Dick,
You probably mean the latest version of Spectran which has all of the usual
waterfall stuff, plus a very easy to use CW filter. The frequency display
shows the incoming signal, and also the edges of the filter which can be
adjusted simply by left or right clicking the mouse. You can easily separate
the wanted and interfering signal this way.
Download it from http://www.qsl.net/padan/spectran.html

Hi Dick, hi Mike,
Spectran is ok if u are contented with one filter.
I do use "SbFFT by KW5Q" when dxing on sw or looking for spurious. with SbFFT u
can switch up to six individuel/independent filters.
I don´t know any more where I did get that program. its amateur freeware
running on DOS level. windows or other Betriebssysteme should be off.
guess Ko/NL9222 knows where u can get the software.
if not, let me know. I could compress it down to a 1,8MB ZIP and e-mail it
direct.
regards
Uwe/dj8wx
