-
Remove any diode position on D6
-
Install diode DA (code No. 1750000160) position D6
After this modification frequency lock range will be expand typicaly :
RX (MHz) : 108 - 140 (AM) , 138-169 (FM) , 310-370 (FM) ,
TX (MHz) : 139 - 163 (FM) ,

Yeah, the above is crude, just meant to give the relative locations of the
mysterious diode, SP1, R38, R39, R41, R42, R43, and R61. The 3-terminal
box with an arrow drawn to it (the arrow is in the original image) looks
like the below. A diode is connected from the lower left tab to the upper tab.

diode matrix programming
To simplify/fool-proof this, if the schematic has:
(X) --->|--- (Y)
I'll say "from X to Y". From the "IC-2SAT IC-2SET SCHEMATIC DIAGRAM":
Japan Version D6: DA115 from KEYI2 to KEYS2
Europe Version D5: DA115 from KEYI0 to KEYS3
D6: DA115 from KEYI2 to KEYS2
Italy Version D5: DAN202U from KEYI1 to KEYS3 and
from KEYI0 to KEYS3
D6: DA114 from KEYI0 to KEYS2
U.S.A. Version D4: DA115 from KEYI2 to KEYS3
D9: ISS254 from KEYI1 to KEYS2
Australia Version D5: DA114 from KEYI1 to KEYS3
D6: DA115 from KEYI2 to KEYS2
Asia Version D4: DA115 from KEYI2 to KEYS3
