I used the Elecraft 500 Hz 5-pole filters for ~18 months but switched to Inrad 8-pole 500s when they became available. I'm also probably not a good benchmark because I do serious contesting and DX-ing on 160m (the band that separates the men from the boys). I do still like my 200 Hz 5-pole for extreme (<1%) cases. Other bands are not as critical since they don't attempt to pack hundreds of S9+30 signals into 50 kHz and DX signals are stronger. I can see the day coming when 200 Hz may become the new norm for CW contests as more people use clean rigs like the K3 and zero beat more closely (due to spectrum displays or internal zero beat indicators like the K3's CWT). 73, Bill -- View this message in context: http://n2.nabble.com/CW-roofing-filters-tp4588621p4588862.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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
