The K3 DualPB filter for AFSK or FSK mode should work fine at this data rate. The sidebands will be slightly wider due to the faster keying speed, so a 200 Hz roofing filter is probably a little tight. 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
