Stuart91 Posted June 6, 2017 Share Posted June 6, 2017 Had a bit of a strange one at the weekend. A handheld Shure ULX transmitter started giving us bursts of static. They were coming in steady pulses, there was a definite rhythm to them. The mic had been otherwise flawless all day. Swapping the speaker onto a spare (identical) mic on a different frequency seemed to solve the problem. We were left scratching our heads and the only difference we could see from other people using the same mic was that this guy had a Smart watch, and he was wearing it on the same hand as he was holding the mic. Now, I know that the watches use bluetooth for most things, and I wouldn't expect anything happening in the 2.4GHz band to affect radio mics in Ch38. But I could well be wrong, or there could be some other function of the watch that is more problematic. Has anyone else had similar problems? It would be a pity if we had to start checking users' watches, in the same way as early Blackberries had to be confiscated... Link to comment Share on other sites More sharing options...
peza2010 Posted June 6, 2017 Share Posted June 6, 2017 You didnt happen to see if it was a "Decent" watch or a cheapo watch did you? Could be something as simple as the factory in china not being bothered to put an RF cage over the electronics. Link to comment Share on other sites More sharing options...
Stuart91 Posted June 7, 2017 Author Share Posted June 7, 2017 I don't think it was an Apple Watch (based purely on my suspicion that anyone who owns an Apple Watch will call it by its proper name). So it could well have been a cheap one. Link to comment Share on other sites More sharing options...
vlfaudio Posted June 15, 2017 Share Posted June 15, 2017 I had a similar issue the other week with Sennheiser ew G3 kit. Was using a beltpack to get audio to an outdoor courtyard ( not my idea ) , client called up getting static everytime someone walked past the reciever. I strongly suspect 4G phones are the culprit. Don't have a link to hand, but read an Ofcom report where interferance from 4g had been shown to cause some units to fail scan within 7 metres.

sunray Posted June 15, 2017 Share Posted June 15, 2017 I know its obvious but I assume these interference issues are not ch69 kit. There's still loads of it in use where some users are oblivious to the changes Link to comment Share on other sites More sharing options...
