網路找的, 參考之! 英文請自行找谷歌喔!!
The TM-241a is capable of transmitting from 136 to 174 MHz when the following modification is performed. The transmitter specifications will vary from published in-band specifications. Remove the top and bottom covers from the transciever. Remove the knobs from the front panel. Remove the nut from the mic jack and the nut from the channel selector switch. Remove the 4 screws that secure the front panel to the body of the transceiver. Pull the front panel off the transceiver to expose the Control board. Remove the 3 screws from the Control board. Gently pull the board off the transceiver. Remove the diodes and resistor as on the two pictures Reassemble the transceiver by reversing steps 1 - 6. Reset the microprocessor by holding in the MR key as power is turned on.
It is equvivalent if you remove the diode D206 or R220. It is placed in line by D207 and D208.
