YAESU FT-11 R

To extend the transmit range, you need to remove the solder jumper across jumper D on the controller board. This modification requires opening the radio and carefully desoldering the jumper. You should then reset the radio using the MHZ/ and MHZ/ buttons to activate the extended transmit range. Refer to the viewed document for detailed instructions on opening the radio, locating the jumper, and resetting the radio.

The viewed document explicitly states that the author takes no responsibility for any damage caused by the modification. Therefore, proceed with caution and ensure you understand the risks involved. It is highly recommended to consult with a qualified technician before attempting any modifications.

Yes, the Yaesu FT-11R has a Clone feature that allows you to transfer all memories from one radio to another. To do this, connect the two radios using a cable with two male stereo 1/8” connectors, and connect the top (ground) and middle conductors of the plugs straight through. Then, on each radio, hold down the FM button while turning it on. On the receiving radio, press the MHZ/ button to see RX CLN. On the sending radio, press the MHZ/ button to see TX CLN, and the receiving radio should return to normal operating mode after a few seconds. Please note that the memory transfer will overwrite all memories in the receiving radio.

The viewed document describes the functions of some of the jumpers on the controller board, but not all. Jumper D is used to extend the transmit range. Jumper A turns the radio into the euro version, and jumper E turns it into the 440Mhz version. However, the functions of other jumpers, B, C, F, G, and H, remain unknown. It is important to note that the information provided in the viewed document may not be exhaustive.

To reset the microprocessor, press and hold the UP and DOWN arrow keys while turning the radio ON. This will reset the radio to its factory settings.
