 From the information I have, undocumented peek and poke cat commands 
still works but yeasu blocked the possibility to write on the 
configuration byte (at address 4 and 5) on newer radio to avoid 
"softjump" tampering.

If you are a brave you can try to write on the label of one of the 
memories to see if the poke command still work, I suggest you don't 
write on current memory channel as seems yeasu radio don't like this.
You can calculate the address using info on 
http://www.webalice.it/famiglia.pagni/default.html (in the hope they are 
right).

BTW I widebanded my 857 with softjump lots of years ago.
