Walker High-Def Links v. Cell Phone EMI-RFI

Do you think the cell phone transmission that causes the electronic sound through speakers is in any way similar to any RFI that would be caused by a microwave, laundry machine or TV?

I have no clue on electromagnetism: I'm an English major.

I do have the Walker Ultra Links on my speakers. The speaker cable length is 25 feet from my SET amp tp my horn speakers. I just made a call on my cell phone next to the speakers- no sonic difference while calling. The Walker's did make a significant improvement in the system's sound.

David, your experiment concludes nothing.

Why?

1) You did not try the experiment with and without the Walker links
connected.

2) You (we) do not know that making a call causes the pulsating sound
described by Somut. I have experienced the sound he is describing, and never
was it the result of making a call on a cell phone. However, the sound was
always caused by a powered-up cell phone sitting idle within about ten feet
from the electronics.

3) From my experience with this phenomenon, proximity to the speakers is
not the cause. Proximity to the electronics is the cause.

I will go out on a limb and venture a guess that in Somut's system, under the
conditions in which the cell phone caused the vibrating sound in his
speakers, the Walker Links would have absolutely no effect in eliminating the
sound.

The sound of cell phone going trough speakers is strictly a 3G network thing. Lots of phones including Blackberry, Treo and iPhone run on this network and when they "check in" with the system there can be a broken buzzing through the speakers.

The problem is not with the speakers nor is it effected by the Walker High-Def links one way or the other. The interference travels in from the front end of the system and moving the phone away from the system (physical distance) is the way to resolve the problem.

If you own a cell phone that does this with your sound system, set your phone beside your computer and your computer speakers will buzz at the same frequency and interval. Although the FCC states that no device may interfere with another, this whole new cell phone network plays havoc with dozens of pieces of electronics, not just high end.
