Hello, Can somebody explain to me why the "audio" noise increase when i select a lower BW XTAL filter? For example going from 1k8 to 400Hz.
As i use often BPSK31, the "blue" background of my waterfall (without signal present) go into the "yellow" color; (using Digipan with "standard" waterfall colors). I was expecting a "constant" level or a noise reduction, but not an increase. Is it a Filter gain setting to modify in my K3? Mny tnx in advance! 73 QRO de Rudolf, HB9ARI PS At 66 yo, it's not to late to learn something! ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
