I cannot set up my tv, after it had cable. when i try the setup program the tv will not accept any channels and sap appears on the screen. i want go back to uhf/vhf, can somebody help me.


If you are in the US, there is no logical reason to go back to UHF/VHF as there are no broadcasting stations using the analog frequencies anymore. Those old tuners will not decode anything that is coming over the airwaves. Thus their channel scans will not detect ant channels, making you think there is something wrong. You would need one of the digital converter boxes sold during the transition period and then you will only get your local channels, much as you would have before.

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.

What do I need that I can get local TV off air?


You need a suitable VHF/UHF antenna. Then you simply "Tune" VHF/UHF frequencies on the TV and it should find channels and automatically "Lock" onto and store them.

Since the digital switchover, I have lost channels, despite re running the setup and tuning. Any suggestions as to why this is happening?


I have a similar issue. When the digital switch happened here some of the local TV stations changed frequencies from UHF to VHF. I do not have a VHF antenna so I am unable to receive these channels. I do have a great UHF antenna, but it will not receive VHF. The fix is of course is a new UHF/VHF antenna. I am 50 miles away from the TV transmitters.

This may or may not be your problem. I hope this is helpful to you.

Tuner will not pick up cable box on channel 3, front and rear AV


In order for the TV to work with the cable box by using a piece of coax and tuning the TV to channel 3, you must make sure the TV is in "Cable" mode on the tuner and not "AIR or Antenna" the frequency maps are different between these types of service and channel 3 cable will not be the same as channel 3 on Air or UHF/VHF.

Often there is an auto program feature on TV's that will "scan" for all available channels, and this should select the proper input type.

Hope this helps!

No uhf with antannae


UHF channels are basically "line of sight" type signals. You need to be pretty near those UHF stations.
You need a Uhf or combination Uhf/ Vhf antenna to receive them - - Usually an out-door type.
Your TV needs to be set in the "antenna" mode to tune beyond channel 13 "air type" channels. Channel 14 is the first UHF channel if you're in the antenna mode. If you're in the "Cable" mode then channel 14 is a cable channel which is operating at a different frequency from UHF.
I hope this will help you!

No UHF channels


Sorry, looking up the Phillips PTV100, it does not support over the air broadcasting. Supports, cable and satellite reception.

The reason you are picking up The VHF channels (2-13) is they match cable channel frequencies up to this point. The UHF frequencies are not the same as the cable frequencies, even though the channel numbers seem the same.

Some other models or brands of TIVO may have this ability.

What's the channel frequencies for a common 22 channel motorola 2 way vhf radio?


Not sure what you want.....VHF band ius approximatly 130mhz to 175 mhz..... in that VHF band there is a commercial VHF band aprox. 155 mhz to 175...... the amateur radio vhf band is aprox. 135 to 150mhz.

 

With amateur radio, any freq in that range can be used...... with commercial radio the FCC cangive a company any freq. in that range also.

 

If you are looking for FRS/GMRS frequencies they are UHF freqs not VHF.

So I'm not sure exactly what you want......sounds like you might want to program in FRS freqs into an Icom amateur radio. If thats  the case you will need an Icom that will do UHF freqs.
