My listening preferences include talk radio, news, music, digital transmissions, and ham radio voice/data. Each person has different tastes when it comes to shortwave radios and I will try to generalize my list of must haves. but know there is some bias in my opinion. I am also interested in hearing about your opinions in the comments!
