Stan, I just looked at this video and your picture signal looks excellent! However, the signal interference or degradation you're talking about definitely looks like some sort of interference (such as electrical or power tool). There are some website instructing how to rule out interference on radio antenna reception. (ie. Go to your breaker box and switch off each circuit or turn-off each electrical appliance in your house to find the offending device.) One of my interfering devices was a vacuum kitchen Food Saver interfering with my AM radio reception. AM frequency is extremely sensitive, unlike FM (or TV). Beware of devices such as the Food Saver which are actually "on" 24/7 while plugged-in. Another thing to look for, is your antenna cable. I ran RG-6 inside of non-metallic conduit as I also have a metal roof and my low-voltage cables run close at times to my indoor 12/2 electrical wiring. Obviously, I'm being extra safe, but in < -40F temps, plastic wire insulators simply crack here. Plus, with conduit, I can just pull new cable whenever. Also, my telephone line ran next to my incoming electrical causing interference ... against code to run low-voltage along side electrical. Since I've separated the incoming telephone wire from running along side my incoming electrical cables, drop-outs have apparently significantly ceased. Yea, that signal looks excellent. Mike's the expert on this though. Some ideas to get you trouble shooting though. :-) -- Roger http://rogerx.freeshell.org _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
