IC02AT.8
The ICOM 02-AT 2 meter handheld will go into the 150 MHz
range with some modification.
On the ICOM 02-AT, as well as on the ICOM -4-AT for VHF
and/or UHF work, both units require semi-major diode surgery
for frequency expansion. For VHF, two diodes are removed and
three are added for the ICOM 02-AT to extend all the way up
to 165 MHz. For UHF work, two diodes are added to extend the
range of the ICOM 04-AT. The modification is tricky, and a
bit complicated.
On the brand new ICOM 735, to unlock the transmitter, you
simply cut diodes D33 and D34 that are standing on end near
the microprocessor section toward the rear top of the radio.
On the IC-745, locate the RF board on the side of the radio
and cut the light brown wire at jack 7, which is going to pin
1. Your transmitter is now unlocked.
On the IC-751, locate the RF board on the side of the radio
and cut the black wire going to pin 1 of jack 2. Your
transmitter is now unlocked.
