Their explanation about how the PEP modem had to retrain at various noise levels doesn't quite make sense to me unless the modem had to readjust which frequencies it was using. In other words, we were probably seeing a graph of changes in the frequency response curve of their noise generator! -- David Keaton dmk%dmk3b1@uunet.uu.net uunet!dmk3b1!dmk
