@davehale...I've have had this issue w/4310 search "motorboat sound" "HD FM Radio" on the 4310 thread, there's quite a few of us. Sent my unit to Denon NJ replaced NIC card AND HD tuner, unfortunately unit STILL intermittently will do the "jackhammer" thing on HD FM Radio. I've never had it happen on my 4311, AFAIK you're the one of the first to report this on a A100/4311.
