Icom IC-28A and 28H mods


If you own one of the IC2A, 3A, or O2AT series Hand-helds,
you may be interested in reading on.  I know my hearing is
pretty good, but have you ever tried to listen to the audio
coming out of your speaker mike on the above ICOM's? For the
most part, it's pretty low.  I may be the last guy to figure
out a cure for this, but here it is anyway.  On the O2AT,
etc., there is a groove on the back near the top of the rig
that is just the right size to accept the HM9 speaker mike
turned 90 degrees so that the mike plug fits in that groove
in the rear of the rig.  Thus alllowing all the audio to be
heard from the internal speaker of the rig, usually much
better than the speaker mike.
Now, in the case of the 2A series, etc., the fix is more
complex.  These rigs don't have that handy groove built in,
so I decided a groove had to be made to accept this
configuration.  I thought long and hard about a minute,
before getting the "Dremel" out and making my own slot or
groove.  It works well on both hand-helds I have.  In fact,
you can hook up an external speaker for even more loudness in
the auto.  So, give it a try or see me for a demo.
