That must be a record!
Not even close, a station in California has 17 channels.

The amount of channels a station can broadcast is all to do with how good the encoder is. This is an interesting read: https://www.broadcastingalliance.org...ywave-encoder/

Good reading. Now all will change with ATSC 3.0. Isn't technology wonderful?

OTA, CM4221HD, 3410 amp, 4 way split, HW-150 PVR.
FTA, Openbox S9, 33” dish, PLL LNBF. Stab 90HH.

Well theoretically speaking if ATSC 1.0 gave us 19.4 Mbps and ATSC 3.0 using OFDM modulation will give us 58 Mbps then that's 3 times the bit rate of the current 1.0

Now it gets even better as ATSC 3.0 will use the HVEC codec which uses only 20% to 30% of the bandwidth that Mpeg-2 is using. So lets put it that HVEC is 4 times more efficient then Mpeg-2.

So a station like WBXZ that currently has 12 SD channels using ATSC 1.0, now if they were to switch to 3.0 that would tipple the bit rate and quadruple the compression rate with the same quality as 1.0. So lets do the math 12x3x4=144 That would give them the capability of 144 SD channels. That just goes to show you the power of 3.0! Now I doubt anyone with 3.0 capabilities would do all SD channels... most likely a combination and possibly even a 4k channel in the mux. ATSC 3.0 is going to open up 4k to the broadcast market. There are so many other benefits from 3.0 one of which is the streams are IP based making 3.0 directly compatible with the internet. OFDM modulation eliminates problems with multi-paths, it actually makes use of multi-path signals to improve reception so well that you'll be able to receive 3.0 on mobile devices just fine, and that too opens up a whole new world of opportunities.

Well said Satellite97!

I've been very interested in seeing this new standard and all the attendant benefits it'll provide. I imagine most adopters will add low pay on demand services and other things just like the net.

ATSC 3.0 dongles and set top boxes are being produced, Geniatech have their a683 lined up for sale once they liquidate their current inventory of ATSC 1.0 dongles.

https://www.geniatech.com/product/a683/

LOWASIS are also showing of a STB with quad tuner that hasn't been priced yet, expect most of these to be sub $100 once they reach our shores.

ATSC 3.0 Gateway [LGA 5102] ? LowaSIS ? ????? ?? ?? ?????.

Things look very rosy for 4k high res multicasting out of the US, Canada will adopt this in 2030 or later once the US has got 8k 5g AI tv, they'll still broadcast only one station per RF but claim they are giving us a "better value and picture" using US 2nd hand obsolete equipment.


P.S. I was joking about the pox on your autologger Orbot, just wish I could snag some of these new transmitters you're getting.

IP based???
Does that mean you will need an internet connection?
Because if you do that defeats the purpose of free tv, plus they will know your location and possibly block US signals.

No you won't need an internet connection. 3.0 will use the Internet Protocol (IP) principal of communications derived from the Internet protocol suite for relaying datagrams across a network. The idea here was to make 3.0 directly compatible with devices that also use the internet... like mobile phones, etc. This also opens up another option for 3.0 and that is as an internet connection in its self. Some of that 58 mbps could also be used to stream some type of downloadable to mobile devices like movies or games. This could allow a station owner to make extra revenue on the side.

Here's a must watch video that you all will enjoy that was just posted of an antenna swap on a tall tower using a helicopter due to the repack https://youtu.be/XvykTt8BDPc
The new antenna is low VHF channel 4 and it's interesting to see it's designed with a circular pattern.. this is due to future ATSC 3.0 that the guy also talks about in the video.

9:15 am New WCMH RF14 VC4 Columbus Finally got it.

Stations from Columbus, Pittsburgh, Rochester and Utica have been booming into my location today. However, I seemed to be blocked from any signals to the west, so far today.

11:50 am New KONV Canton RF23 VC28
11:50 am New WVIZ now on RF35

Looks like WBBZ is going to carry this new diginet on 67-5. DABL:

https://variety.com/2019/tv/news/cbs...se-1203244886/

Blank for me right now but it logs in with call sign. I think the world needs less Martha Stewart, not more.

Only thing I’m getting from Pittsburgh is WPXI rf23, but the Erie stations are super strong wiping out all my regular Rochester stations that are on the same frequencies now.

I have one major complaint, WVIZ is now using up two frequencies on both RF34 and RF35. Such bs!
