Objects – english

Using and transmitting objects



  • objects should be transmitted by the nearest digi in the area (which has remote access)
  • object transmit frequency 20-30 min
  • PATH should depend on relevancy of the object. (repeater with large area coverage easily WIDE2-2, local repeater WIDE1-1)
  • Repeater should have symbol "/ r"
  • Name of the object is it’s frequency in following format: XXX.XXXYY
    • XXX.XXX is frequency (i.e. 438.900)
    • YY is shortcut of the area where the repeater is located, example: ST (Středočeský kraj – Middle Bohemia)
  • Text of the object has following format: AAA.AAAMHz TBBB -CCC DDDDDD
    • AAA.AAAMHz is a frequency
    • TBBB is CTCSS subtone (example: for 88.5Hz T088, for 203.5Hz T203, for repeater without CTCSS Toff) where small t switch Narrow (12.5KHz deviation), T is then 25kHz deviation. If we use C (c) instead of T (t), it will switch CTCSS for TX and RX, D (d) for DCS
    • CCC is shift (for -600 kHz -060, for -7,6 MHz -760)
    • DDDDDD is repeater’s callsign

Behind these neccesary fields can be optional text up to 60 characters (but watch out, some TRXs don’t show all)
