Contests aren't the best setting for CW decode, imho. However, if you tune the CW slightly higher than the CWT indicates it seems to improve decoding when there is band noise present. If you minimize the passband to 50 or 100 Hz, this also helps reduce noise in the decode channel. With the passband minimized, the decoder gets good results with the CW and CWT matching.

I never have been able to get the decoder to do much for me, even during a contest. -- Hisashi T Fujinaka - [email protected] BSEE(6/86) + BSChem(3/95) + BAEnglish(8/95) + MSCS(8/03) + $2.50 = latte ______________________________________________________________ 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 ______________________________________________________________ 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
