Today, thousands of professional digital data stations are active on tenthousands of HF frequencies. Cutting-edge technology is used for automatic data transmission over worldwide aeronautical, company, diplomatic, military, maritime, and NGO e-mail networks. Receiving and decoding these stations is far more fascinating than listening to broadcast radio stations. We've been leading in this field for 47 years! Below you will find a few - very recent! - examples of what can be really monitored today. Several hundred screenshots can be found here. Read our Perseus User Test here!
