FT-950 Software Updates

John: The mods you are asking about on the Yaesu site, are Firmware updates. These will change some functions of the DSP and control operation for the FT-950.
There are two specific downloads....one is DSP update....the other is main CPU updates.
They are both contained in the download from Yaesu. When you open the file after download to your computer there will be an instruction sheet(read me file) that gives you information as to how to transfer the updates to your FT-950...they must be done as stated or they will not transfer, but if you make a mistake it will not disable the radio just will not load.
You need only update the latest version of both files as they contain all previous updates.
I finished the latest ones a couple weeks back...WOW DSP I think is much improved, plus the RX noise threshold is much lower making the receiver much hotter. This latest also improves the 2 noise blankers software making them much more effective.

The FT-950 I have is about 2 years old D8XXX series(28th production run)...these updates work on the first of the 40+ production runs...
Yaesu has done a great job to keep improving the firmware of these great radios.
She'll be a completely new rig if that is one of the first production runs they made and she has never been updated.

VERY IMPORTANT NOTICE:
This update procedure is for the FT-950 MAIN and EDSP software. The MAIN software is for all lot
numbers. The EDSP software is different. Please verify the version of the radio by the serial number.


The third and fourth digits indicate the lot number, example xx
42xxxx. For lots 01 thru 42 proceed

with MAIN and EDSP software update. For lots xx


43xxxx and above install the MAIN only, do not

install the EDSP software.
You may also verify the current EDSP level of your radio (The software versions can be displayed on
the radio, see the below instructions). If the first digit of the number is 2 (example


20.45 1.13) Do not

install this update EDSP software, It is not compatible with EDSP level 2 radios.
Radios with lot numbers 43 and above, cannot operate with EDSP Ver. 11.54 software.


At this

time (7/12/2010) there are no updates for EDSP level 2 radios.
PEP950
This procedure is used to update Main CPU Ver. 0115 and EDSP Ver. 11.54 the
flash programming for the FT-950 Transceivers.
We recommend installing the Flash Programming Software on a PC computer with Windows 2000,
XP or Vista Operating System; and use the serial cable RS


-232C, DB9F to DB9F straight cable.

NOTE:


There are many USB adapters available; however some may not function with this software.

We recommend using the latest USB adapter driver software when available.
The software versions can be displayed on the radio
While holding the three buttons [GEN]


[50][ENT] turn the radio on. The software version will be

displayed in the VFO-A window for 5 seconds then the radio will start up in normal operation.
See below:


Example EDSP V11.53 and MAIN V1.12 software version.

*If you already have


EDSP V11.54 or V20.45, and MAIN V0115 software versions, it is not necessary to update

the FT


-950 again.

The software updates will work with all versions (AF, AS, EU, NA, OC, SA or all Countries) of the FT-950.
Main CPU:
Software version


01XX


(This image & version is for

longer be heard when pressing any buttons, after the procedure is exited.
Ver. 11.54 EDSP implements improvements (4/5/10)
(This update Ver. 11.54 EDSP is only for the FT-950 lot numbers 01 to 42)

    ...ebay. I will also file a case/complaint with my local sheriff's dept tomorrow. I'm good friends with the sheriff so I hope you'll be able to help me in this process. This guy has been a criminal (at least on eBay) for over11 years. I see the first post on here regarding his criminal behavior was in 2011. Has anybody else filed a complaint against this low-life scam artist? Any suggestions/help on getting my $$$ back would be greatly appreciated. Thanks!
