Weird. Cordless phones do come in different varieties. If you have the 900mhz flavor, try the 2.4 ghz flavor (be careful of interference with wireless computer network, however). Or try the 5 ghz flavor.
I have a feeling that Eric is correct. The 2.4 ghz cordless phones are notorious for generating interference, especially with microwave ovens. I have experienced that myself, and now only allow the 5.8 ghz phones in the house. The 900mhz is a solution as well, though the range is not as good as the 5.8 ghz models. I believe that there was an article about all of this in "Consumer Reports" a few years ago.
First did you switch the amps and did the static go to the other speaker?? If so, it is in the amp, if not... keep switching IC and PC, if it never switches, call the electrician.
Drtmth58, as for rage I must differ, I have found as each new cordless phone comes out touting better range the range actually diminishes. My older 900 mHz phone would work fine on the beach from my condo, when I 'upgraded' to a 2.4 GHz, it no longer worked on the beach. When I bought my house (sorry to lose the beachfront but..) I got a 5.8GHz phone, damn thing doesn't work in the driveway!!!
I did switch the amplifier but the static remained coming out of the same speaker. When I sent the one amplifier back to the manufacturer, in the interim I ran the remaining mono amplifier and an old mono amplifier I had lying around and never had the static problem. Now the mono returned from the manufacturer and the problem returned.
All the problem phones are 5.8GHz.
So do people think I should call a electrician or someone to look at the phone wires in the wall?
This is not your first post regarding your static problems. I have no idea whether it's related to your phone system or not, but I would recommend that you contact a few local recording studios and find out who does their electric work and have your house wiring thoroughly inspected. Most electricians haven't a clue about audio equipment. Maybe an electrician who has worked on studios will at least be more open to your concerns.
Have you tried unplugging the A/C on the phones? You may need a line conditioner or better ground to eliminate this. Are your phone plugs 3 prong? Try a cheater (3 prong to 2 prong adaptor) to avoid ground loops. Your phone system may be grounding itself in the same place as your electricity???
Even relocating the phone bases to the other side of the house to utilize circuits on the other side of you fuse box may do the trick.
My electrician would be lost if you called him with this problem...
Last year, we had a problem with our phones (both cordless and corded). We would often not have a dial tone, and on more than one occasion would pick up only to hear neighbors conversations (even on wired phones). After several calls to our phone provider they agreed to come out--turns out there was a problem with the common connection for the cluster of houses that was related to a bad ground of the phone circuit. Since your issue seems "internal" it might be worth just checking the integrity of the connections between your house and the incoming phone interface. Ours is outdoors and subject to the elements which is never a great environment for connections.
