In addition, of course, even if the signal were detected, it would be very brief indeed so it would be most unlikely to encounter a sweep that moves, in data communication terms, at a glacial pace. We are to note, too, that even if something were to be seen, then it would just look like a tiny flicker in amongst the rest of the "grass". > Again, apologies if all that has been considered. > John > at radio station VE7AOV. +++++
