Icom IC-725 (IC 725 IC725) Enable preamp below 1.5 mhz

  1. Remove bottom cover.

  2. Locate Q12 on Main Unit. 1/3 way from left side of board. Q12 is the transistor that bypasses the preamp below 1.5 MHz to avoid overload when listening to AM Broadcast Stations.

  3. Clip the lead of Q12 closest the front of the radio.

  4. That's it, the preamp will now work below 1.5 MHz!
