This is copied verbatim from the mod sheet I received with my rig...

In side the rig, it really did not look quite like that ...    more like this:

...  12 (|)  (|) 11
           (|) 13
      16 (|)  (|) 15

In addition to the published receive expansion, it also receives 800-950 MHz...
trunking radio, cell phone (I would *never* listen to that), 33cm ham band...

Have fun!

This is a compilation of modification information I received in response to
my posted query and the info faxed to me by Yaesu.

There are at least 2 board layouts out there.
Note that while the jumper pad numbers have not changed, the board positions
of the pads have.

    Pad 15 now a vertical pad with a tiny
    "zero ohm" resistor.


My rig got confused after this mod and it was neccessary to reset the
CPU. (The 70cm repeater offset register got fouled up and though it could
be incremented and decremented by the normal 50khz,
it went 0.01mhz, 0.06, 0.11, ect. instead of 0.00mhz, 0.05, 0.10, ect.).

Reset command: turn radio on while holding "MR" and "FM"
(Damn, memories erased again!)

If anyone figures out how to receive higher freqs, say up to 800-950mhz,
(so I can listen to the 900mhz ham band of course),  8-)
please let me know!

Thanks

You are correct, I should have said REMOVE jumper 13 to get rx 110-180,
300-500, and 800-950.  Also tx 130-180 and 400-472.

However the mod sheet DOES say jump pad 12 for tone burst.

I will gladly send a copy of it to anyone who sends me a sase.

As you all know the mod for the Yeasu FT-530 is to remove the jumper #13. The
next step is very important and a few mod plans don't mention. The CPU needs
to be reset by holding the UP and DOWN keys while turning the radio on. Before
you do the reset, remember to remove all power sources to this radio and wait
for the rig to completely discharged prior to the reset. If the rig is not
totally discharged, the mod will not work. Good luck
