i need to get an amateur radio license...

radio is cool also quite useful

@crashglasshouses haven't looked into it much. the most useful seeming thing with short wave radio and such is the ability to send long distance messages with minimal infrastructure, does SDR also that?

@binarycat yes, with the right equipment, you can send as well as receive. there's a lot of different SDR equipment, with the simplest sometimes costing as little as $20 for a kit, which is a USB dongle meant for decoding DVB, and an antenna to attach to it. then you can use whatever software you like to interact with the receiver.
