In the meantime the docs have been updated so that carriertracking is described to be mixing the input with the recovered carrier. Yet, the code is still unchanged (e.g. carriertracking and refout still do exactly the same). This took me several hours to figure out. Attached is a trivial patch to fix that. -- Henryk Plötz Grüße aus Berlin ~~~~~~~ Un-CDs, nein danke! http://www.heise.de/ct/cd-register/ ~~~~~~~ ~ Help Microsoft fight software piracy: Give Linux to a friend today! ~
