Gooday Paul:
I was really pleased to see the very clear capture this morning..... there were just very small bits and pieces all through the early hours - right on frequency but not worth ID.

I know that we get usable propagation all 12 months - when Bill Ashlock was starting his tests with the 50 ft square "Ashlock loop" I started copying him on a regular basis - and we found that I could copy this signal on 185 for every month of the year. Bill was using the familiar 2N3904/2N2907 combination amplifier and doing a lot of work with different conductors - from coax to copper tubing to wires in the trees, and I collected samples of the
signal practically every week. We are about 500 miles apart.

Picture: I used Photoshop - and cropped the big ARGO picture to just that line - and the frequency - as you see.
I am sure there are other photo programs that would allow you to do that part of the process.  Then I dropped the color - leaving it black and white to save a few more bits - then when I saved it I elected to save it as low quality - making it even smaller.

Maybe some of the other guys will pop in and suggest variations on this procedure..... but I think the trick is to keep the picture to about 35K-40K and then it is acceptable.

A very good and simple program for the PC is IRFANVIEW - and it is free - just open the ARGO capture in
this program - hold down the left button and drag the mouse over the portion of the picture you want to save -
and under EDIT select CROP. That's it - you can then save this new picture under another name - and then attach it to your mail.

Here is one I just did on the PC with IrfanView - and its only 8K in size.
I hope this helps - let me know if there are any questions.
