No you can't. 72 MHz radios are designated by the FCC for airborne use only. 75 MHz radios are designated for surface use.. And while it is possible to change a 72 MHz radio into a 75 MHz radio it must be done by a licensed person and it will dost more than it is worth. As far as aircraft use you may also have an issue with channel separation. That is right around the time narrow band radios were being required and the older radios are now no longer allowed. Check what channel it is on. If it is an odd number it is fine. If even there is a way to tell if is narrow band but I don't recall what that is. A local hobby shop with some older sales people, or a club that isn't all snobby about 2.4GHz can help you. And don't believe someone if they tell you no 72 MHz radios can be used. That's bull. The older wideband can't but the narrowband can. It might even say on the radio. Or someone else here might remember if the VG6R is narrowband.
