Past Actvities

In the period between the 10th April, 1967 and the 25th May, 2007 I held the call VK2ZTO (I no longer hold that call).   Under the VK2ZTO callsign I engaged in a number activities, including:

  • invention of IFK (Incremental Frequency Keying - the basis of Jason & DominoEX)
  • experiments with narrowband modes (FDK and AFK)
  • authoring VFSKCW software
  • VLF (8975Hz) experiments
  • HiFer (13Mhz ISM band) experiments (including a HF version of FDK called Wandjina)

I maintain an interest in the FDK method - see "Present Activities" below...

Future Activities

Before inventing the IFK method I came up with concept of FDK (Frequency Difference Keying).

FDK will be the initial focus of this website - especially for HF frequencies (Wandjina).

Small Joke Alert:   "An FSK called Wandjina..."
