that's my first email on this mailling list , and nearly my first email on a mailling list :) , i hope i will not do mistakes . 

My radio is a Baofeng UV-6R  

I've recently installed CHIRP on a WIN7 Virtual-machine , and on my Mac . 

In both system i can read and right  in Memory tab ( frequency , channel and so on) , no problem. 

but i see a "Setting tab" , this one is completely blank .

i've checked on internet and in all mods ( ie. for UV-5xx) guys are using setting to change freq. range or other stuff .. 

please find in attache  a screenshot 

any advice? 

Thanks in advance 

Tom
