As another data point in this discussion... I operate 100% CW with my K3, which is equipped with 200, 500, 1000, and 2.7KHz filters.
During FD 2010 I made 400+ CW QSO's during my two 4 hour operating shifts. The great majority of that operating time was spent with the DSP bandwidth at 600-700 Hz (and the 1KHz crystal filter.) Only once, when digging out a weak one, did I narrow the bandwidth tight enough to engage the 200Hz crystal filter. FD may not be the ultimate contest environment test, but it's busy. Calling stations are often pretty far off zero beat in FD, so one needs a fairly wide bandwidth to hear many of them. The 1KHz crystal filter combined with the K3 DSP did a swimmingly good job this year and in FD's 09 and 08. Would a 750 Hz crystal filter be better? Perhaps, but I'm quite happy with what I have now. 73, john WA1ABI ______________________________________________________________ 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
