====== Kenwood TH-D72 ======



===== Remote Control =====

The TH-D72 can be used to remotely control a [[public:musings:radio:radio_database:tm-d710| TM-D710]]. This allows remote control of VHF Frequency/Memory Channel, TX power, CTCSS/DCS tones and to enable/disable cross-band repeat.

The remote control function uses specific DTMF sequences to instruct the TM-D710. 

To enable "Remote Ctrl" mode :

  - Select the correct UHF uplink frequency to match the TM-D710
  - Turn off the TH-D72
  - Hold ''MR'' and ''PTT''
  - Turn on the TH-D72

The display will show "Mobile Ctrl"

{{:public:radio:radio_database:2024-03-29_08.46.00.jpg?600|}}

The TM-D710 must also be put in Remote Control mode.

On the TM-D710

  * select VHF mode on both sides
  * turn off the APRS TNC if it's on
  * set the left side to the wanted VHF Frequency
  * set the right side to the UHF Uplink/control frequency to match the TH-D72
    * the first steps are done by selecting ''PM5'' on my TM-D710
    * make sure the left side/VHF is the "active" side by clicking the left volume knob
  * turn off
  * hold ''Rev'' button 
  * turn on

The TM-D710 should now be in remote mode.

To restore normal operation repeat the same sequence of 

  * Turn off
  * Hold ''Rev''
  * Turn on

Successful commands sent to the TM-D710 will receive a "pip pip pip" revertive.

The commands are send using the TH-D72 keypad, remapped as:

|1 = DCS On | 2 = Tone On | 3 = CTCSS On | A = Enter |
|4 = DCS Off |5 = Tone Off | 6 = CTCSS Off | B = CTCSS/DCS Tone |
|7 = Call Ch. Mode |8 = VFO Mode |9 = Memory Mode | C = Repeater On|
|* = Down |0 = Power | # = Up |D = Repeater Off |



  * to change VHF Frequency to 145.500
    * 8 (VFO Mode)
    * A (Enter) 145500 A (Enter)
  * to change to memory channel 2
    * 9 (Memory Mode)
    * A (Enter) 002 A (enter)
  * To turn on Cross-Band Repeat
    * C 
  * To turn off Cross-Band Repeat
    * D

Once the TM-D710 is in the correct condition - VHF Frequency, tone, power, cross-band repeat - it's possible to restore the TH-D72 to normal operation and use it to access the cross-band repeater and use DTMF tones as normal (eg. to control another system via the repeater). Just exit "Mobile Ctrl" mode on the TH-D72

  * Turn off
  * hold ''MR'' and ''PTT''
  * Turn on

You should be back in normal operation mode.

Obviously, to control the TM-D710 again (eg to disable cross-band repeat) simply go back to ''Mobile Ctrl'' mode in the same way, and send the required commands.
