400Hz is my favorite CW/RTTY filter. I also have a 250Hz but if you read the archives you will see that it is not much narrower than the 400. If you are concerned about the cost this is worth looking at. I have the 2.1KHz and 1.8KHz SSB filters. Of course the 2.1 sounds better, I switch in the 1.8 when QRM worsens. I think having both is useful.

My first priority is to add a couple to the main receiver, since it is the biggest chore to get to. I plan on a 250 Hz CW filter, but am going back and forth between the 2.1 and 1.8 kHz filters. I know that narrowing the DSP to 1.8 gives a really difficult to understand voice signal, while the 2.1 allows in more adjacent signals. However, the roofing filters may not behave in the same manner. For example, the 1.8 could be set to turn on at 2.1 to take advantage of skirt shape. I primarily DX, and operate in some contests as well. I know SSB contests really need a narrow SSB filter. Any suggestions on the matter from those who have gone this route before? 73 de Chuck, WS1L ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
