James, The full procedure is a bit long for an email, but please see page 46 in the current version of the K3 Owners Manual, which is available under Manuals and Downloads at the Elecraft web page. All of the filter setup functions are accessed through the CONFIG menus. There are 3 key steps to follow: (1) Tell the K3 where to find the new filter (slot FLx), its bandwidth and its frequency offset; for the 8 pole filters such as your KFL3A-400 there is 0.00 frequency offset, (2) Enable the filter for receive mode, and (3) Activate filter loss compensation (typically 1-2 dB for the 400 Hz 8-pole filter). You shouldn't need to alter the Transmit Crystal Filter Selection settings if you have already done this procedure with the stock 2.7 kHz 5-pole filter.
Enjoy the new filter! 73, Mike, K8CN -- View this message in context: http://elecraft.365791.n2.nabble.com/k3-filter-install-tp7563719p7563779.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
