Possible that the TUNER has failed as the UHF band is not working. so it will be important to check the switched voltage onthe UHF pin of the TUNER to confirm that power is received .
If so the tuner must be changed.

Can't get my 21 1 ir/uhf pro remote to work with dish network dvr 625


If you are attempting to program it to tv-2 on a 625 receiver it has to be set to a odd number for example number 7 instead of 2 or 6.
The reason for this is that the 625 receiver only supports band A frequencies for UHF and on a 21.x remote odd numbers are A band and even numbers are B band.

How do I know if my Motorola CP185 is UHF or VHF without taking it to a dealer for programming?


Hi christo,

Yes the serial No. usually indicates the frequency band the radio works on, but not always, because a lot of radios nowadays can operate on both VHF & UHF, so not being familiar with your model, I can't give you a definitive answer.

I do have the feeling, for what it's worth, that it is in fact a UHF band radio, but don't take that as gospel.

Anyone else reading this post is most welcome to assist in helping a friend out, we would much appreciate your input, thanks.

Hang in there my friend, there will be an answer soon.

Cheers, Peter

Why can't i listen to aircraft pilots & tower on my Uniden bearcat BC60XLT-1? Our airband frequency here is 108-137 mhz.


Your scanner does not receive frequencies between 54 and 137 MHz, and there's nothing you can do to enable reception in that block. Your only option is to purchase a scanner with air band coverage. Here are the reception ranges of the BC-60XLT-1:

29.0-29.7 MHz 10 Meter Amateur Band
29.7-50 MHz VHF Low Band
50-54 MHz 6 Meter Amateur Band
137-144 MHz Military Land Mobile
144-148 MHz 2 Meter Amateur Band
148-174 MHz VHF High Band
Above bands in 5 kHz steps
406-420 MHz Federal Government
420-450 MHz 70 cm Amateur Band
450-470 MHz UHF Standard Band
470-512 MHz UHF "T" Band
Above bands in 12.5 kHz steps

Need the manual for your scanner? You can download and print it, at no cost, here:

Is my REGZA 42" 42HL167


This REGZA 42" 42HL167 has ATSC digital tuner built-in. when you set the TV to scan for channels, you must set the source to AIR, not CABLE. Since the Digital TV signals use the Old UHF band for transmission, your amplifier is made for this band? Try it without th amp first.

Please leave rating if it helps

Local ABC and PBS stations do not come in. All others local stat


Check to make sure your DTV antenna is an "all band" antenna with reception in both the UHF and VHF bands. It sounds like you may be in Philadelphia area. In Philadelphia, all the DTV stations are in the UHF band except Ch 6 and Ch12, which are in the VHF band. Some of the DTV antennas are UHF only. You can tell if yours can receive VHF if it has the "rabbit ears" long wip antennas. If so make sure the whips are extended fully and turn the antenna to try to get a good signal.

Visit the 6ABC and WHYY websites for up to the minute information about the issues with reception issues.

I get no stations on my tv


Use an Antenna that Provides Good Reception of All Channels
  • Most existing antennas used by consumers will provide good reception of DTV signals. (Before making any changes, try your existing antenna first to see of it allows you to receive all the stations you normally watch.)
  • For watching DTV signals, you will need an antenna that provides good reception of both VHF signals (channels 2-13) and UHF signals (channels 14-51) to reliably receive all of the digital signals broadcast in your area.
  • Many antennas are designed only for reception of either VHF or UHF signals (but not both). For example, the commonly used “rabbit ears” indoor antenna is only suitable for receiving VHF signals. To receive UHF signals, an indoor antenna should also include a wire loop or other feature for reception in that band.
  • The reception capabilities of TV antennas also vary considerably, so be sure to talk to retail consultants and look at information on the packaging and/or the Internet to make sure that any new antenna you may choose provides good reception of both VHF and UHF channels. In addition, if you use an indoor antenna and receive signals on VHF channels, you may need to use an antenna with amplification.
  • Many antennas currently being sold as “HDTV Antennas,” perform best at receiving UHF signals; some of these models state that they provide reception of signals on channels 7-13 but actually perform less well receiving those channels. If you obtain one of these antennas, be sure it provides good reception of all the VHF channels as well as the UHF channels.
  • To check for the DTV signals that are available at your location, use the DTV Reception Maps available at www.fcc.gov/mb/engineering/maps.
Check Your Connections
  • Check that your digital-to-analog converter box or digital television is connected properly. Make sure your antenna is connected to the antenna input of your digital-to-analog converter box or digital television. If using a digital-to-analog converter box, also ensure that the antenna output of your converter box is connected to the antenna input of your analog TV. Refer to the owner’s manuals of your components if you are unsure of the proper connections.
  • Ensure that your components are plugged in and have their power turned on.
  • If you have a digital-to-analog converter box, tune your analog TV to channel 3. You should see a set-up menu or picture displayed on your TV screen. If you do not see a set-up menu or picture, tune your TV to channel 4. If you still do not see a set-up menu or picture, recheck your connections.
Perform a Channel Scan
  • Digital-to-analog converter boxes and digital televisions have a button, usually on the remote control, that is labeled “set-up” or “menu” or some similar term. Press that button to access the set-up menu. Using the directional arrow buttons on your remote, scroll to the option that allows you to perform a “channel scan.” The channel scan will automatically search for digital broadcast channels that are available in your area. Consult the owner’s manual of your digital-to-analog converter box or digital television for detailed instructions on how to perform a channel scan for your device.
  • Once the channel scan is complete, you will be able to tune to the digital channels received by your antenna. You should perform a channel scan periodically to check whether additional digital channels have become available.
Adjust Your Antenna
  • Small adjustments to your antenna can make a big difference in the number of digital channels you can receive. If you have an indoor antenna, try elevating it and moving it closer to an exterior wall of your home. After adjusting your antenna, perform another channel scan to see if your reception is improved.
  • While adjusting your antenna, it may be helpful to access the “signal strength meter” on your digital-to-analog converter box or digital television to determine whether your adjustments are improving the signals’ strength. The signal strength meter is usually accessed through the menu feature on your remote control. Refer to the owner’s manual of your device for detailed instructions on how to access its signal strength meter. Remember to do another channel scan after you have adjusted your antenna.
  • Television stations broadcasting in digital use both the VHF band (channels 2-13) and UHF band (channels 14-51). Many indoor antennas use “rabbit ears” for the VHF band and a “loop” or “bow-tie” antenna for the UHF band. Make sure you are using an antenna that covers both the VHF and UHF bands and have connected it properly.
If You are Still Having Difficulty:
  • Until June 12, 2009, some stations will be operating at reduced power levels. If you are not receiving certain digital TV stations, this does not necessarily mean there is a problem with your antenna or digital-to-analog converter box or digital television. Check with the TV station to find out whether they are planning changes that will improve reception.
  • When an analog TV signal is weak or receives interference, static, snow, and distortion will often appear on the screen. Digital broadcasting will provide a clear picture; however, if the signal falls below a certain minimum strength, the picture can disappear. This “cliff effect” means that if you watch analog TV stations that have static and distortion, you may have to adjust or upgrade your antenna system.
  • Simple indoor antennas provide minimal performance that may not be suitable for your location. If you are unable to obtain satisfactory DTV reception with your current indoor antenna, you may wish to obtain an indoor antenna that includes features for better reception of UHF signals, as well as VHF, and/or an amplifier to boost the received signal (often referred to as an active indoor antenna).
  • Generally, an outdoor antenna will get better reception than an indoor antenna. However, the performance of outdoor antennas can degrade over time due to exposure to the weather. If you are having problems, check for loose or corroded wiring, broken antenna elements and that the antenna is pointed in the right direction.
  • Try to keep the length of wire between your antenna and digital-to-analog converter box or digital television as short as possible for best reception.
  • “Splitters” that are used to connect a single antenna to multiple digital-to-analog converter boxes or digital televisions reduce the amount of signal available to each device. If you are having problems, check whether reception is improved without the splitter. In some cases an “active” splitter that includes an amplifier can solve the problem.
  • If you are near a station’s broadcast tower, reception of that station, as well as other stations, can be impeded by strong signal “overload.” Consider using an “attenuator” or removing amplifiers to improve your reception.
  • If you decide to replace or upgrade your indoor or outdoor antenna, many types are available from electronics retail stores at a variety of prices. Websites such as www.antennaweb.org provide information on the locations of broadcast towers and the types of outdoor antennas appropriate for the stations you wish to receive. If you need assistance with upgrading your antenna system, check with a local antenna retailer or antenna installer.
  • To check for the DTV signals that are available at your location, use the DTV Reception Maps available at www.fcc.gov/mb/engineering/maps.

Would you confer with me on this couple in Australia


If they are looking for analog ABC, it is low band VHF, ch2 to be exact,where the rest are high band VHF, and needs a decent multiband antenna to get it in alot of areas, well in Brisbane at least. We have Mount Coot-tha that has a good propagation to most metro areas approx 40km radius, although it starts to get a bit noisy on the ABC due to lowband interference issues. .
There are many areas of AU that use UHF for TV also. Not enough hills in many parts of the east coast to get the coverage, so there can often be UHF translators that you need to tune onto. I suspect the ABC problem does relate to them not using an antenna that is suited to VHF, saying this of course if they get the other channels (7,9, and 10) ok.

Go here for a more specific channel/frequency guide to determine if it is the problem by location. ABC is on different channels almost depending on what suburb you are in for some areas. If the DVR can do digital, then they should go that way as it is now UHF ch21. It may be that they are trying to get analog signals, that will be turned of in the near future... so tuning the system in for UHF propagated digital is the way to go.

Back in the day when I used to do antenna I recommended the Hills PF11 antenna, multiband 11 element yagi with low/high band VHF/UHF, or a PF17 (17 element) with mast head amp if they are in a marginalised signal area. But a UHF array is still the best way to go if they can process a digital signal. Hope that helps :)
