I was asked about modification of the DJ-580 for out of band operation.
They couldn't have made it much easier:
- Remove battery pack.
Use a small philips screwdriver (ie. jeweler size) to remove the 4 screws
that hold the metal battery slide on the radio. These are at the outer
corners of the metal clip.
- Gently lift off the metal clip. Note that the two power wires are
on this so don't pull it too far off. Also note that there is a small
metal tab on this clip that is inserted in the battery release slide.
You will want to insert it back in the same hole when you replace the
metal clip.
- You will see a small RED wire loop as well as a small BLUE wire loop.
You can gently pull these up with some needle nose pliers. Cut the
loops and then cover the ends so they don't contact anything. My
method was to cut them not quite at the top, so one wire was a bit
longer than the other. I then slipped a small piece of heat shrink
tubing over the wires so the ends could not contact each other again.
This is probably adequate. I took a CLEAN soldering iron and used that
to shrink the tubing a bit just so it wouldn't move.
- Push the wire loops back into the radio. The metal battery clip will
push up against the circuit board running down the center of the radio
so you don't want the wire loops crossing over the circuit board.
- Replace the metal plate -- remember to stick the projection into the
small hole on the battery release slide.
- Replace the battery pack and reset the radio. You reset the radio by
holding the function key down and turning on the power. Note that
this clears all memories, so make the mod early -- this thing has
40 memory channels - a lot to reprogram.
I cut both jumpers. Documentation I have, as well as verbal instructions
was that the RED jumper opens up the out of band receive -- aircraft
and cellular, while the BLUE wire opens up the out of band transmit.
You certainly can't transmit in the aircraft or 800 band, I don't
know just what transmit limits are, don't have any reason to stray
outside of the ham band.

Note: I haven't tried or verified this, proceed at your own risk.
And do not transmit outside of legal bands! WA2ISE
