Well, yes, to spill the beans on this: it was when I was reviewing the filter gains on my K3 the other day that this came up. I built my K3 with the stock 2.7khz 5 pole filter in FL1 and an 8 pole 400hz in FL2 - however, to even out FL1 and FL2 requires the gain to be nearly maxed out for FL2 (8 db gain, IIRC). My K3S, however, has 8 pole 2.8khz and 400hz in goth FL1 and 2, respectively. But they're almost dead even in terms of attenuation with FL2 set at only 2 db gain.
So that led me to wonder if the 5 pole in my K3 had less attenuation in general, accounting for the difference. Just a curiosity for me. 73, LS W5QD -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-5-pole-vs-8-pole-filters-attenuation-in-the-passband-tp7614635p7614639.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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 Message delivered to [email protected]
