What does RF CH mean?


What is the difference between a RF channel and a virtual channel? The RF channel is the channel that the TV station uses to broadcast its signal. Before the conversion to digital, TV stations were normally identified by their channel number, and most people knew that a particular network was on a specific TV channel. While analog broadcasting was being phased out and all TV stations were converting to digital broadcasting, it was necessary for the TV stations to continue to broadcast their analog signals on their original RF channels, and also broadcast their digital signals on a different RF channel. However, since the TV station used their broadcast channel as part of their identification, they wanted to keep using the same channel number. To allow this to happen, the new digital television broadcasting standards (ATSC) provided TV stations the ability to continue to use their original channel number and also tell the TV set to tune to the new RF broadcast channel when their virtual channel number was selected. The original channel number is called the virtual channel number, and it will be followed by a period and a second number (3.1, 7.1, etc.).
One of the benefits of converting to digital for the TV stations is that they now have the ability to transmit more than one program at the same time on the same RF channel. The number of additional channels they can broadcast is determined by the resolution of the program (SD vs. HD, text only, music only, etc.). The second number in their virtual channel number indicates that one of the additional programming sources from the same TV station is being viewed (10.2, 10.3, 10.4, etc.).
When selecting an antenna, it is important to understand the difference between the RF broadcast channel and the virtual channel. Antennas are designed to receive specific ranges of RF channels, and the antenna needs to be selected for the RF channel you wish to receive. TV stations broadcast in two broad frequency ranges, called VHF and UHF. RF channels 2 through 13 are considered VHF, and RF channels 14 through 51 are considered UHF. In order to pick up the channels, the antenna has to be designed for the correct frequency range. It is very common today to find that TV stations using virtual channels 2 through 13 are actually using RF broadcast channels in the UHF range. Although not as common, some TV stations using virtual channels 14 through 51 are actually transmitting in the VHF range. An antenna designed for only UHF channels will not work effectively for RF broadcast channels in the VHF range, and an antenna designed for only VHF channels will not work effectively for RF broadcast channels in the UHF range.

GE Model 20GT360 TV and digital antenna problem


Are you connected to a digtal converter or just a digital antenna? If only to an antenna then yes you will most likely pick up one or two low power UHF stations that are still able to broadcast in analog.

I have a 2004 S40, and when I tune to certain stations on the radio it'll play the station for a few seconds, then a search code will appear, and the radio will go silent for at least thirty seconds, it'll...


It will stop the search if you push the exit button, I also believe the dealer can do a software uprgrade to prevent it from happening again.

Digital channel numbers are different


The channels for a digital stations are really just "names". Thy will be the number for the old analog channel followed by a "-" and a number 1 through 4. The actually frequency can vary
from the old frequency. You can see this at;
http://www.tvfool.com/

To set up your tv, you will have to connect your signal source (Antenna or Cable) to the set.
Go into the menu and select the Signal source (Channel) to match what you connected.
Go into the menu for scan or auto program and SCAN in the channels in your area.
Now you can watch the stations on your set.

If the broadcast frequency of any station change, you can re-scan it in again. The "name" will not change so the change will be invisible to you.

Channel selection


What you need to do is take the remote, go into the menu, find channel scan and do a channel scan to find all the available stations available on this system. Make sure the TV set is in the cable mode and not antenna mode or you wont get any stations above channel 13.
