Hello...
Strange things happens during running this device.
In "stereo mode" i have very much of radio noise in ears, actually i cant find a place and a frequency (within all range) without noise.
In "mono mode" situation is much better, but some little jitters have place. It is very uncomfortable because it hast any logic, even if you stand in one place noise can appear like splash, very loud and short.
I used mei-100 G2 before and the same problems was there, i return them. I thought it was frequency problems, but seems to be not
I tried to use sennheiser omni antenna (460-960 MGhz) but it has no impact on signal quality on any mode.
Next, i just turn the receiver on and hiss immediately going to in-ears. its like white noise on low volume, after i volume up, music covers up the noise, maybe this noise is operational but its very irritative.
I running 3 of shure radio systems ( microphones all of them) and no one of them produces noise on G2 frequencies (830MHZ and above).
i will look forward to other systems like psm 200 or psm300 the others are extremely expensive.
PS all this was because of noise wihtin 653-662 MHz. And also combiner must have for 2 or more devices
