IMHO - NO. The 2.7 or 2.8 is used as your "normal" phone filter. The difference is the slope of the skirts being steeper on the 8 pole, BUT, when you NEED to rid yourself of close a close in strong station, you will be far better off to have added a 2.1 or 1.8 filter rather than trying to "get by" with the 2.7 OR the 2.8 filters.
I see I am bucking the vote here but for nearly the same money spent on adding my 1.8, I see FAR better performance than having used it on 2.8 "upgrade" from the 2.7. 73, de Jim KG0KP ----- Original Message ----- From: "Bob Garceau" <[email protected]> To: <[email protected]> Sent: Monday, April 12, 2010 6:52 AM Subject: [Elecraft] 2.7 vs 2.8 > I'm getting a K3. > > > > Is is worth taking the hit and replacing the 2.7 khz 5 pole with the 2.8 > khz > 8 pole? > > Just to let you know, all the rest of the filters that I plan to buy will > be > 8 pole. > > > > Bob, W1EQ > > > > > > > > ______________________________________________________________ > 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 > ______________________________________________________________ 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
