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



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
