OT: RE: out of specification operation with Si4721 for use on 4 Meters #parts

I found this data sheet while reading up on the Silicon Labs SI4721 FM Broadcast transceiver chip, I have to ask if it can be tuned outside of it's specified range into maybe the 4 Meters band or maybe even up into the 2 meters band as well. the data sheet indicates that the stereo pilot and inputs can be disabled along with an easy way to specify the deviation of the transmitter. so far this looks like a nice little part to build a Handie Talkie around for fun. https://cdn-shop.adafruit.com/datasheets/SiLabs+Programming+guide+AN332.pdf
