    I hope you are fine. We use RVR 1kw transmitter. We use Ba1 as MPX. Our transmitter’s output switch is in Mono..Can we change it to Stereo? What do you think are the positive and negative effects?

    Well, the MPX signal is a L/R composite, so, if the input is stereo, the output will also be stereo. You will need to ensure that your deviation is within legal limits, of course, so you may have to tweak a preset to suit your format.

    Thank you for your reply. Which one do you recommend? Is it Mono or Stereo? For example, if we set it to Stereo, we can use MPX again, right?

    The MPX signal can carry the full FM bandwidth, whether mono or stereo. If you can switch easily between the two, why not try it on an experimental broadcast? In stereo, the 19 kHz pilot tone should automatically be generated, and stereo receivers should then respond to that.
