An occasional one isn't a problem, but if you're getting a lot of them, it will affect your Rx performance quite a bit.
I think of an occasional 'S' as the same as an occasional "RFI hit" on the channel. But when the rate of them gets to the point where you're losing a significant amount of Rx data, it's a problem. -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
