Why does my antenna signal seem to break up or disappear around the same time every night?
WJCT is transmitting at full power using a Solid State transmitter, therefore there is no loss of power due to tube aging. If there was a loss of power due to our transmission path, our equipment would show high VSWR and alarm. Channel 7 is very difficult to receive due to the RF characteristics of the ATSC transmission and any problems your system my be experiencing will be apparent with Channel 7 first. Any loose or corroded connections leading from the antenna will cause signal degradation and eventually you will not receive WJCT. Check and clean all connections and inspect cables for any damage. There is the possibility that your receiver is aging and is not as sensitive as it was when new.
When all else fails, try moving the antenna. Sometimes the atmosphere is to blame.
Why do I have no audio for WJCT7-1 but audio for both WJCT7-2 and WJCT7-3?
WJCT is currently switching over to a new Network Operations Center (NOC), and we are experiencing some technical difficulties. You can try re-scanning. Also check and see if your TV is set to receive Second Audio Program (SAP). Most TVs should revert to main channel audio when there isn’t any audio on the SAP channel.
I’m hearing the wrong audio or no audio at all.
WJCT transmits with four possible audio formats. There is Stereo audio, Surround Sound, Second Audio Program (SAP) and Descriptive Audio, and not all programs contain all four audio streams. If a TV is set to “decode” SAP then Stereo audio will not be heard. Likewise if Descriptive audio is selected then normal Stereo audio will not be heard. Make sure your TV audio is configured to decode the proper audio. Every TV is different so you may need to consult your operator’s manual.
How can I improve my radio reception?
WJCT FM/HD 89.9MHz transmits with an effective radiated power (ERP) of 98kW. Typical antenna for FM reception is the Dipole antenna.
Other antennas used for FM reception are the Curved, Turnstile, Yagi and Log Periodic. For more Information on which FM antenna is best for you, please use the following resources.
What if my transmission is intermittent?
DTV transmission can suffer from the “Cliff Effect,” where the signal is suddenly lost and the picture begins to tile or simply goes black or blue, depending on your TV. To improve, make sure that all connections are secure and free from corrosion. Weather seal all cable connectors if possible. Try not to kink the coax cable, and avoid using twin lead. Use black or UV-rated tie straps when securing cables. Power lines can not only interfere with reception, but can also kill. Be sure to exercise extreme caution when working near power lines.
How can I improve my TV reception?
You can improve reception by using a properly installed VHF antenna. Look for a VHF antenna that is “V” or “T” configured, commonly referred to as Yagi antenna. The antenna you purchase should be rated for the distance from your furthest transmission.
UHF antennas, usually circular in shape, are not suitable for VHF high band reception, despite manufacturers’ claims. Some VHF antennas are also not suitable for VHF high band reception. Rabbit ears or indoor antenna are poor receptors for today’s demanding digital transmission.
For best reception, your antenna should be externally mounted. Because all VHF transmissions are line-of-sight, your antenna should be elevated above any nearby structures. Try to avoid mounting your antenna near trees. Water adversely affects DTV reception, and trees are buckets of water. It is common for spring to bring on poor DTV reception, due to tree leaf growth.
Why is my TV reception poor?
WJCT DTV is one of the most difficult broadcast signals to receive. As VHF Channel 7, it is the lowest high band VHF transmission in the broadcast spectrum. (VHF Channels 2 through 6, which are low band, were removed from TV broadcast due to poor RF characteristics.) Thus, some customers might have difficulty receiving WJCT DTV, even though its signal transmits from the tower at 8675 Hogan Road at 174 MHz with an Effective Radiated Power (ERP) of 18kW.
