The only way to do that with vhf/uhf rigs would be using linked repeaters.
A possibility is Echolink. I currently don't see RF links near Radford or Petersburg, however It is possible for the two of you to use your PC's instead of radios. Of course you have to be licensed. You'll have to wait to get your calls as when you register you both have to be verified as licensed in order to use Echolink.
Another possibility that does require radios on both ends is IRLP. If there is a node near both locations then you're in business once you're licensed.
Yet another possibilty is getting radios with DMR capability. There is a DMR repeater in the Petersburg area; the closest to Radford appears to be in Wytheville. Whether it's reachable from Radford is another thing though.
Congrats to both of you for getting licensed!

I started looking up what repeaters are available to him in his area:
442.0750 +5 MHz D712 / D712 Pulaski, Peaks Knob Pulaski K4XE OPEN
147.0000 +0.6 MHz 107.2 / 107.2 Radford (independent) KB4RU OPEN ON-AIR
147.1800 +0.6 MHz 103.5 / 103.5 Radford, Cloyd's Mountain Pulaski N4NRV OPEN ON-AIR
146.7150 -0.6 MHz Blacksburg, Brush Mountain Montgomery W9KIC OPEN ON-AIR
444.6500 +5 MHz 107.2 Blacksburg, Brush Mountain Montgomery N4NRV OPEN ON-AIR
I programmed, using chirp, these into his Boafeng that he got for free for joining the local radio club after passing the exam.
I'm still new to all this, especially the repeaters, so not sure what he'll be able to do with these repeaters.
I'm guessing it depends on the power of the repeater but if he taps in to a repeater how far out will it carry his message?
