IC-746 Mod.

Remove the twelve screws holding on the bottom cover.  With the Radio
laying flat on it's top remove the bottom cover.  Turn the radio so
that the front panel is to your left and the antenna connectors are to
your right.  Locate the IC labeled "ICOM HD6433042SF".  About 3/4 of an
inch to the right is a vertical row of diodes.  The left hand column of
diodes has 7 diodes (14 possible spaces).  The right hand row is full
with 14 diodes.  Remove the diode in the 6th space from the top in
the left hand column.  DO NOT remove anything from the right hand
column.  This should get you TX from about 100KHZ to 60MHZ and 118MHZ
to 176MMZ.  Do this totally at your own risk. Never, ever transmit out
of the ham bands or your privileges..
