72.080 Is not one of our hobby band channels and is illegal to use and became so long ago in 1991. Since the receiver has that crystal in it its likely the Rx is also an old wide band unit, is it Am or Fm ? if its Fm its probably not a dual conversion rx. probably should have been round filed years ago, You can check at the futaba website.

The Flash five is an older entry level computer Tx and legal to use as long as someone has not gone and switched crystals, you can only do that in receivers. That Tx untill fairly recently would have sold for perhaps twentyfive bucks around here but not anymore. Even old entry computer radios have become almost worthless.

The bottom line is at this time of change there is a flood of old crap being sold everywhere some acceptable and some even illegal and unless you are knowlegeable most people get burnt when trying to piecemeal a system together. get with your club or mentor before buying anything used. Heck for that matter anything new also!
