N7NBB is correct, you have to be a licensed tech to work on commercial gear, including alignments. However, there's nothing wrong with getting the crystals from ICM (which is my preferred source) and delivering them along with the radio to a service shop for installation and alignment. You will save a little money doing it this way rather than having the shop order the crystals for you and charge for that service. It's worth the money, when you get the radio back you know it will be on freq, and the TX/RX aligned to spec.
