For those who spend much time fretting about the
efficacy of the K3's Noise Reduction system
('worse/better/different settings' since last
update....) why not have a play with the Rx
equalisation settings?On cw with a 700Hz offset I find changing the 800Hz 'channel' has a marked effect on received audio without NR as you'd expect but the difference when the NR is engaged can be quite remarkable. I can vary this between seemingly attenuating the received audio somewhat to increasing it substantially as if an extra stage of AF amplification has been switched in. Presumably a few dB extra at the sidetone frequency is giving the NR more to work on.... I haven't tried phone but it obviously won't be so simple; trial and error I guess. 73, Stewart Rolfe, GW0ETF (K3 #145 with all the latest) _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
