I'm not near my radio to try it, but try setting it to NOR 08 and see if the problem goes away. I know it is intended for QSK, but it does delay the onset of RF so it may shorten the keyed elements even if you are using ptt. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ______________________________________________________________ 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
