This "which filters do I need" questions are getting out of hand.
We are dealing with a pro Formual 1 car here. Problem is that often we *are not* F1 technicians, nor do we own a 'suitable racetrack' or have the driving qualities and lasting experience. Stop the nonsense discussions. SSB; the 2.7 Khz is perfect ** CW; go for the 400Hz and if weaksignal/extreme contesting is required; the 200Hz 5pole That is all you need. Stop discussing at this point. Get on the band for crying out loud! Note: my Orion has a perfect 4 pole 600Hz filter which performs perfect. Now do I think about a 10-pole 200Hz ?? Start the discussion again in 6months or so, when true live experience over a longer period of time is available. '73 Mark, PA5MW ** tested K3 extensively during VHF weaksignal, and 160m CW contesting from december 2007 till last weekend. *** compared K3 to Orion; like both, but they are different. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
