Shure SM58 wireless fault

harpoharpo Frets: 173
hi guys I've got one of these, which seems to be suffering from an intermittent fault whereby the signal from mic to receiver (or receiver to mixer?) drops out momentarily and then is fine again. I've done a bit of looking online and the advice is that it could be a battery issue .......it's not that.
consequently I'm looking for a repair tech .....anyone know one ?

    What model is it ?, there's quite a few versions of the wireless 58

    Have to say the build quality on some of them is terrible. I replaced the on \ off microswitch on one a couple of weeks back and wasn't impressed with the design. 

    Does the signal just drop out or do you hear a burst of noise as well ?

    Ok assuming you can see by looking at the receiver signal indicator  that it is the mic ceasing to transmit a signal rather than the receiver not passing audio then the most likely cause is a bad joint on the mic which would generally mean the mic is fixable for around £50 or it's BER unfortunately in my experience.
    Most of the faults I see with these mics are down to the modular design (heads unscrewing and relying on sprung contacts) crap pin connectors and microswitchs that wear out prematurely.

    If your near enough or can post it to me then I will either  fix it for less than £50 or won't charge at all other than return postage if required.

    Thanks for the response Danny. Shure tech have written back to me saying they’re pretty confident that the issue is caused by it being on the now old frequency.....the same as is used by 3G which unfortunately is subject to quite a bit of interference.
    im guessing the
    at the units can’t be upgraded easily to the new current frequencies ?
