Is there a way to extract only the radio from a Kaiser?

[jubanet]

I have here two devices, one (the original) is:

rom 1.88.514.1 PTB
data 02/01/08
radio 1.27.15.21
proto 22.51.88.13H

the other I changed everything :)
Now, for warranty purposes I need to change it to the original state.

I just dumped the rom from the first one, but don´t know how to get the radio...

any help is welcome!
