New mics are always a good idea anyway
Hehe...yeah...there is a small chance that all of this is actually an elaborate plot to psychologically justify that I must have new mics. To quote a fine 'made in australia' film..."there is no spoon"...
I'm not sure if it's GSM but there used to be a protocol where the tower would commuinicate with the phone even when it was switched "off".
Thanks for the thought...I've read the same thing somewhere, but I'm 99% sure that's not the case with the aussie phone network and is not the source of at least the rfi i get on my recordins. My reasoning:
a) I've never had speakers suffer from rfi while our phones are off (while its a fairly common occurence when phones are on)
b) usually when my recordings have rfi i hear it over my monitors and can place it to some wook within a few meters of me clicking ''send' to make a call or send a txt msg
