  1. Remove the top and bottom covers of the transceiver.

  2. Remove the final power amplifier module.

  3. Locate the LOGIC-UNIT on witch there is a back-up lithium battery for the RAM memory.

  4. On the LOGIC-UNIT, near the chip called IC6 (TMP82C265BF-2),between the output pin PC06 and the imput pin PA15, find the diode D3.

  5. This diode is not an SMD component.

  6. Cut the diode D3.
..Now the ICOM IC-737 will transmit from 1,6 to 30 Mhz !!!.
