This has been doing my head in for along time now and i have been in over the last couple of days and in bed so its REALLY been annoying me... Basically i get a lot of interference from my phone through my alarm clock. Its a Iphone/ipod charging dock but i generally dont use it for charging as i always have a case on it and its a pain removing the case when charging etc..

Is there anything i can do about it? Although not a light sleeper it often wakes me up. I am pretty sure i have also tried switching everything off at night except for normal data (Phone Calls and texts) but i still get interference.. Its driving me nuts..

Help!

You can get some Ferrite Cores to put around the speaker wire inside the clock.

The strange thing is interference for me only happens when I'm using a GPRS signal. A 3G or Edge signal doesn't create any interference.

I get the same with my Blackberry on GPRS or Edge. 3G and it's fineee. Odd.

Happens with all phones, and always has. Ferrite cores can help, as can adding shielding. With my limited radio knowledge, I suspect that 3G does interfere just the same but the modulations are, by necessity, higher frequency and thus much less likely to be audible.

I get this in the car, when the iPhone is plugged into the stereo. Quite annoying.
