Lance, As I noted in a post on this topic to the WSJT list, VOX works just fine for WSJT signals fed to the line input with well-behaved rigs and well-behaved amps. By well-behaved I mean having suitable delays between a TX line controlling the power amp and the beginning of RF at the output of the exciter, AGC within the exciter that prevents power spikes at the beginning of TX, and fast, dependable antenna switching that positively prevents hot switching. The Ten Tec and Alpha amps have done that for at least three decades, and so does the Elecraft KPA500. I use nothing but VOX for digital and SSB modes with my K3s driving Titans during contests, and my KPA500 for casual operation. During the recent ARRL RTTY Roundup and WPX RTTY contests alone I made nearly 3,000 QSOs, and it's been at least 3-4 years since I replaced a vacuum relay in one of the Titans. 73, Jim K9YC ______________________________________________________________ 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
