Icom IC-2710H (IC 2710 H IC2710H) transceiver mods reviews software and diagrams

Cross Band Repeater Mode:

• First, verify D-139 is not present (for non USA Versions only)

To ENTER Cross Band Mode:

• Set the desired frquency, tone, & offset on both bands
• Press [VHF} and [UHF] main knobs and the [SET L] key at the same time (An "L" will appear on the display)
• For zero hang time, also press the [LOW] key with the above three key command.

To EXIT Cross Band Mode:

• Press [SET] to exit Cross Band Mode

Remote Operation (UT-49 DTMF Decoder Unit Required for Remote Operation)

1. Set the sub band frequency to receive a control signal (DTMF code).
   • The optional tone squelch function can be used for the sub band to increase remote control reliability.

   Password Setup
   
   

2. Program a 3-digit password into the sub band's code channel 5, if desired: (default is 000)
   1. Push the desired band's tuning dial.
      *Each band has separate code channels.
   2. Push [DTMF] 2 times to turn the pager function ON.
      * "P" appears in place of the 100MHz digit.
   3. Push {(VOL)SET] to select the code channel setting display.
   4. Rotate the selected band's tuning dial to select the desired code channel, 0-5.
      * Code channel P cannot be used for programming.
   5. Push [(SQL)MONI] or [(VOL)SET] to select the digit to be programmed.
   6. Rotate the selected band's tuning dial to set the digit.
   7. Repeat e and f until the last digit is programmed.
   8. Push [DTMF] to set the code channel for "receive inhibit" or "receive accept."
      * When "receive inhibit" is set, "SKIP" APPEARS.
      * Code channel 0 cannot be set as "receive inhibit."
   9. Push the selected band's tuning dial to exit the setting display

   Remote Operation Continued (UT-49 DTMF Decoder Unit Required for Remote Operation)
   
   

3. Select the main band by pushing a tuning dial, then set the desired frequency for operation.
4. Push [DTMF] one or more times unil "REMO" appears to select standby for the remote control.
5. Set the operating frequency of the controller transceiver equal to the sub band frequency of the the IC-2710H.
   * Make sure a tone frequency is set when using the optional tone squelch function with the IC-2710H.
   * The external DTMF remote does not accept a control signal on the main band frequency.
6. From the controller transceiver, transmit the DTMF code as follows:

       ENTER REMOTE MODE "REMO":       B+XXX (password)+#
   
       X-BAND ON:              B+XXX(password)+#+DB*
       
       X-BAND OFF:             B+XXX(password)+#+B*
       
       EXIT REMOTE MODE:       B*
