        If batt_volt >= 12.4 Then 
          SW12(1)
        EndIf
      EndIf
      ' if the battery voltage isn't too low, turn the radio on daily.
      If TimeIntoInterval(720,1440,min) Then
        If batt_volt >= 12.2 Then 
          SW12(1)
        EndIf
      EndIf
      ' if the radioflag hasn't been set manually then turn the radio off 10 minutes into the hour.
      If TimeIntoInterval(10,60,min) OR commscomplete = true Then
        If radioflag = false Then 
          SW12(0)
          commscomplete = false
        EndIf
      EndIf      
      If batt_volt < 12.6 Then radioflag = false

A further modification would be to make the TimeIntoInterval commands use variables for the on & off times.
