I would use a ton of Van Halen “Dead or Alive” in the imaging, however, the music doesn’t sound like it would fit so, nevermind.
As I understand it, each station is still limited to an 18mb data stream. Under ATSC 1.0, You could cleanly squeeze 1-2 HD channels out of it (not perfectly, but still get them if they were 720p) or, 1 HD and 2-3 SD’s with lower bit rates. Under ATSC 3.0, the codec and compression rate make it possible to get multiple, clean HD streams out of that same amount of data. I am not sure as to the exact amount of channels, but it would not surprise me if you started seeing “.8’s” as everyone rolls ATSC 3.0 out.
And thank you, Andy!
I’m not an engineer, just an old jock/programmer. What does this mean:
Frequency separation (kHz) Contour of proposed station (classes B, C and D) (mV/m) Contour of any other station (mV/m)
0.500 0.100 (Class A).
0.025 (All classes).
0.500 0.500(All classes).
0.250 (All classes).
5 5 (All classes).
5 (All classes).
30 25 25 (All classes).
**better THAN 1080
Uh Pat, you forget about 750? much better (except for Rome) thank 1080.
The subject came up on another thread on spacing and duplexing AM’s. Correct me if I am wrong, with FM’s full-power spacing is 4 channels. You can put a translator up as long as there are 2 channels of spacing on either side. (Do I have this part right?) We have stations on 89.1, 89.5, 89.9, etc. In Portland, there is a 1040 AM and in Eugene there is a 1050 AM. How close can 1030 be to either of those stations?
Please correct me if I am wrong: Isn’t one of the bigger/greater barriers for HD Broadcast the fact that it is not open-source? Other than the large, corporate broadcasters who have a stake in IBOC, how many others want to pay licensing fees each year to broadcast in HD/Digital? You don’t have that on the TV side. TV Stations aren’t paying some company a royalty payment for the right to broadcast in digital. If you did not have that initial, and to my understanding very expensive cost outlay, you would see more radio stations in digital/HD.
I hear Lars on 720 right now. Comes in a bit better than 660. So, 10k on the AM reaches from Eugene to Portland, even if it is a bit weak.
I can hear 660 faintly here in NE. Spanish, right? Am i listening to the right thing?May 12, 2021 at 10:15 am in reply to: Unknown rock song played on KXYQ (KRSK) in 1989-1990 #50564
Sounds like The Smiths
I can co-sign on KZEL coming in stronger. Dropped off parts in Salem and I heard it better.
I understand that with TV is it becoming more common to channel share like KWVT does. How common is it for AM’s or FM’s to share antennas these days? Is it always two or do you have clusters sharing the same antenna?
How close in frequency can you have two AM stations on the same stick?
