Then it's better to use offset from the QSY information and not the  
inbuilt data in the radio. It's better as we can now have one standard  
and that is to include the correct offset and remove the possibility  
that we have to assume either one.

When i have modified my TM-D710E to an TM-D710A it's "useless" in  
No(r)way regarding some "standard" settings. Why modify it? To be able  
to use functions that are legal to use that previous has been blocked  
in the E model.

After i found out on how to modify the radio to get SkyCommand it's  
possible with a firmware upgrade and i wish that Wireless also was  
enabled via firmware.

Then i would say that we should drop the "standard offset" and include  
the offset in the QSY information as this is always going to work  
regardless country and bandplans etc. Let the owner of the QSY  
information dictate what the receiver should set. This is going to  
give less errors as it's "only" human generated objects that could  
mess things up and not wrong settings in the radio.

The "range" part could have been removed as this is not science and if  
you receive the object you most likely are going to be able to use the  
repeater.
