We've made several changes to improve audio over years, and a K3S incorporates all of them:
- K3: improved 12VDC decoupling to the AF amp - K3: added a dual low-noise LPF to eliminate residual sampling noise (mostly at 12 kHz) - K3: corrected DSP AGC algorithms, which were non-monotonic at some signal levels - K3S: redesigned AF output and driver stages for lower IMD Taken together, these changes provide a low-distortion, essentially flat audio passband. Most other modern transceivers use the same (or similar) class-AB final AF amp devices that we use in the K3/K3S, so how it sounds comes down to how RX EQ is set up, as well as the LO-CUT/HI-CUT (or shift/width) settings. 73, Wayne N6KR On Oct 27, 2015, at 1:10 PM, Vic Rosenthal 4X6GP/K2VCO <[email protected]> wrote: > Operators disagree about K3/K3S audio. ______________________________________________________________ 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 Message delivered to [email protected]
