I think it was about 2009 that the US went to digital television. Recently we purchased a new tv for the motorhome that is set up to receive digital
over the air tv programming. Is Baja still broadcasting in analog? Thanks RonCortezBlue - 6-21-2011 at 09:23 PM
From what I have heard, they are working on converting over, but I am sure that it will take a while.
So ATSC is replacing NTSC.
ATSC uses the UHF band.
However, if you need to get NTSC, you should be able to buy an NTSC tuner that will allow you to watch on your ATSC video in.gnukid - 6-21-2011 at 10:05 PM

ATSC uses both VHF (channel 8 and 10 in San Diego for example) and UHF bands. Before the actual change over the VHF stations used a UHF channel but
were still called by their VHF channel for branding. In digital you can map the actual channel to be any virtual channel you want. Which is one of the
dumbest things the FCC ever did to the off air viewers. All the HD sets I've seen and used are capable of both analog NTSC and Digital ATSC reception.
Change it in the menu.

New TV - No Problema

As TW stated.
Newer TVs are capable of receiving BOTH analog and digital.
The ONLY time the issue comes up is when you have an OLDER TV (analog only) and wish to receive Digital signals. That is what the Converters (which
I've stockpiled "Free" from the Feds) are for.CortezBlue - 6-22-2011 at 11:25 AM

Phoenix is the same, we have channels in the 2-13 range, but make no mistake, ATSC is 100% UHF.
What I really get a kick out of if is you went to Radio Shack and told them you want an HDTV antenna they would talk you into taking your old antenna
down and put a "HDTV" up in its place. When in reality everyone already had it. The true advantage is that it is a smaller antenna and it is easier
to pickup UHF signals further away from the source.TMW - 6-22-2011 at 12:47 PM

That is not correct. As I said they are on both VHF and UHF. KFMB is ch 8 and KGTV is ch 10 in San Diego. KERO is ch 10 in Bakersfield. The ATSC
channels are in the FCC core of ch 2-52. Many stations opted to not use the low VHF band (2-6) due to the noise level. The High VHF stations mostly
went back to the original channel they were on in analog. I know what I speak of, I am the retired chief engineer of KERO in Bakersfield and the
sister station to KGTV in San Diego and KMGH in Denver, all McGraw-Hill Broadcasting stations. Our Indianapolis station decided to remain on ch 25 due
to the noise factor on it's original ch 6. They ID themselves as ch 6 but are actually on ch 25.
In Bakersfield we opted to stay on channel 10 (our DTV assignment) instead of going back to ch 23 due to transmitter power savings. San Diego opted to
switch from their DTV assigment on ch 25 back to ch 10 at the switch. So did KMGH in Denver back to ch 7. I would have to look up LA but I do know
that 7, 9, 11 and 13 went with their analog channel number. The UHF channel number used by the statons was only until the switch over. Yes they bought
two transmitter, a UHF for use until the switch-over and a VHF when the switch was made. UHF transmitters consume about 3-4 times the power a VHF
transmitter consumes.
Because of the actual channel number used after the switch-over there is confusuion by the consumer as to what antenna will work. A UHF 4 bay bowtie
(looks like 4 sets of cat whiskers stacked vertically) will usually work with the high VHF channels. The UHF antennas that look like a sideways V will
not unless you are really lucky. This was a nightmare trying to explain this all to the viewer who bought a UHF antenna and could not get KERO DTV on
ch 10. Because we were a UHF analog on ch 23 they thought it should still work. The station still IDs itself as ch 23 but it is not ch 23 it is on
physical ch 10.
