mobile telephone noise while recording a DVD

[micha]

hi.

i dont know why it was recorded,
but

-the mobile telephone was 1meter far away from the VHS player and DVD recorder.
-the DVD recorder is on the VHS player
-i got no SMS, or a telephone call, when the noise was recorded!!!!
- i never got this noise before, when record a DVD ((

does anyone know other reason why, and which source this noise has.

i tested it: recorded a DVD, and while that, i placed the mobile telephone at the same place as before, and phoned me on my mobile.
but the noise dont appeared . *?*

and i remebering , some months ago, i had this noise, when:
-record from VHS player (3Meters far away) to TV-card (PC)
-the mobile tel. was placed next to the PC-monitor
-the speaker and monitor was running.

the noise was cause the speaker, i though.

mobile upset amplifiers. this can be an audio amp or a video amp. sometimes the phones do "touch base" even when you have no calls or no messages. sorry, part of life these days

Mobile phones, at least mine, continually communicate to find the local cell towers. Mine checks every few seconds. Just keep it away from your cables and computer equipment. A few feet should be plenty.

WOW every few seconds??? mine checks every few MINUTES or so.

but i do agree just keep it away a little and all should be ok. mine is always on me and i have never had a problem.

I think the amount of times the phone contacts the base is dependent on the signal strength. Sometimes, if you are in a position between 2 bases, the phone will change base as the signal strength varies. If you are in a strong signal area the phone will not contact base.

Mine is a 3 Watt 'bag' phone that runs off the vehicle battery. This is a very hilly area and if I have 3 'bars', it's a good enough signal. I have got RF interference in my computer (cable modem) on occasion when the Sheriff's Dept. transmits under the cable TV line outside. Fortunately not when I have been encoding. The HF transciever in my pickup (150W) does the same, so I try not to use it by the cable line. The cable company says they don't have a problem with their line.

thx for replies.

i have a Siemens MC60.

hm, i test the follow:

-recording a DVD from VHS while trying manually find local cell tower.
-mobile tel. was placed far away (1 meter) from VHS player, and then near VHS player.

but while find local cell tower , no noise appears.

but the noise appears when i got a SMS, or a tele. call,
when i place it near at VHS player.

now. i have just this reason for the noise yesterday:
that a mobile tel. doenst use the same frequen to find local cell tower.,
