Thread-topic: Broad band QRM-500khz

Hello Michael and the group,

It should be a fairly simple matter to build some telephone line low pass filters using a handful of inductors and capacitors and fitting to each line as close to the telephone system as possible. Has anyone on the group made such devices before we re-invent the wheel here?

Hello all,

 

Many thanks to all who responded to my troubles re the above.

 

 

Secondly-- an internal telephone system. 20 line - 4 in use, Panasonic KXT 61610BE—“ Electronic Modular Switching System”

I can only conclude that somehow this wonderful Electronic Modular Switching System is feeding back down the phone lines. I am not knowledgeable enough to know if this is possible but it certainly seems the case.

 

 

PS Anyone know of an internal phone system –QRM free ? or a possible filter solution ?
