I just got a new 2014 Itasca that has a Jenson tv in the bedroom. When I run a channel scan for the air antena, it comes up with RF CH and a number plus found and a number. Now question is what does the RF CH mean? Is it more channels and how do you access them?

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. RF channels 2 through 13 are considered VHF, and RF channels 14 through 51 are considered UHF. There is more to this, but this is the simple explanation. Doug

The RF channel is the actual or real channel that a transmitter sends out. Embedded within the TV signal is information such as time, program title, program information, and virtual channel. This embedded data is known as PSIP (Program and System Information Protocol). The channel number displayed on your TV will be the virtual channel number. During the digital transition period when TV stations broadcasted both analog and digital signals, the digital signal was on a different RF channel than the analog signal. For instance, in Minneapolis channel 11 broadcasted their digital signal on channel 35, but your TV would display channel 11.

Now question is what does the RF CH mean? Is it more channels and how do you access them?In days of old when broadcastes were bolt the FCC assigned some specific channels, 1 through 82 ultimately, for their use, Well nobody used 1 so not it is the Six Meter ham band. (thank you) and 70-82 went away cause they also were not popular. That left 68 channels.And you selected the channel with your tuner, Channel 2 was, 56 MHZ center if I recall (Chan 2) I have a list if you want the rest.But with the switch to DIGITAL, they are no longer called Channels, they are called Services, and ... the "Channel Number" on your screen no longer equates to frequency.For example (This is from Detroit) Channel 2-1 and 2-2 (Channel 2) now broadcast on what used to be channel 7's frequencyChannel 7 (-1-2-3) now use Channel 41.That said, some stations still use their original frequency (Channels 7 and 13 near me here in Upstate S.C. both use their original assigned frequencies) THE GOOD NEWS, is you do not (normally) need to know this stuff, Your television's control computer figures it out when you do a Scan, remembers it so when, for example I tune to chan 7-2 in Detroit, it tunes to channel 41 and away we go. (Or here in the Upstate it tunes to chan 7) Very confusing to humans, not so much for the computer. The FCC would like to get everyone off the VHF bands and for the most part has gotten everyone off VHF-Low band (2-6) though there are still a few holdouts.. VHF-Hi has proven a bit harder to vacate.You see. they have re-sold those frequencies to others.

NOw they are starting on Ham Radio Frequencies too. Everything is about greed and money.

Some brands of TV searches count this example (5.1, 5.2, 5.3, 5.4) as 4 channels found, some say 1 channel found. I had sets doing each of these ways.One thing to remember is that you might not find all stations located (rotate the channel+ button) by leaving the antenna aimed in the one direction. If a channel or two are missing, stay on the channel and slowly rotate the antenna slowly until the signal is picked up for that specific channel. Not all located signals come from the same transmitter.
