Windows has a problem doing real-time things, and Delayed Procedure Calls (DPCs) often produce huge latency spikes, resulting in audio pops. Other OSes may have similar problems, and may or may not be called the same thing.
If you are using a Windows computer to send Tx audio to your K3 (or any other radio) and you hear occasional pops and crackles in the Tx (or Rx) audio, do a web search on tuning your OS to minimize DPCs. 73, Lyle kK7P > Yes, I've always had those same pops on RTTY. ______________________________________________________________ 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
