I've recently purchased a Shure UHF-R portable system (UR1M transmitter and UR5 receiver) and I'm using it with a brand new Countryman B3 lav (regular sensibility). RF works fine, but I'm experiencing a noticeable hiss in the audio reception. I've tried with all kinds of gain-sensibility-output level combination, and also tried with various frequencies in non congested environments, but the problem doesn't go away. Any suggestions?
By the way, I'm a newcomer to jwsound and I find it to be an immense treasure of sound knowledge!
