Icom IC-W32A Mod



Expand Frequency Coverage on TX/RX for the Icom IC-W32A/E

NOTICE: We can not guarantee specifications beyond the amateur bands. Not responsible for any damages incurred in attempting this procedure. This modification may void all warranties.

1. Remove the battery.

2. Remove the 4 screws holding the rear cover and the 2 lower screws holding the shield in place in the battery compartment. 3. Carefully lift the rear cover with the battery comparment shield away from the front cover.

4. The front and rear sections are connected together with a flex strip connector. Carefully lay the rear section aside by lifting upward, turning and laying the rear section over away from the front cover leaving the flex strip connected.

5. With the front cover section in front of you, antenna connector to your left, locate the notch at the right side of the exposed PC board. Next locate the three, 3 terminal diodes near the lower corner of the notch. Two are in line from left to right, with the third below the diode to the right. This last diode (the one below the right one) is diode D523. Very carefully remove D523.

6. Reassemble the radio in reverse order.

7. Perform a system reset by holding down the Squelch button (on the side) and the Band button while turning the radio on. Note that all memories will be erased, so write down anything you want to save and reprogram.

VHF coverage will be from 140 to 170 (plus or minus a bit) on Tx/RX
UHF coverage will be from 430 to 470 (plus or minus a bit) on TX/RX
