Yaesu Digital Mode and CAT Control Interfaces

Yaesu CAT control and Digital mode interfaces allowing you to use Digimode Software such as Ham Radio Deluxe, FLDigi, WSJT-X to operate PSK31, FT-8, JT9, JT-65, Echolink and many other AFSK modes.

We offer a lot of interface versions and always get asked which interface is best for my set-up. This very much depends on your PC, radio, budget and the performance you are looking for.

Some of our interfaces use your PCs internal sound card. These rely on your PC having separate 3.5mm Line Out and Mic In jacks. Some of our interfaces give you a separate external USB Sound card which frees up your PCs internal card for normal Windows duties. Some interfaces are galvanically isolated and are best chosen if you are worried about grounding. Some of our budget interfaces are not galvanically isolated.

Only you know which one suits your particular needs based on your particular shack set-up, what your budget is and what features you need.

ALL of our Digimode interfaces are suitable for FT8, JT65, PSK, Echolink and the other myriad of Digital Modes you can play with.

The table below summarises the main features of our digimode interfaces to help you choose.

* The FT-990 requires firmware V1.3 and the FT-1000/FT-1000D require Firmware V6.0. Please contact me if you need details of how to check this. I sell V6.0 Upgrade Eproms for the FT-1000/1000D.

The supply of one programmed Prom with Yaesu Version 6.0 firmware for the FT-1000 and FT-1000D. Full installation instructions will be provided. All you need are a few basic tools and the confidence to carry out this simple installation on the FT-1000 or FT-1000D. You will need remove the original Rom from it's socket on the the control unit and replace it with the supplied Eprom. The installation can easily be carried out in less than half an hour.

If you intend to control your FT-1000 or FT-1000D from your PC via the CAT (Computer Aided Transceiver) interface, you are advised to have Firmware 6.0 installed. Although earlier versions of the firmware claimed to be CAT compliant with details published in the transceiver user manual, the data format was found to give problems with many CAT control applications. The problems presented themselves as slow control between the radio and PC or no connection at all. The issue seems to be related to the size of the data block returned by the radio being too long causing the CAT control applications to "time out" or lose synchronisation with the transceiver.

Yaesu recognised this issue and released firmware 6.0 to fix the problem. While the FT-1000 and FT-1000D transceivers were supported by Yaesu, a firmware update programme was made available via Yeasu Dealers. This involved returning the transceiver for installation of the new Rom. However, since the Yaesu support for the transceivers has long been discontinued, the Dealer firmware update option was withdrawn.

This "after-market" firmware update will allow you to bring your FT-1000D up to v6.0 which is the very latest Rom version making the transceiver fully CAT compliant with the many CAT control applications available.

How do I know which firmware is currently installed on my FT-1000D?
This is known as the Las Vegas test. Turn off the transceiver and whilst holding the 1+3 keypad buttons, turn the radio back on. The display will reveal the firmware revision. If your FT-1000 returns "Yaesu 6.00" in the display, you already have the latest firmware version and you do not need to buy this Eprom. Transceivers with firmware revisions lower than 6.00 will benefit from the upgrade if you want to make use of the CAT functionality.
