The Import/Export facility enables you to exchange memory information between the following radios by using .CSV format memory definition files. You will also need to use the appropriate FTBxxx software for the target radio.

  • FT-817, FT-847, FT-857, FT-897 (including ND and D models), FT-1802, FT-1807, FT-1900, FT-2800, FT-2900, FT-7800, FT-7900, FT-8800, FT-8900, FT1D, FT2D, FT-60, FT-250, FT-270, FTM-100D, FTM-350, FTM-3200D, VR-5000, VX-3, VX-8, VX-110, VX-150, VX-120, VX-170, VX-177
  • VX-2, VX-5, VX-6, VX-7 – using the Commander range of software by Jim Mitchell, KC8UNJ

Memory definitions can also be imported from TravelPlus for Repeaters using .TPE files, and from ButelSoftware’s ARC250.

The program runs on a standard PC that has an available COM port for connection to the transceiver and the COM port must be one with an FTDI USB chip.  It has been developed and tested on Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 10.

It will not run on Windows 8 RT version which does not support desktop applications. The minimum screen resolution is 800 x 600 but 1024 x 768 and above is recommended.

See the Links page for sources of cables and the Help file for DIY information.

Connection to the radio

Ready-made Cables

The radio is connected to the computer using a programming cable. The Links page of the website lists sources of ready-made cables that can be ordered over the Internet.

The Yaesu data cable is the CT-142 which has an 8-pin mini-din at one end to connect to the radio and a 9-pin DB9 at the PC end. There is also the CT-140 which has an extra lead for connecting a TNC. For programming the radio these cables must use a USB/serial converter that contains an FTDI USB chip; Prolific USB chips do not work at the non-standard cloning baud rate of 48000 baud.

DIY information

The radio uses an unusual cloning baud rate of 48000 baud. The built-in serial port of the author’s PC will NOT operate at that speed. During beta testing it was found that USB/serial adapters which are based on the Prolific chip do NOT work at that speed. Other makes of USB chip may also have problems. The ONLY USB/serial adapters the author has found that work are those using FTDI USB chips.

If anyone finds another make of USB chip that works then please contact the author to get this section updated.

The radio uses standard RS232 serial communications NOT TTL as do many other Yaesu radios. Here is a snapshot of receiving data from the FTM-350 – note that the polarity is Plus and Minus.

In the back of the APRS manual on page 35 there is a CT-142 cable diagram showing the pinout of the 8-pin mini-din on the radio and a 9-pin d-sub serial connector to the computer’s serial port or a USB/serial adapter. Note that the diagram shows the connecting pins of the connectors, not the cable ends.

No level conversion circuit is required – this is a simple wire-to-wire cable connection. If you already have a FTDI based USB/serial adapter then this is a cheap and easy way to get connected.

Warning: At the bottom of page 35 of early APRS manuals is a diagram of the data socket on the radio. In the author’s manual the numbering of the pins is wrong:

the pin labelled as 1 should be 4;

the pin labelled as 2 should be 1;

the pin labelled as 4 should be 2.

The revised manual issued with the release of firmware V1.2 has been corrected.

This is the correct pinout of the Data socket on the FTM-350


I am Bob Freeth, a retired radio ham G4HFQ and in my late 70s. Over the past 20 years I have written numerous programs that are of interest to radio hams. Most of the programs are for managing the memories and settings of Yaesu radios. I have ceased trading and look forward to a peaceful retirement!

24 October 2020 – Simplifying my committments

In the middle of October unexpected events beyond my control coupled with a continuing gradual degradation of my health have caused me to re-evaluate whether it is sensible for me to continue selling software over the internet.

I have decided to simplify my committments and cease trading. This does not mean that I will no longer provide any support for users of my software – that will continue to the best of my ability.

Over the next few months I will be working on updating the online versions of program help files and other items but the downloadable install programs will remain in place for those who need them when changing or re-building their computers.

15 December 2020 – Free of charge registration details

All of my software is now free of charge and registration details for each program are contained in Free_registration_details

Only should you wish to do so I will be pleased if you would make a small donation to any charity of your choice. If you can’t decide which one is right for you there are many National Red Cross and Red Crescent Societies around the world; I am sure you will find one operating in your own country. Another suggestion is to donate to a food bank to directly help those in hard times.

Also welcome would be additional websites to host the software downloads and list of program registrations. It would be a shame if I suddenly dropped off my perch and this website disappeared. Please get in touch if you could provide such a service.

73, Bob – G4HFQ
