In connection with another program, I have done some superficial research into ADIF.
It seems as if there are two different standards out there: ADIF 1.0, on the hosenose site, and ADIF 2.1.5, on www.adif.org. Some ADIF exports seem to involve additional fields which are not in either standard. Looking at the filter editor in DX4WIN, I can't see any way to tell which fields are expected from a file being imported. Is there some way to view fieldnames and lengths, and to know where (QSO notes, for example) various data are imported into DX4WIN? 73, Pete N4ZR The World HF Contest Station Database was updated 12 January 2005 2868 contest stations at www.pvrc.org/WCSD/WCSDsearch.htm
