Amateur Data Interchange Format (ADIF) was conceived by Dennis Hevener WN4AZY. He contacted Ray Ortgiesen IV WF1B with the idea, and together they developed the ADIF protocol for standardized data interchange between ham radio software programs.   It was debuted by Ray WF1B at the 1996 Dayton Hamvention and quickly gained acceptance among ham software developers.

Dennis WN4AZY is the author of the LOGic amateur radio software program and co-founder of Personal Database Applications Inc. Ray WF1B wrote the WF1B RTTY program.

Today, ADIF is an industry standard in amateur radio software, and has taken on a life of its own. For more information on ADIF specifications, developers may go to ADIF.org.
