ESSB Audio Techniques Page
This FT-2000 Page contains all of the previous FT2000 Firmware (FW)
updates available for download. These will allow you to roll-back the radio's Main and EDSP FW to any earlier date for
testing and trouble shooting.
The simple answer is why not if you're having a problem. If you detect a problem when updating to the latest version, this section will allow you to select an earlier version for both EDSP and MAIN to test what happens.
I've saved all of the FW updates after I purchased the radio. It's a late 2007 version, which had V1.38 Main FW and 10.29 EDSP loaded. As I have updated the radio (current is 11.54 and V1.56), I've saved the older files . . . just in case!
FW Download Procedure
Download the desired FW update shown in the table below, unzip it and follow the instructions contained in the ZIP file. In some cases, there are multiple zip files that need to be unzipped. The files here have been directly d/l from Yaesu and preserved in their original format and are exactly as Yaesu released them. I've added the separate PDF how-to-instructions into the ZIP bundle so each is a complete package. Yaesu's instructions are based on the use of the "CT119" cable.
I'm NOT responsible for any problems that may occur. Take your time and you will have no trouble if you follow the instructions exactly as written. To update my radio, I've used the special 8 pin mini-din plug along along with a standard RS-232 modem cable with zero problems. Details here
