But this is not insurmountable and many people are now working on new ways of creating suitable sampling frames. International shortwave broadcasting is no longer so unusual in its relationship to audience, feedback, etc. Sometimes this is because their audiences are also scattered and small, just like shortwave audiences tend to be.

This can be used to generate addresses on a database that can be used over time to learn about those who write, track changes in what they like and listen to, learn about who they are and invite regular feedback and other useful knowledge. The drawbacks are that no quantitative assessment of impact can be made. This is a self-selected sample and may not be representative of the audience as a whole. Those who write are different from those who listen. However, we know from research that responses from listeners can give an accurate picture of reception conditions.
