Recently we've seen an increase in interest in the changes to the 80 and 160 meter filtering added to the KX3 in October of 2012.
Most operators who have the older circuitry will never experience band conditions bad enough to warrant making the modifications, since even in that case, the KX3's dynamic range would put it in the top ten on Sherwood's list (about 90 dB at 2 kHz). But if you might be a candidate for the changes, please the following document carefully: http://www.elecraft.com/manual/KX3%2080M-160M%20Rx%20Improvement%20-%20Owner%20version%20B.pdf 73, Wayne N6KR ______________________________________________________________ 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
