Have a YAESU mobile rig but no programming cable?
Did you know that your
mobile programming cable and
handheld programming cable are exactly the same except for the connector
that mates with the radio? Read on!
Make a tiny conversion kit to use your YAESU amateur
HT programming cable with your YAESU amateur mobile rig!

Parts you will need:
1. Your existing
YAESU programming cable from
your handheld radio.
2. Baseboard modular telephone jack with at
least four conductors (two lines, RJ-11).
3. A four-conductor
or six-conductor telephone cord, any length
4. A three-conductor (stereo) 1/8" (3.5mm)
headphone jack (Radio Shack 274-249).
A picture of the electronics:
Here is a shot of the YAESU programming cable for
handheld radios with the cover removed. The cable that is soldered
to the PC board looks as if it was originally manufactured for audio
use. The white wire is connected to the middle conductor of the
1/8" headphone jack. The black wire is connected to the base
conductor of the jack. The red wire is connected to the tip of the
jack, but was cut off during manufacture as it's not used. This
assembly is exactly the same as the amateur mobile radio programming
cable except that the stereo 1/8" plug on the end of the cord is
replaced with an RJ-11 connector. You could cut off the 1/8"
plug and replace it with an RJ-11 connector, but then you wouldn't be
able to program your handheld radios when you wanted to. Duh!
Solder some wires:
Solder a yellow wire and red wire, both about 5 inches,
to your new 1/8" female headphone jack. The red wire will
correspond to the base conductor and yellow wire will correspond to the
center conductor of your programmer's male headphone jack.
Hook up the wires:
|Strip and connect the red wire to the red terminal and
yellow wire to the yellow terminal inside the baseboard telephone jack.
Drill a hole:
Use a 1/4" drill bit to make a
mounting hole for your stereo headphone jack. Be sure that the
jack will fit properly underneath the cover when it's assembled before
drilling the hole. Protect your table by placing something
invaluable between it and the drill bit. See example for what's
Mount the jack in the jack:
Poke the headphone jack through the hole you just
drilled and secure it by screwing and tightening the ring down.
Before snapping the cover on, check for wires or contacts that may short
or be pinched. Fix any potential problems.
Snap the cover on:
|Get the idea?
Try out your new creation:
Hook up your programming cable as you normally would to
your computer. Use your new converter to go from the stereo jack
to RJ-45. Use a length of two-line four-conductor telephone cable
(two conductor will not work) to
go between the converter and your YAESU mobile radio. Load your
mobile programming software and program away! (You may also use a
six-conductor cable successfully)

SOFTWARE UPDATE: I was told by YAESU that the FT-90
software was "on it's way -- in development," but so far - nothing.
I then decided to contact RT Systems, the people who have been writing the
software for YAESU. It turns out that RT Systems wrote the software for
the FT-90, but YAESU decided NOT to buy it from RT Systems this time. RT
Systems has been the software supplier for previous YAESU radios. I
believe that YAESU will get the software from some other company this time or
will perhaps write it themselves to make a buck or two.
Meanwhile, RT Systems is selling the software that YAESU did not buy and is not
supporting. It's $39 plus $5 or so for shipping.
You can order the FT-90 programming software from:
RT Systems, Inc.

Or, you can wait to buy the official YAESU FT-90 software --
if it ever comes out. I am perfectly happy with the RT Systems version
As you probably noticed on my web page above, you saw a link
to the SH CopyStar page. It is a neat shareware program that allows you to
COPY the copy-protected programming kit installation disk on a sector-by-sector
basis to another floppy disk for use as a "backup". As well, you
can use the IMPORT/EXPORT functions to transfer the image of the installation
disk to an empty folder on your hard drive for backup purposes and even send the
image folder over the internet to a friend who would also be using SH
The image then allows you to create a new floppy at your convenience from the
data stored on your hard drive or sent via internet.

SH CopyStar Tips:
- It wouldn't hurt to make sure that your setup options
are set optimally. Click "Setup > Options >" to
make sure that "Verify" and "Format Always"
are both checked. Also, be sure that "Disk Authenticity - Modify"
on the same page is unchecked.
- When you first start SH CopyStar and receive "FORMAT
WILL NOT FIT ON THIS DISK" when you click "Read," you
will not be able to continue. To avoid this message, close SH CopyStar,
use Windows Explorer or My Computer to view the contents of your source in the
floppy drive (press F5 to refresh if necessary). Simply viewing the
contents of the drive in this manner is enough to make Windows realize the
actual format of the current disk in the drive. Re-start SH CopyStar and
click "Read" one more time to successfully read the disk in the
- If you EXPORT the disk image, you should
realize that disk format size is NOT included in this image. When you EXPORT
an original disk, make note of the disk format size. Then, when you or a
friend later IMPORT the disk image from a hard drive or internet, you
must manually specify the format that the source disk was in before creating a
new duplicate floppy. After you IMPORT an image and before WRITING
the duplicate floppy, click "Image > Change Format..." and
select the format that the original source disk was written.
