Thanks for your response
Sadly I do not have the equipment to analyse the transmitted frequencies.
I know from a friend at another production company in town, that they experienced similar problems at an outdoor event a few weeks ago.
The frequencies used by the IDX Transmitter are between 2,1 and 2,8 Ghz. The wireless standard 802.11 N uses nearly the same spectrum. Maybe due to the increasing usage of this standard in homeuse and with mobile phones we get these problems? I can not explain it because i am not an expert in wireless communication…
Really I am at the point of giving up to fix the problem but just want to try to understand it.
