NexStar, the media company that owned the San Diego market FOX affiliate (KSWB), recently purchased a second TV station in San Diego, KUSI. On January 16, 2024, KSWB and KUSI became the first two stations in San Diego to broadcast in ATSC 3.0 (NextGen TV). Since the FCC requires stations to continue to simulcast an ATSC 1.0 signal, switching to ATSC 3.0 requires a sharing arrangement. Since NexStar owned TWO TV channels in the market, it was easy for them. What isn't easy is the problem that popped up....
On January 13, 2024, ATSC 1.0 signal of KUSI (channel identifier 51and broadcasting on RF 18) was moved to the ATSC 1.0 KSWB (channel identifier 69) transmitter (RF 26) as a sub-channel on 69 (69.6, to be exact) but the channel identifier for KUSI remained 51.1. Thus, the ATSC 1.0 signals for both KSWB (FOX) and KUSI (Independent) were on the same transmitter.
On January 16, 2024, the ATSC 3.0 (NextGen TV) signals for both KUSI and KSWB were started up on the RF 18 transmitter (that formerly hosted just KUSI ATSC 1.0).
Of course, we had to rescan channels after those dates to find the correct RF locations for those stations. The image quality on the ATSC 1.0 signals took a hit, the bandwidth was lower and it was quite visible. I don't own an ATSC 3.0 tuner, I can't personally vouch for the signal over there.
Then, on the morning of January 23, we woke up to find that both KUSI and KSWB (ATSC 1.0 signals) were off the air. Gone! Attempting to rescan the channels resulted in NOTHING being found for 51 and 69.
It's been almost a week and the two ATSC 1.0 signals have not returned. None of my fellow over-the-air friends in San Diego can tune the channels either. Over on AVS Forum there is a guy in Rancho Bernardo who claims he is receiving the signals on ATSC 1.0. Ditto for a guy up in Moreno Valley (90 miles away). But I don't see how that is possible. A receptionist at KSWB confirmed to me that the ATSC 1.0 transmitter is off the air.
Supposedly, the transmitter is being repaired. But I'm getting rather impatient. We could not watch the Lions/49ers NFC Championship game yesterday because it was broadcast on FOX. Grrrr...
Regarding the guys in RB and Moreno Valley... Is it possible the transmitter has antennas for two different distances? One to broadcast to nearby households (say, under 20 miles) and one to reach farther? If so, perhaps the short range broadcast antenna is on the fritz?
At any rate, San Diego's first foray into NextGen TV has really SUCKED!
