Sound Clips of Various Propagation Modes

This is a collection of sound clips of various VHF and UHF signal modes.
Except where noted otherwise, all recordings were made in the Blue Mountains, west of Sydney (VK2).

Note that the files may take up to 1.7 times the run time just to load
- I have edited them down as much as possible, so please be patient.

• Normal tropospheric propagation
  • VK1BG on 144MHz ssb, November 2000 (12s, 27kB)
    
• Aircraft Enhancement
