-------------------------------------------------------------------------------
KENWOOD TM-721A WIDE BAND MOD
-------------------------------------------------------------------------------
To modify the 721, remove the top & bottom covers.
Remove the 2 screws on each side that hold the front panel to the main unit.
[You can just loosen the bottom 2 screws, 1 on each side don't actually remove
them.
Then remove the 2 screws in the top center & bottom center that hold the display
to the main unit (all silver screws, not the black ones).
Now you can swivel the panel out & down.
Look at the back of the display unit. To the left of the Microprocessor near
the lithium batttery you will see 3 chip resistors in a pattern like this:
H= chip resistor
X= blank space
--------------------> H X H H
add a jumper (or ideally a zero ohm chip resistor where the X is.
Hold the F key while turning the radio on.
The display will go from: 100 - 200 MHz on VHF
400 - 500 MHz on UHF
WARNING!!!
Remember to write all your frequencies down before you start because you
WILL lose them on both bands once you add the jumper even if you do not reset
with the F key.
