Yaesu ft-2900r frequency modification mars mod

So I was browsing the internet and learned of a really simple modification to the yeasu ft2900r mobile 2m transceiver. The radio comes stock with the abilty to receive from 136-174 MHz but will only transmit on the 2m ham band. Performing this mod, according to what I read, unlocks it for tx on I believe the entire rx range.. I was wondering if anyone on here ever heard of or performed this mod.. and yes I have legal reasons to do so..
