Well-written drivers and interrupt handlers may cause some latency, but not enough to make an audible click. However, not every piece of software is well-written. For an informative explanation, see the post by "aj" at: http://forum.cakewalk.com/tm.aspx?&m=1935436&mpage=2 The instruction .pdf that comes with the latency checker has additional useful info. If you have problems due to DPCs, you can disable drivers, services and programs one by one until you find the culprit. It is a time-honored tradition to fault the operating system for problems caused by non-OS software, and this topic is a rich lode of such misplaced blame. 73, Tony KT0NY -- http://www.isb.edu/faculty/facultydir.aspx?ddlFaculty=352 ______________________________________________________________ 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
