how do you know which one is which
just wondering if there is a simple way to identify which one is which. is it as simple as just not working or a low volume or something like that. for example would it be possible that an R44 that has had other radios and nat boxs fitted somehow have wound up with a low impedence setup instead of a high.
we operate Robinsons and Bell 206's, are we lucky enough that they are common impedance. cheers
