First remove the nine screws which fasten
the top cover of the radio. Do NOT remove the four screws
which secure the speaker to the top cover.
Carefully remove the top cover.
Unplug the speaker wires connector from the board and put
the top cover aside.
Find silk-screened characters
UT-102 at front edge of board. Immediately to the left of
these characters are 14 pairs of pads for a diode matrix.
The radio comes with diodes installed at pair 1, pair 6,
pair 8 and pair 11, counting from right-to-left, beginning
at characters UT-102. Rigs delivered to non-USA/CANADA
destinations may have a different complement of diodes in
this matrix.
Remove the diode at pad pair 6,
again, counting from right-to-left, beginning at characters
UT-102. You are now finished the 60-metre transmit mod.
Plug speaker wires connector back
into board.
Re-install top cover and secure with nine screws making sure
not to over tighten.
That's it. Now do a full reset of rig.
FYI: the diode removed is D5806,
whose anode connects to IC5901, pin 55.
Please be careful not to apply to
much heat when removing diode from the circuit board as
damage may occur.
