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
