Lyle, Thanks for the explanation. As with most hams, I like the sound of my own voice (!) and listening to a delayed version of my own voice on phones during a long contest, I find quite wearing. Would it be possible to menu-select the monitor output prior to any of the processing you mention? I've reverted to using my dear old TS-850 for phone operation because of this problem.

We thought it best to allow you to hear the effects of the IF signal processing, so delays are unavoidable. Most people do not notice as the K3 uses filters optimized to minimize delays. Note that Tx EQ adds zero additional delay. Like the Rx EQ, the Tx EQ just adds more constraints to the AF FIR filter generator. There may be opportunity to further redice delays by combining some filter functions. One of the items on my list of background tasks :-) ______________________________________________________________ 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
