The rdft routines are not integrated into scamp, they are "external exe's". Same trick is used by mixw, gpl-code is moved to an "external" library. While this seems to be legal in the scamp case, the mixw case could be different. To use GPL code in a library (.lib or .dll) the code must be released under lgpl (library gpl) i think. My personal thougths: It is very impolite to push a freeware developer to release his source with legal threats. The developper will get angry and stop working (for free) for the ham-community. This is an absolute NO-GO !
