From the other site's uplink report:

So, there is at least some hope that Dish is working on updating the TSID to get the OTA guide data that is already uplinked mapped correctly, and maybe even adding some new OTA subchannel guide data. Also from the same uplink report:
New Uplinks / Mappings - Channels NOT Available
14186 KLKN LINCOLN, NE (ABC) added to 110° 27s29 (SC Nebraska) (OTA EPG Data)
No EPG - OTA Mapping (-01)
14186 KLKN LINCOLN, NE (ABC) added to 129° 5s20 (SC Nebraska) (OTA EPG Data)
No EPG - OTA Mapping (-01)
14186 KLKN LINCOLN, NE (ABC) added to 61.5° 32s13 (Nebraska/Kansas) (OTA EPG Data)
No EPG - OTA Mapping (-01)
14187 WLNE NEW BEDFORD, MA (ABC) added to 61.5° 27s28 (VT/NH/MA/CT/RI) (OTA EPG Data)
No EPG - OTA Mapping (-01)
So, it looks like Dish is actually uplinking OTA EPG's with no EPG data.
