There is no clicking artefact on received signals, only on my transmitted signal. Here's my set up: I'm using direct connection from K3 to my laptop. No interface, but I have a soundcard in a USB dongle, which I need to connect the audio in and out to my computer. I have Data mode A enabled and ALC set to 4 bars solid with the 5th flickering. Power output is set to 40W. Monitored IMD is good (-29 to-30) using KK7UQ device for off-air monitoring - the signal is otherwise clean. I have checked and can confirm that the clicking/popping is independent of: Line in Gain/soundcard audio drive settings; data mode used (PSK31/RTTY/Olivia - all are affected); digimode software application used (same with Fldigi, Airlink Express, digipan and HRD) and finally, I have USB soundcard dongles of 2 different manufacturers and the problem is present using both. Any ideas or advice gratefully received. I'd like to get rid of this TX clicking! 73 and thanks in advance, John VK7JB -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Data-mode-TX-problem-from-VK7JB-tp6787469p6787469.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net 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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
