    Default I thought I was hearing baby aliens!

    Yes... They are out there! - Well, something was up but maybe they were little green men trying to tell me something.

    I turned my phono stage on yesterday and something very strange.. a pulsing noise, rythmic and almost like a ZX Spectrum loading. Checked everything... even turned the fridge off but the strange pulsing was still giving me grief.

    After everything off in the house apart from the baby monitor I was at a loss... so as a last shot at trying to stop it I turned the baby monitor off to my amazment the aliens had Eff'ed off to another world.

    So, just to let you know, baby monitors and phono stages don't really go together.

    Is the baby monitor 'wireless' or linked via the mains? Either way I'm not entirely surprised.

    Have you ever left your mobile phone (switched on) near the record deck and/or cabling of the phono input? You can hear some strange noises if you do!

    Regards

    RFI, radio frequency interference. It may be low powered but in reality it's always best to keep as far away from any radio transmitter as possible, even if it's probably less than 1 watt like that baby monitor

    No mobile phone here, ethernet is wired... Nothing transmitting, i think you get the picture

    I used to hear what sounded like Russian radio late at night from my phono cables in the mid '80s (m/c cartridge) - very quiet, only with no record playing and the volume turned up - but I was in the middle of Warwickshire - just occurred to me - perhaps it was a BBC russian language service from Daventry/Rugby?

    Why do I get the impression that this isn’t going to be a topic Marco will be participating in a lot.
