I hope the following fills in the blanks. The Term RF (Receive Frequency), for this context can be either UHF 14 - 69, or VHF 2 - 13. The repack has changed the UHF range to channels 14 - 36. They also deciding to assign channels VHF 3 - 6, in addition to VHF 7 - 13. Though, anything on VHF 3 - 6 will have interference problems, as was the case with analog TV.
KMGH, in their infinite wisdom, decided to remain on VHF 7 after the digital conversion. KZCO the TV Azteca affiliate was assigned UHF 17. KMG,H to boost its coverage area, acquired KZCO and added KMGH's signal. Hence, why fro along time KMGH was seen on 7.1 and 17.1, and TV Azteca on 72., 17.2. A couple years ago, KMGH added Laff, thatwent on 7.3 and 17.3,
When the repack occurred, KMGH relinquished UHF17, and instead decided to start up a new channel on UHF 26 in Windsor. But, because of the issues they still have with VHF 7, they decided to move to UHF30. UHF30 (formerly UHF28) was owned by another company, and KMGH had to share UHF30 wit it.
So, as you reported you are receiving 7.1 - 7.4 (duplicate), and 28.2 and 28.4. Which means the signal you are receiving is from UHF30. And, considering you are six miles north of Longmont, using a good antenna, you are really on the fringe. UHF30 is only 15Kw. It's full strength stops just south of Niwot, and just east of 95th Street.
As for UHF17, that became home to KPRJ (Trinity Broadcasting) which was on UHF38.
By this time, next year, the repack will be complete. That is when KDVR moved from UHF32 to UHF36, KCEC moved from UHF15 to UHF32, This so, KETD can move from UHF45 to UHF15. Also, there a some low power TV station moves, but these stat ions are so low in power, they would never reach longmont, let alone your location.
Once all these changes are made, UHF 14 - UHF36 will be occupied. VHF 3 - 13 will be occupied by Denver, Colorado Springs or Cheyenne stations.
So, just curious, what is broadcasting 28.2 and 28.4? I was once told UHF30 was airing on 28.1 - 28.5, in addition to airing 7.4 - 7.4,
