A level shifter is required for RS-232. I used a homebrew copy of the Icom OPC-478 cable. This link has a schematic looks like the one I used. I can't find the original link at the moment. Of course you need to change the connector to a 6 pin mini din. I use mine with several Icoms and the 8800. http://www.qsl.net/vk3jeg/opc-478.html

As far as I know, no additional equipment is required, at least with the USB cable. I don't think one is needed with the RS232, either, but I haven't used one.

Hi Aubrey So this cable has level converter built into it, or is a
level converter
not needed.

If you are wanting to use CHIRP with this radio, all you need
is the right
cable. No need to build anything unless you are into
tinkering with
electronics, as there are plenty of them on the market.
If you are lucky enough to still have an RS-232 port, here's
a serial
version:

If all you have is USB, here's one that should work quite
well:

Note that the above cables are a little pricey, and you can
find better
prices on eBay. But I picked this vendor in particular
because they use
the FTDI chipset in their USB cables, which usually just
works for people
as soon as the driver is installed. The cheap cables on eBay
often use
cloned chips that are based on Prolific chips, and Prolific
has
booby-trapped the later versions of the driver to fail with
these cloned
chips, so you have to jump through some hoops to get them to
work (i.e.
load older drivers and disable automatic driver updates). At
least this is
the case with Windows and USB. This isn't an issue with the
RS-232 version
(as there is no need for a USB-to-serial chip). It's also
not an issue
with USB on with Mac or Linux.

Greetings to the group
Just wondering if anyone can point me in the direction to an
interface I can build to communicate chirp with a Yaesu 8800 mobile radio.
