Since most of us use their Transceiver also as an Signal Transmitter here the way how to extend the FT-1000MP MARK-V, only by pressing switches and keys it really is a few seconds job!
Press the POWER on while pressing FAST and LOCK switch “gives you an extended menu up to 9-9”
Press the ENT key while pressing the FAST switch “gets you into the menu”
Turn the VRF/MEM knob up to Function number 9-9 = selection name “t-SELEct”
Turn the MAIN VFO counter clockwise till you find at the very end “Gen” and press the ENT switch.
