Jay, Walter,

QRSS30 would be okay - QRSS60 would be better. By shutting down at 0600Z

you are limiting the TA window. I'd suggest 0700 or even 0800Z if possible.
Do you have an accurate frequency readout of your TX?<

I would suggest QRSS30. As Jay suggests, the hour around your sunrise time
could be good. You should try to stay on until 0730 UTC, if possible.

I did look for the QRSS10 transmission last weekend, and saw nothing. But an
all-night recording might catch something.
