    :rolleyes: Everything you need to know is also presented, IMO, in a simpler and more straightforward manner (assuming you know how to use a spreadsheet) in the two links I posted above.

    Comparing both lists with what my TiVo has as physical channels, the first 10 I checked have not moved.

    AFAIK, TiVos have never used PSIP data (they probably should, but they don't). From personal experience and other posts here, the only thing that a channel scan can accomplish is to identify an active channel that isn't in the guide data.

    If a channel isn't in the guide data it's useless anyway as far as TiVos are concerned. Fixing the data is the only real option.

    It was pointed out to me a while back that in Diagnostics, the item "Program Number" is the sub-channel. Not saying it matters, but it is displayed. Since it is also accurate with QAM channels, I'm not sure if PSIP is where it comes from.

    I already went through this back in January when several channels that sold their spectrum vacated their frequencies and became sub-channels of sister-stations. It took 10 days for Tivo to get most of the information right, but one station took at least a month (not a station I watch, so I wasn't paying that close attention). Here is my thread: Guide problems after channels change RF assignment but keep PSIP

    I noticed a few channels are moving to a higher frequency within their current UHF band. I thought the purpose of repacking was to move the stations to a lower UHF band or move to VHF to free the higher UHF frequencies for 5G.

    The auction took UHF channels 38 through 51, which were devoted to TV, and sold them off to cellular/wireless. (Channel 37 was and still is reserved for radio astronomy.) So there's all kinds of movement among the UHF and VHF frequencies up through channel 36 now. In some cases, yes, stations are moving upward within their given band, such as from UHF 14 to UHF 26. It's quite a puzzle to assign a frequency to all of the TV stations without there being any interference between them and other stations in nearby markets. That's why some stations that didn't participate in the auction are still having to shift to a different frequency within their current band.

    Not sure why more stations didn't participate in the auction since there was a chance that they would have to change frequencies anyway. Might as well get paid extra.

    I believe that the only voluntary options for high-power stations in the auction -- which would result in the station getting auction money -- were to either give up their frequency (via frequency-sharing with another station, or going completely off-air) OR to switch to a lower (less crowded) frequency band (e.g. from UHF to VHF high; from VHF high to VHF low).

    There wasn't a voluntary paid option to switch frequencies within the same band. However, I think the FCC does provide some money to stations that are forced (didn't volunteer) to switch to a different frequency in their current band, to help them cover the associated repack costs.

    Someone correct me if I'm wrong on any of those details.

    On the bright side, since the TV channel spectrum band will become narrower, this should theoretically make it possible to design better TV antennas that can focus better on that narrower band.

    Ironically, larger (but not noticeably) UHF antennas will be needed. Much of the UHF antennas on the market today were designed to be wide-band from 14-69, if not 14-83. Ideally you'd want to design your UHF antenna to perform like a star from 14-36, and be a dog north of 37 (to keep out cellular signals).

    Now we are nit-picking here, but the sweet spot for many UHF antennas is north of RF 30... Maybe it's time for ChannelMaster and friends to revisit their products... But I doubt they do, as there probably isn't much ROI...

    I have no doubt that someone will design a better TV antenna once the switchover is complete.

    So, when an OTA channel changes frequencies, and you rescan on the Tivo to get the new mapping, it adds the new mapping but seems to leave the old dead frequency mapping in place. Any way to simply remove the no longer valid leftovers from the legacy scan ? Is this too much to ask? I know you can uncheck it in channel list, but there really shouldn't be the box around to uncheck.

    Perhaps this is related to the new frequency mapping arriving at a different label for the channel. For example, since the frequency sell off in January we have KQEDDT2 and also KQED+. One mapping is current but it's not the one with the name KQED gives to the channel normally (KQED+) which is connected to the old dead frequency. Maybe if it were the exact same name, then Tivo itself would auto-delete the previous mapping.

    I guess this explains why I’ve been getting channel changes where the channel is removed and re-added, though they are happening on my cable Tivo so the channels are removed and re-added to the same channel. That’s been happening frequently the past few weeks, even though the channels in my area aren’t supposed to shift until August 2nd.

    RabbitEars.Info

    Since this includes 3 out of 4 major stations, I guess it’s a good thing they picked the middle of the summer to do it.

    What’s odd about that list is that the channels are swapping around. Only one was above 40. I guess this is to prevent conflicts with neighboring regions, but all the stations that are swapping frequencies are within a mile of each other.

    I've got channels mapped to multiple frequencies now and repacking won't start here for a long time. I have to uncheck the ones that don't work.

    I've got several duplicate channels that appear exactly the same in all details, yet one will work and the other won't. It is quite a trick to choose the right ones to uncheck.

    I just developed this issue this week. I did a channel rescan, a guided setup, and a reboot. What did you do? I use a Romeo OTA dvr.
