levels over time and is only there as a convenience for
QSO type operating, not for scientific experiment.
I meant to fix up the loop for listening at the weekend rather than
using the big E field antenna, as others seem to getting much better
copy from VA3LK than me, but got distracted by higher frequency projects
so will try over the next few days to get the 1.2m loop waterproofed and
set up.

I have switched off the AGC in Argo. Although this is very efficient,
it puts 'holes' in Morse elements when there is noise, instead of
displaying the noise itself. In fact, the only was I can tell
the noise
level has changed is to look at the apparent strength of the Loran
lines. This can be confusing. I will post some pictures to my
web site
to illustrate this.
Does anyone have any other tips on using this excellent program?
Also, I get tremendous QRM from the broadcast noises (Luxemburg
effect?) right at the top of the band during the late evening. Are we
really using the optimum frequency?
