We also had a Ham a few doors down who would step on TV channels and would even bleed into the POTS twisted-pair wiring. We couldn't use the telephone when he was transmitting! The problem went away after I had some "words" with him.
Actually, the problem in that situation is entirely with the phone, not the transmitter. Phones should never be sensitive to radio signals. It is the manufacturers responsibility to fix that problem. Back in the days before you could buy your own phone, the phone company would put filters on the phone etc., to fix the problem, as it was entirely, 100% their responsibility to do so. As for the TV, while it may be possible that the transmitter may be transmitting where it's not supposed to, it's much more likely the receiver is receiving the signal when it's not supposed to. There are some simple checks that can be made to help determine the situation. Bear in mind there has been a lot of poorly made equipment that malfunctions in the presence of a strong radio signal. Again, it's the manufacturers problem. On the other hand, there used to be a problem with "CBers", who having no idea what they were doing, would crank out as much signal as they could, oblivious to the fact they were creating a very dirty signal that could interfere with other services. Then we have the situation where the interference cause that is entirely apart from the transmitter and receiver. For example, corroded metal can combine two or more clean signals and produce a signal on a frequency where it will cause interference. Improperly designed electronic gear can also cause this. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
