Kenwood markets this radio worldwide, and has made provisions to allow the radio to transmit between 1.625 MHz and 29.999 MHz.
The All-band transmit modification requires the removal and re- location of a diode on the digital board which is located behind the front panel. The US version of the radio has diode D11 installed, and diode D9 removed. D11 must be removed, and installed in the D9 position. This modification IS NOT for the faint of heart, as it entails removing the front panel, and the digital board. Note that the digital board has solder holes that are through-soldered; that is, there are circuit traces on both sides of the board, so make sure that ALL solder is removed from the holes. This modification will also allow the antenna tuner to tune anywhere the receiver is tuned. This modification should ONLY be performed +??y those familiar with soldering and de-soldering techniques, and requires patience, and dexterity.
