ICW2A
Summary: cross-band repeat, extended TX

Modification Instructions for the IC-W2A Handheld

Two mods, one for Cross Band Repeat and one for extended TX range

Cross Band Repeat Function

To access the cross-band repeat function, first perform the extended 
receive mod by holding down the Light/B/# keys while turning on the
power.

To enable cross-band repeat, set each band to the frequency and mode 
desired.  Set the current band to VHF. 

Press (Function-2) (Function-Enter) and the little "L" indicator will
flash.  The radio is now in the cross-band repeat mode.  Do disable,
press (Function-Enter) again.

Extended Transmit Mod

Call the ICOM parts department and order a pair of
MA133 diodes (P/N 1790000850).  These are the three terminal surface
mount diode packages.  It is probably not advisable to substitute 
conventional leaded glass diodes here due to size restraints.

The modification involves removing one surface mount component and
installing two others.  The working parts are extremely small and the
mod should not be performed unless you are comfortable with working
while using a loop eyepiece or other magnifying device.  This is a
"surgical" operation.  Take all the usual precautions with respect to
static electricity, etc.

Remove 5 screws holding back on, and two screws on side of case below
the PTT switch.  Gently pry the unit apart.

Inside the unit are two RF "stack" units.  The complete RF "stack" is
composed of two enclosed sheet metal boxes sandwiched together, about
1.5" wide, 2" tall and .5" thick.  Each RF stack unit (one per band) is
totally self contained, is about .25" thick, and plugs into the
"motherboard" using connectors mounted on one end.

First, remove the stack units.  To do this, remove one screw from each
side of the stack.  Remove the single screw off the bottom end of the
stack and gently remove the metal spring clip holding the stack
together.

Carefully lift each stack unit out by pulling it back and down.  They
should easily unplug from the upper motherboard.  Set them aside for
now.
