You'll need a radio that can pick up 3MHz-30MHz (with single sideband) if you want to listen to global AM plus long range ham operators. [Here is a decent list for receivers. ](https://www.savenetradio.org/best-shortwave-radios/) You can transmit in these frequencies as well, but the gear & antennas can be pricey. [If you have the budget, an Icom with waterfall display is a choice selection.](https://www.dxengineering.com/parts/ico-ic-7300) Baofengs are (generally) for local comms (unless you're using repeaters). There are good arguments for owning a range of radios for different purposes.
