Or we could pass another bailout bill of say 800bn to demo any hills blocking reception in city areas. That's a win win -- we create jobs and solve the atsc reception problem at the same time.
Maybe I should be running for office! Cheers Kon Sent from my iPhoneOn Mar 7, 2009, at 10:01 AM, "Allen Le Roy Limberg" <allimberg@xxxxxxxxxxxx > wrote:
Here in Suncoast Florida our reception of DTV with fancy rabbit ears and no wideband amplifier is substantially more satisfactory than NTSC was. This is so with both Zenith and Magnavox set-top converters. We live on a mountain top 22' above sea level in Port Charlotte, so our terrain is favorable.I suggest solving the Cliff effect by having him move to Southwest Florida while you can still buy a good house for $100K. We also have very little snow, though daytime temperatures can dip as low as the high 60's. Our summers are probably a little cooler than where he lives, too, but morerainy in the late afternoon.
