Hi Stan,
Yes that is correct there are no meteor pings in that image but it was quite early in the night.
I just posted that screenshot to show that I do not have those strange lines I had before as posted in an earlier message in the ARGO help post. This was a major problem getting a good steady signal but with the help of a friend who also is an amateur astronomer and student we saw where the problem was. Samplings rate and latency settings in VB-Audio Virtual Cable.
Later in the night I started to see some meteor pings and then switched over to the right bar with ~ 40Hz Bandwidth and as soon as I power on the observatory or better said I power ON myself I will check the captured pings. I did capture images every 801 seconds after seeing that the screen fills up every 810 seconds.
Yes those 3 bars on the right as well as barely viisible on the left are periodic and come from another signal near my tuned 174 308 440. The meteor pings I have seen are all around 1060 Hz +- 50 Hz.
Thanks and regards Rainer
