What receiver were using Jim? I don't think we could really be proud of the
equipment we all are using as hams. When the average third order intercept
point of the most top line radios hovers around +10 to +15 dbm judging
signals in Europe under contest conditions is a big ask. Military receivers
of the late 1980s had intercept points of around +30dbm, ham manufacturers
certainly have a long way to go. Dr Ulrich Rhode has covered all these
issues in the Ham press back in the days of Ham radio magazine, and also
quite recently in QST, QEX and Communications quartely. More pressure has
to be applied to ham manufacturers to provide excellent RF reveiver
performance and not concentrate so much on bells and whistles.
