Icom IC-756 PRO II (IC 756 PRO II IC756PROII) TX mods 100 Khz - 60 MHz

  • Open the IC-756PRO mods article

  • look at the picture, it is similar for PRO2 model.

  • Remove only two lowest diodes marks as D3751 and D3752.

    Reset is not necessary.
  • Done!

Now IC-756PRO2 will transmit from 100 kHz to 60 MHz without any gaps!!! Dunno about RF power on 136 kHz, could be it possible, anyway be carefully with transmitting lower than 1.8 MHz. Enjoy.
