Re: Expanding Function for the IC-V8000.
Following information is regarding the modification of expanding function for the IC-V8000.
Model: IC-V8000 All versions
RX Frequency Expansion:
RX Frequency Coverage After following Operation: 136.000 ~ 174.000 MHz
Procedure of RX Frequency Expansion (For TPE, KOR, AUS model):
Push and hold down the [LOW] and [MONI] keys while turning the power ON.
Note: The USA and SEA versions already expanded for above modification in factory.
TX Frequency Expansion:
TX Frequency Coverage After Modification: 136.000 ~ 174.000 MHz
Procedure of TX Frequency Expansion (For TPE, USA, KOR, AUS and SEA model):
Remove D13 form the LOGIC board to expand transmit frequency coverage above. Note: Some versions already expanded for above modification in factory.
ANI Function: Remove R54 from the LOGIC board to allow ANI function. When use this function, the UT-108 DTMF decode board is required.
Voice scrambler function: Remove D15 from the LOGIC board and cut PC trace CP2 and CP3 to allow voice scrambler function. When use this function, the UT109 (Non Rolling Type) or UT-110 (Rolling Type) voice scrambler unit is required.
Mic gain level: Soldered CP1 on the LOGIG board to increase microphone gain. After soldered CP1, please readjust microphone gain for requirement level.
Wide and Narrow function: Remove R55 from the LOGIC board to allow wide and narrow function. It is possible to switch the narrow deviation in transmit mode without wide and narrow model.
Do not change the D16, D17, D22 and D23 initial matrix diodes on the FRONT board.
