Reliably talking 100 miles via radio is highly unlikely, unless one of the radios is on a mountain, and both radios are using directional antennas. You would need high power- 75-100 watt radios and need to be able to use the remote radio from an elevated vantage point.
It can be done with repeater systems, but systems go down. Reliable radio-radio comms will be relatively short range, unless shortwave is used. This is where the hams come in.
