 The new Alinco DJ-160 Radio will receive between 137-174 Mhz, and
transmit in the 2Meter band only (144-148Mhz). A simple modification
to the radio will enable it to transmit in the full range it
receives currently. I have not tested the output power on other
frequencies (Due to my one and only watt meter getting fried)
however I have tried setting a weather receiver a small distance
away, and I did hear the radio in the receiver. To make the mod,
the following must be done: (I assume that you have some experience
with electronics and that you can tell a wire from a resistor, from a
transistor)

1) Take the battery of the radio by lifting the battery release
button. If you look at the bottom of the radio, there will be
a metal plate that is held on with 4 small screws. Take this plate
off, noting exactly how the clip was held on (like the slot for the
battery release clip)

2) On the back of the radio there are two screws that hold the back
of the radio on, take these screws out.

3) Now you should be able to lift the bottom part of the radio by
the battery release button slightly apart. I was told that you
should take the top knobs off, but I found that I didn't have to.

4) If you take the Battery Release Button and turn it about 90
degress, the button should come out easily. After you get the
small piece of plastic that is the button, you should see a yellow
wire behind where the clip was.

5) Take a small wire cutter and CUT this YELLOW wire. You should
probably make sure that the wire doesn't have bare metal showing
from a lousy cutter, because I don't think that grounding this wire
to the case would be HEALTHY for your radio. :-)

6) After You cut this wire. Assemble the radio, and just before you
turn on the radio, do a power reset by holding the FUNC button while
turning on the radio. This will reset the radio to ALL of the
factory set parameters. YOU WILL LOOSE PROGRAMMED FREQUENCIES that
were programmed into the memory mode of the radio, so just write the
frequencies down before proceding with the above instructions.

7) The radio should be just like new, except that the transmit will
be enabled for ALL frequencies! GOOD Luck!

    If you use these mods for ILLEGAL purposes, pity upon thy sole,
for you do not belong in the ranks of Amateur Radio. This
information is only supplied for Legal and Informational Purposes
only and I can NOT be held responsible for anything that you do with
this INFO. And if you screw up your radio, TOO BAD. I can't be
held responsible.

I received your message about the DTMF decoding on the DJ-160, and I thought
I should tell you that the process is not that complicated.
1) Put radio on frequency to catch tones to be decoded.
2) Push the DIAL CH button (lower right corner of keypad) The LCD will indicate
the channel currently selected. The channel must be 3 to decode DTMF. If it
is not Channel 3 then use the M button (top left) to change selected channel.
Once you have the M3 in the window you can push the DIAL CH button again to
bring the display back to indicate the frequency. The word DIAL will remain
in the lower right corner of the LCD window.

From this point on any DTMF will be stored in MEM channel 3, but you can not
recieve DTMF while you are looking at MEM channel 3 , you must be looking at
the frquency being displayed while decoding. To see the decoded data, just
push DIAL CH and read the displayed data. Use the frequency knob to rotate
the stored DTMF tones that do not appear. The radio will store 16 digits on
each transmission, but the window will only show about 6 at a time. As your
message indicated, any new data will over write the old...

For the mod cut the pink wire then hold the "f" and "light" turn the radio on
then back off.  thats all there is to it.
