    <p>Keep in mind to also not run afoul with legislation. That might
      seem to be about emergency use (UHF 5/35) or telemetry (UHF
      22-23), but using simplex on the input frequencies of UHF
      repeaters (31-38 & 71-78) that one is within the operational
      range of is not allowed. Many contract roadwork gangs for example
      use these and jam repeaters up.</p>
    <p>There are also roadsigns out in country areas that suggest 5/35
      for general information rather than the legislated "emergency use
      only".<br>
    </p>
    <p>Suggesting one be careful creating features that specify these
      channels.</p>
