The DPB filter creates two narrow filters centered on the RTTY tone pair. For it to work well, you have to tune the radio very accurately. Some RTTY contesters report that the DPB helps in difficult conditions. If you use AFC or other receive features in the RTTY program -- anything other than tuning the K3 precisely -- performance may suffer. 73, Lyle KK7P ______________________________________________________________ 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
