Great idea!
My case: my OTA PBS station NET on both 12.1 and 26.1 (KUON Lincoln and KYNE Omaha) is missing guide data. All the subchannel .2 and .3 data is there and correct. My dish is pointed at the EA.
All other OTA guide data is correct for the Omaha, Lincoln and SE Iowa PBS broadcast I receive.
that is weird as the chart shows OTA for both

One thing interesting is those are only mapped from the HD channel whereas the others are both the SD & HD
