Dear All, I am debating if I should get a narrow filter for PSK and RTTY work. Currently the most narrow filter I have is the 8 pole 2.1.
I am thinking about an Inrad 8 pole 500 hz to add to the K3. I am not having problem, however, the more I use these modes I find that you will have very close signals for PSK and I am wondering if this will help in pulling weaker signals in, instead of depending so much on the DSP. I also want to know will this filter also be in use when in TX mode to help limit the bandwith. I wonder this as I worry about bumping up the power as signals are so close and I do not want to interfer with others. I am asking because I am hoping users can give their experience working these modes before I purchase the filter. I dont want to make the same mistake I made with the 2.1 filter for SSB where I now wish I would have purchased the 1.8 filter. Anyway I will appreciate any and all feedback. Thanks Don Don KD8NNU ______________________________________________________________ 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
