I'm really intrigued by digital modes. Stuff like JS8Call seems really cool, and I want to get into it.

I don't have any HF equipment. SSB isn't very interesting to me, so I was thinking of getting a digital-only transceiver and saving some money. I think it would be cool to take a small QRP box with a laptop or raspi, and do digital mode Pota with it.

I've seen the QDX which looks exactly like what I want and seems to get good reviews. Any others that I should be aware of?
