Hi all,

I just had a odd thing happen. I was on my landline talking when my handy (cell phone) rung. When I answered the handy my landline went to hell. Nothing but buzz and popps. I walked away about 2 meters and my landline was ok. Is this normal?

No it sounds like the radio transmission from the cell phone is interfering with the landline or phone. There are laws to stop that!

Cell phones put out the authorized signals, near or in the microwave spectrum, depending on band in use. Audio devices, such as telephones are not supposed to be sensitive to radio frequency energy, such as that produced by cell phones. Proper filtering and/or shielding in the phone will reduce or eliminate the problem, but is often not done, in the interest of saving money. There is nothing that can be done to the cell phone to stop that, regardless whether it's putting out a spurious signal or not. The problem has nothing to do with the cell phone and everything to do with the construction of the phone, though a you mentioned, it could be a bad connection in the land line phone. Again, it has nothing to do with the cell phone. It is possible for a cell phone to interfere with other users of the radio spectrum and the applicable laws specify allowable output of the cell phone to reduce that. BTW a few words about my background. I studied electrical engineering (communications systems) in college and have had my amateur radio license for 37 years. I have also worked in the telecommunications industry, in a technical position, for much of that time. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

What sort of landline *PHONE* were you using? If cordless, .. yes, that is indeed a possibility.

Another possibility with a cordless landline (besides basic defectiveness and/or weak specifications) is if the battery is partially discharged and/or going defective, the lower available wattage could cause the phone's built-in H/W based filtering to start to go "in the tank". Result would also be in line with what you are seeing, and I have observed a similar effect in the past, when one of my cordless phones took a gradual dive.

Its an old cheap phone I got about 10 years ago. It cost me 26DM (~13$US). Over the years I've cut the line and added about 10m to it. I wonder if where I cut it could be the problem. Plus its been dropped and banged around. For the price its a good phone! :)

Is the shielding in the portion of cord you added comparable to that in the original cord?

Ordinary phone cord does not have any shielding. It doesn't even use twisted pairs. Regardless, good cable or not, many phones will detect cell phones. What's happening is something in the phone is detecting (rectifying) the cell phone signal. The noise you here is the pulsing of the cell phone transmitter. This problem wouldn't be so noticeable with the old analog cell phones. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You can hear that even on a wired phone. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
