[Kenwood] TS-950SDX EPROM discontinued

Fri Sep 4 10:48:19 EDT 2009

If I recall correctly, the 850 has a firmware eprom as well, but I'm not aware of any issues or updates to the original firmware version.  The 950SDX clearly had some issues with the earlier version, thus the need for Kenwood to release an update (and corresponding service bulletin). 

If anyone is aware of more than one version of firmware in the TS850S, please let us know. 

I haven't seen a DSP-100 in years. Once again, I don't recall any past discussions about firmware revisions to the DSP-100.

Does the TS-850 have the same scenario that we 850 users should worry about? Also, what about the DSP-100? 

Thanks,

Thanks to Mike WZ5Q, who graciously pulled the original eprom from his TS-950SDX, we now have an image (BIN) file of the original eprom.   

If anyone is interested in updating their 950SDX's firmware to the latest (last) version , I have a few newly burned (aka programmed) firmware chips for the TS-950SDX at a cost of $25 including shipping via USPS first class mail.

It is accessible just fine.  If it is an eprom, I can read it (and therefore clone it).  Since I am only interested in cloning it, I do not need the original source code or compiling utilities to decipher any embedded info. 

I've successfully done this on other radios in the past.

Same Difference. 
You know what I meant. 
The Data is probably not accessible.
