This is typically caused by poor ground connections either at the cable input or inside the tuner itself. Check all external cable connections for good grounds. If those are good, then the tuner needs to be examined carefully for poor solder connections at the grounds.

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.

I think you are confusing the channel on the tv and the channel of the cable company that is not something that you can pick up with the scan tv, scan tv is good for picking up local channel meaning air channel that we get with a antenna only not the cable chanel

Dvdr3320v will this model record digital tv programs


This device has 2 composite AV, 1 S-Video, 1 Firewire, 1 RF video inputs. The RF input is a way for it to accept a signal from say a VCR's or Video Game's output on Ch 3 or 4.

Your device also can record via internal tuner.. The tuner can tune VHF:2-13, Cable:1-125 and UHF:14-69. Unfortunately, if you only have a UHF / VHF antenna on your house for TV (do not have cable TV, satellite TV, or the like) you're not going to be able to find anything due to the change from analog TV to digital TV. For this, you would need to purchase a digital TV converter box, and put the output of it into the the DVDR3320V.

I hope this helps and good luck. Please rate my reply. Thanks.

HDTV unable to get HD Channels w/ Antenna


The problem could be your antenna. Many people will buy small indoor tv antennas and wonder why they're not getting the signal that they want or the channels that they expect. Its not your fault. Digital signal is in two formats: UHF AND VHF. Some antennas only receive UHF. But many of the low band channels are VHF, so 1) you need an antenna that will receive those signals and 2) you need to know how and where to install that antenna and 3) you need to know if you need a signal amplifier depending on your coaxial cable length and number of connections. I recommend visiting dennys antenna service (no I don't work there and I have never purchased anything from that website. He just has an excellent informational article with a great deal of "how to" on his pages.). http://www.dennysantennaservice.com/2029710.html This should be of great help to you. Happy viewing =)

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.

Sk-32h240s unable to get all local channels thru ant. only what whould be the formally vhf channels, not uhf.


UHF needs a UHF antenna most all channel antennas do not work good on UHF,
Try the set at a friends house that does get those channels. UHF is harder to get and that is why a UHF only antenna is needed by most people. Lots of antennas are junk do a search and you will find the 8 bay C/M is rated the best by a large margin.
A good antenna amp at the antenna is also needed it should be a low noise one. A search will show the ones that work best.
The Gov. as much as lied to us and the TV Stations the type of digital they forced on us is the wrong one and millions of people even with a great antenna have lost TV.
