Ditto. W4TV (?) measured the 250 (actually 370 Hz) versus the 200 and the latter had more rejection at ALL frequencies, even though it's only a 5-pole. I only use my 200 ~1% of the time (500 Hz 8-pole the other 99%) but there are times when it's nice to have (such as large simplex pileups). Someone previously commented on the 1000 Hz (actually ~1100 Hz) for CW. I had one but found it too wide to be of much use. If there are NOT a lot of strong signals around, the stock 2.7k will work about as well. If there ARE a lot of strong signals around, the 1000 allows too many of them to desense the rig. This is especially true if you use a low pitch as I do (3-400 Hz). In that case the bandpass is shifted upwards from 200 Hz such that signals as much as 1000 Hz above zero beat will desense the K3 (e.g. a 200-1300 Hz bandpass for a 300 Hz pitch). 73, Bill -- View this message in context: http://n2.nabble.com/My-Five-Filters-tp4586377p4586571.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
