I would have no use for a 750 Hz filter. 99% of the time I use SSB bandwidth on emty CW bands, or less than 500 Hz BW.
I have my filters set so the 500 Hz roofing kicks in at 600 Hz BW, my 250 roofing in at 350. This is in an attempt to soften the big 50 Hz selectivity steps when using narrow filters. The only "selectivity thing" I would like to change is the huge percentage of step change at narrow selectivity. I find the steps much too abrupt, especially when the DSP changes at the same time the roofing filter does in a step. :-) The 50 Hz steps really annoy me at narrow CW selectivities. ______________________________________________________________ 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
