I remember seeing other stations' IDs and weather bulletins from WPBN's VHF 7 transmitter near Harrieta. They lacked any direct coaxial cable link to NBC network programming, they picked NBC over the air from many other affiliates using over-the-air and microwave relay stations to get to NBC programming to Traverse City.CK-722 wrote: ↑Tue Dec 08, 2020 9:06 pmWPBN-TV 7 used to be a wall to wall signal in Mecosta County. WWTV 9 was somewhat stronger, and WZZM 13 a close third. WKZO/WWMT 3, WNEM 5, WJIM/WLNS 6 WOOD 8, and WJRT 12 were all receivable at higher elevations, and later WGTU 29 and WGVC/WGVU 35 were receivable. Even WJBK 2 and WWJ/WDIV 4 were receivable much of the time at higher elevations with a decent antenna. The WBRN tower and the then Rapid Cablevision had head antennas for all of these except 2 and 4 at one time, or another. Of course, WOOD 8 had an off air head end antenna link for NBC programming to WPBN near Stanwood, and WNEM 5 had a another head end antenna for NBC South of Barryton. For those who are too young to remember, WNEM 5 was NBC for decades before swapping with WEYI 25 CBS.
Common logos included WJMN-3, WTMJ-4, WFRV-5, WNEM-5 (NBC back then), and WOTV-8.
One night, their picture was overtaken by PBS's "Captioned ABC News" right at the 11:00 ID break.
Sporadic-E brought a signal that overpowered the OTA feed they had been using.
Logical conjecture would have that a PBS station took the channel by Sporadic-E skip, overpowering the NBC source WNEM had been using.
WUFT was in about the same azimuth as WNEM, and at about the "right" distance for an Es path on 77MHz at the typical sporadic-E single-hop distance.
