Ah but, under noisy band conditions the bandwidth of the listening receiver is most probably set to some value much less than 2.4 kHz. So I would question whether a wider filter in the transmitter does in fact result in improved intelligibility under these conditions.
FWIW I find that a 2.1 kHz filter in the transmitter, with the carrier placed so that the audio frequencies from 300 Hz downwards are attenuated, works well under noisy conditions without sounding like a parrot. 73, Geoff GM4ESD Ron D'Eau Claire wrote on Friday, October 16, 2009 at 11:26 PM: > The improved intelligibility of the wider filter comes from the better > high > frequency response. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
