Leigh, No firmware changes were made that should affect this. All I did was provide more robust rejection of ill-formatted commands that were coming from HRD and other programs when allowed to poll at too fast a rate. I heard from over a dozen users of various programs that this change completely cleared up the artifacts they had seen.
I suspect buffer overrun by multiple programs combined polling too quickly. 73, Wayne N6KR On Jan 29, 2012, at 5:44 PM, Leigh L.
