thought I would share info on:

1.) Extending the receive range
2.) Adding an 800 Mhz antenna input
3.) Cross-band repeat instructions (local and via remote control)

EXPANSION OF RECEIVE RANGE

The following diodes are located on the Logic Unit circuit board.  The
Logic Unit circuit board sits behind the front panel of the radio.  To
get to the board remove the top and bottom of the case.  Now notice that
the front section of the radio is a separate unit from the main body of
the radio.  Remove the 4 screws holding the sections together but do not
yet separate the sections.  Place the radio on a table so that it is
right side up.  Carefully start to separate the sections being careful
of ribbon cables that connect the front section of the radio to the
rear.  If you look at the back of the circuit board on the front section
towards the lower part of the radio, you will clearly see three glass
diodes labeled D8, D9 and D10.  You will know this is the right circuit
board because a lithium battery will be taped to it.  These are the
diodes to cut to get extended receive range as follows:

D8      320-399, 830-950        800 Mhz coverage requires new antenna input
D9      118-135
D10     400-479
