 ------------------------------------------
 
 
 First remove all black screws from the rear case and top panel. Remove 4
 silver screws holding the battery connector on the bottom. Remove the 3 knobs.
 Carefully separate the front and rear cover. There is a multiconductor trace
 between the front and back. Keep care with it !!! Looking at the "CONTROL
 UNIT" board, you will see 8 solder jumpers half hidden by a cover plate and
 the multiconductor flat cable. Remove the solder from pad 1, 2 and 4. Place a
 solder on jumper 3. Don't change other jumpers. Close the radio. Now when you
 turn on the radio it will come up with 1.000 in the display. Memory channel
 should say "1". Program in the lower receive frequency. Exemple 135.000 MHZ
 then push VFO key. The Memory channel should go to "2". Now program in the
 upper receive frequency. i.e. 185.000 MHZ and push VFO key. Memory will move
 to "3". Do same for lower and upper transmit frequencies.
 
 
 For FT811 do the same as above and program i.e. 420 to 460 MHZ.
 
 
 If you need to reset or reprogram do like following:
 Turn power OFF, press MR, 2 and VFO at the same time. While holding these
 buttons, turn power ON and restart programming.

Hello, TNX for reading this MSG. I hope it can be usefull.

To allow this TRX for a VHF UHF general cover, do the following mods :

  1ø) Remove the front panel.
  2ø) Look for the first part where the Lithium battery is connect
 

  there are 8 connectors like :

  ÜÜ Ü Ü Ü Ü Ü Ü Ü Ü                        ÜÜ Ü Ü Ü Ü Ü Ü Ü Ü 
  ÛÛ Ü Ü Ü Ü Ü Ü Ü Ü   ---------->  FT-411  ÛÛ Ü Ü Û Ü Ü Ü Û Ü
     1 2 3 4 5 6 7 8                           1 2 3 4 5 6 7 8



                                            ÜÜ Ü Ü Ü Ü Ü Ü Ü Ü
                       ---------->  FT-811  ÛÛ Ü Ü Û Ü Ü Ü Ü Ü
                                               1 2 3 4 5 6 7 8


 To validate the micro controller, do next :

  For the FT-411 :  RX 120 - 174 Mhz     TX 140 - 174 Mhz

     1ø) Reset the TRX by switch on it with [MR] and [VFO] key down.
     2ø) Type  1200 [VFO]  1740 [VFO]  1400 [VFO]  1740 [VFO]
     3ø) Press the [F] and [7] keys tho change the QSY step.

  BE CARREFULL, with this few mods, the TRX looses the automatic AM detection.


  For the FT-811 :  RX 420 - 470 Mhz      TX 420 - 470 Mhz

    Do the same but step 2 is different :

     1ø) Idem
     2ø) Type 4200 [VFO]  4700 [VFO]  4200 [VFO]  4700 [VFO]
     3ø) Idem


    Good QSO's...
