Hi Theo,

The fact that the other bands are clear, means that on 40 mts there may or may not be a bug, remember than HF is affected by atmospheric conditions, so it may not be your radio at fault just bad atmospherics on a particular band.

Solar activity plays an important role here to.

Anyway, if this is all confusing to you, may I suggest the following:

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.
Hope it may helps:

Bad reception


Sounds like you have an antenna problem. Find where the antenna plugs into the radio. Unplug it and find a nail or something the same diameter as the center pin wrap about 3-5 turns of a four foot piece of wire around the nail and plug the nail into the antenna input on the radio. If it clears up reception you have a bad or grounded antenna. Follow the antenna wire back to the windshield or fender etc. mounted antenna, sometimes there are other plug in points that get knocked loose.

Connection and Reception


I would suggest to try another phone. I am considering that the phone line is okay. It is possible that there is a fault in the power supply inside of the base station. I have seen the supply section in the base station go defective causing hum, and or complete failure of the phone.

If the power supply is at fault, the failure can be a voltage regulator, or some bad capacitors, or something along that line.

Bad reception


I see you've already read the "Troubleshooting" section of the manual! The only other things I can think of to check would be the actual connection between the radio (aka head unit) and the antenna. It's usually just a press-fit connection behind the radio, but if it's loose, corroded, or is touching some other metal, it could affect the reception.
There's also the small possibility something changed at the transmitter tower for the radio station. That happened in my area once, where they changed the direction in which most of the signal power was being broadcast. Westside reception got better, eastside reception got worse.

No reception sometimes


Either this is typical shortwave reception characteristics, or you intermittent antenna connection.

Intermittent reception problem


I think you have a loose connection inside the tuner. Sometimes this can be repaired by removing the tuner and soldering the connections. Sometimes the tuner will have to be replaced. The cable connector which sticks out the back of your set could be broken loose inside the tuner. This type of problem is very common. You never know when it's going to happen. IT will change with temperature. You need to have a technician check it for you. Stargazer
