Yes Rog - recorded from headphone socket of AR7030 with
fairly wide
1.3kHz IF filter. I haven't a narrow IF filter in that RX, but
an
outboard 2 stage 100Hz active filter has been built recently. Didn't
need to use it last night on your signals as you can tell.
I have
screen grabs stored for each 5 minutes for the last several days
that I'm
going to analyze to to see how the path between us (and any of
the other
continuous beacons that I see) varies. You are always a nice
signal at night
but disappear quickly as daybreak approaches, with
nothing visible during
the day.
I don't want to wish the summer away, but after the equinox
500kHz will
get a lot more user
friendly!
Cheers,
John
