G'day, Please correct me if I'm wrong but my understanding is that the settings of the RX equaliser work within the DSP block and will do little to suppress the higher frequency products that contaminate the subsequent audio out of the DAC. This is the domain of the analogue LPF module that has finally emerged kicking and screaming.

If that's the case, then the K3's receiver equalizer can be set up to mimic a pink rolloff which is -3 dB per octave. 50 Hz : + 9 dB 100 : + 6 200 : + 3 400 : 0 800 : - 3 1600 : - 6 3200 : - 9 ______________________________________________________________ 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
