When 3 of top 5 stations in Denver (KUSA/NBC, KMGH/ABC, KTVD/My) dropped their analog April 16th, by far the biggest problem is with converters and receivers that do not re-scan properly. A recent article shares the frustration of many viewers, myself among them. I too had to delete old channels before the converters would access the new channels, and in converters that do not allow channel-by-channel changes, you had to figure out how to completely re-set the receiver. The far bigger question is why the ABC & NBC affiliates did not retain their UHF assignments? They had excellent channels, 16 & 17, but chose to return to their old VHF assignments, 7 and 9, at a 7 to 10db power reduction. The other UHF channels are working great, even in challenged locations. But for viewers who needed only rabbit ears now need to go to outdoor antennas makes me question the wisdom of these stations. One chief engineer told me, "we can use our channel 20 signal for Mobile TV, we didn't need 2 UHF channels." Expect the big re-scan issue to be the June 12th bugaboo nationally.
