  1. Is it possible to deactivate four channels so just one is available? I only need one channel without my family bumping the knob to a different channel.

          1. What about activating Scan and only choose ADD on one channel and REMOVE on the other four channels of the RT27V?

  2. Hello,
    I was wondering if you have a link, to the programming software, for the
    RT27V MURS radio, I can’t seem to find it on your website?

    1. Click the “support”, then click “firmware/software”
