Old Argument , Rehashed I seriously doubt that a marine HF radio can be coaxed onto any Amateur band with out some very illegal tampering, rendering it illegal to go back to operating on the marine channels. Sure, if you mod a commercial radio you CAN use it as a Ham radio but not for it's original purpose again. I am sure the "type acceptance certification" would be void if you start modifying it. I know it is not legal to operate an Amateur band radio on any commercial, marine, business, public safety or Aero freq !!
