This mod expand the frequency range to:

TH-F6A can receive 142-152, 216-235, 420-450 MHz on A-band.
TH-F6A can transmit 137-174, 216-235, 410-470 MHz.
TH-F7E can receive 137-174, 410-470 MHz on A-band.
TH-F7E can transmit 137-174, 410-470 MHz.

First remove the grey plastic Mic speaker Cover on the side of the radio (trust me if you forget it will be impossible to get it apart!).
Then the ant. and the vol tunning knob and the nuts below then, take the battery off and remove the two screws below the battery pack.
Take the cover off very slow cause you damage the speaker wire if you mess up and go fast!.. You can leave the speaker connnected, just push the top part off to the side very gently!

Once in the radio look over to the left side below the Mic...

You will see a series of three diodes remove the top one (See photos)

Look below the last diode and you will see a chip resistor (See photos)

I heated them very quick and placed a thin jewelers screwdrive under neeth and it came right off the board.
