I used that same 1.8kHz Inrad filter in the old FT-1000MP, where it was very much needed for SSB contesting. Because that filter is also compatible with the K3, I decided to make a new adapter board and try it... and am very glad I did! The K3 is configured to switch in the filter at a DSP bandwidth of 1.9kHz, and with the center frequency set to 1.25kHz it gives a very good balance between selectivity and intelligibility - so good, in fact, that the SHIFT and WIDTH controls hardly ever need to be touched for the duration of an entire contest. That isn't just one person's opinion; my wife and guest operators also find those same filter settings immediately comfortable, so they can go straight ahead and operate. >You won't be displeased. > I agree with Dale. Although a narrower roofing filter isn't essential (we all understand that), the 1.8kHz filter does make a difference to SSB contesting. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek ______________________________________________________________ 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
