    One of the coolest things in my opinion about radio is the ability to skip off the upper atmosphere and bounce a signal back down halfway across the globe. You can also bounce a signal off the moon.

      2m doesn’t bounce off the atmosphere. You really need 10m for that. 6m in the mist perfect ideal scenarios but it’s still very rare (and in this scenario you aren’t gonna know when). EME (the moon stuff) is also pretty tricky and requires a lot of power because of how messed up the signals get in the process.
