Cordless phone microwave interference

the kitchen. When the microwave is run the static on the line is so
bad it usually drops the connection. Has anyone else experienced this?
I'm going to try relocating the base but that is undesirable for
access. Is there a filter that can go on the microwave or is the
microwave or phone broken?

people that love to solve this type of problem. It's called Electro
Magnetic Interference or EMI for short.
Good luck!

locate where your microwave is leaking! You can also compare it with your
neighbor's microwave and see if the leaking is not excessive. Also
relocating the base far away from the microwave (especially behind some
metal) will certainly help.

Larry,
Before doing anything suggested so far, try 1 simple thing. Plug the power supply for the phones
base unit into a long extention cord and plug the extention cord into a wall socket in another room
as far away from the microwave as the cords length allows. Then test to see if the static is still
there when the microwaves on. It's quite possible the Microwave's plug and your phones plug are on
the same circuit and this is where the static is comming from. I have a BIG old microwave thats 15
years old and 800 watts and it doesn't interfere with my old AM cordless phone or my 900 mhz
cordless phone. If your microwave is leaking rf energy that much I think you'd know.

There's a big difference between a 49 or 900 MHz phone and a 2.8 GHz,
in terms of susceptibility to microwave interference. Microwaves run
at about 2.4 GHz, as I recall, which is much closer to the 2.8 GHz
phone frequency than to 49 or 900 MHz. Personally I'd vote for moving
the base unit away from the microwave.

How could you tell -- when you feel your brain getting hot? :)

GHz. Some of the microwaves will inevitably leak out, could be yours is
leaking too much, it's hard to say.

install the base unit within 8 feet of microwave ovens, radios, televisions,
and computer monitors. It seems the simple fix is to move the base unit.

Neither is "broken". The name of the oven is a *microwave* oven. The
phone range, 2.4 GHz is in the *microwave* range. Both are FCC Part 15
devices which must accept interference from properly licensed devices
and both must not be used when they interfere with other devices. Since
you own both it's easy. Stop using the microwave when you're on the
phone or stop talking on the phone when you're cooking with the
microwave. You need to separate the devices as much as possible.

What are these FCC weasle words really saying? "Device _may_ not cause
interference" and "Device _must_accept_ any interference, including
interference that _may_cause_ undesired operation of the device".

It means that if you screw up someone else's device with this, you have to fix
it,
but if someone else's device screws up yours, it's your own damn problem.
