FT-847 Windows Emulator for the FT-736R
This software will enable you
to use the FT-736R with Ham Radio Deluxe. This is offered with absolutely
no support other than what has been provided here. I have had many
requests for this software, but I can not spare the time for support. Three
other people have gotten this to work with the information below with no
problems.
This software was never meant
to be used outside of my house, so it is not polished. It can be seen in use at
http://www.youtube.com/watch?v=7H98FBQZJ_A.
The software can be
downloaded here.
There are the brief
instructions for making it work. These are included in the download as well.
You can use three serial
ports, or use a free Serial port emulator. I will show the serial port emulator
method here. First, download the emulator at http://www.eterlogic.com/Products.VSPE.html
Open the serial port emulator
and create a virtual port. This should be a port number that does not exist in
hardware. This will be what HRD uses to talk to. In this case below, I created
Com Port 7. It is referred to as a connector, and unlike real serial ports, two
devices can connect to it forming a virtual serial bridge.
Next, Open up my 847 Emulator
and you will get the screen below
HRD com port is the virtual
one you just set up
The 736 port is an actual
hardware port that exists on your computer and used to connect to the 736. See
RS-232 interfacing section below hardware details.
After this is set up, click
ok and you will see the following which are the values of data that are stored
from HRD and read back to HRD. These values are also used to communicate with
the 736. The commands are obviously different, so conversion occurs.
Now you are ready to open
HRD. My values are shown below. Your serial ports will
Probably be different. After
all is setup, connect and enjoy the emulator. After all of this, you can see
Why I don’t want to
release this.
RS-232 Interfacing
There seems to be some
confusion about the serial interfacing. Yaesu made an
interface that had a 25 pin serial connector and the appropriate DIN connector at
the other end. These are fairly uncommon these days. The 736 at the DIN
connector is expecting TTL levels, so yes inversion and level shifting is
required. Here is a schematic of the circuit I made a while back. I have two
DIN connectors on the output so that I can use it on older radios like the 736
and newer radios like the FT-817
