Yes! I used the software to change my 272 to a 270 (via the model pull down).
Now I have the 128 channel/zone combo. As far as I can tell, all other functions work as advertised. No special hacking needed. Don't worry about a firmware update if the radio operates normally.
With all the newer portables I have, my TK-272G (I mean TK-270G) has the size and performance that beats out the others. It's my main go-to for just general snooping around.
