That is THE primary reason I want to upgrade my license and build or buy an HF radio.
DXing is fun. No doubt about it. Finding that new entity in the sea of signals, making your call, and seeing your call come back from some far away land is exciting. My latest new one is Scotland on PSK. Added Brazil just a couple days before.
From an backup comm point I see PSK being very useful. It doesn't take much power and if you can get some sort of 20m antenna up you'll be nearly guaranteed making contact with somebody. The negative is that some sort of computer is required for the digital modes. Thinking a netbook running WinXP as the OS might do the trick. There is an app for the IPhone for PSK now.
Upgrading to General really opens up what you can do. In the meantime build a 10m antenna and get your digital rig up and running. Yes, you can do that as a Tech. Tech privileges include data and RTTY from 28.0 to 28.3, the same as everybody else. And don't forget the Tech has SSB phone privileges from 28.3 to 28.5 which just happens where a lot of the activity is anyway.
