[linrad] RE: Bamboozled by bandwidth
Just getting going here and have read all the QEX articles with great
interest. I am bewitched, bothered and bewildered over the question
of bandwidth requirements.
It would be useful to see a display of activity taking place in the
frequency spectrum of interest for example my operation is almost
exclusively in the low 25 kHz of the HF CW bands. When in QSO I only
need a 100 Hz or so and I note that Leif states that large
bandwidths are primarily required for noise reduction functions but
that increases the problems of dealing with large in-band signals.
Given a high performance HF radio (mine is a Ten-tec Omni pro) with
100 Hz Xtal filtering, linrad DSP and a 16 bit sound card what's to
be gained by more elaborate hardware measures that increase bandwidth
? What am I missing ?
