TELEPHONE INTERFERENCE |
|
|
|
When you have interference on you'r telephone you can do some things by you'r self. Make sure that your radio cable conections are good ,good means best coaxcable ,good connectors ,swr at lowest point. Antenna free in air. and a low pass filter between your radio and your antenna. |
|
|
|
If you have this don then you are on the good way to solve the problem |
|
|
|
But when you stil have interference you have to look into your telephone system |
|
|
|
Are u using twisted shield protecting wiring if not replace them from al your machines : answeringmachine ,modem ,fax ,alarmsysteem etc. ect. |
|
|
|
If you have than still interference look in your toolbox for a ferrite kern or ring or buy some in your local radio store or maby you have a old transistor radio there is insite a ferrite antenna take him out than you can use this ferrite for the next thing. |

Twist the cable from you telephone some times rond the ferrite and make sure that it is stick's at close to the telephone, do that the same by al your machines fax modem ect. Ect |
|
|
|
Then look if you have still interference if not you'r happy person |
|
|
|
is there still interference then you have a problem than there is for me nothing what I can do . |
|
|
|
what you can do is go to the phone company explane what you have done and maby that they have a solution . |
|
|
|
you can also write to the manufacturer's company where your telephone product is coming from and ask if the telephone deals with the FCC regulations aboud interference . |
