Your K3 has probably had these DSP changes for some time (assuming you have kept the firmware reasonably up-to-date). Future firmware releases will apply equally to both the K3S and the K3. Likewise, all hardware upgrades prior to release of the K3S have already been incorporated into K3 production. Hardware upgrade kits are available for older models - see the Elecraft website, which also states when each upgrade was introduced. The only only exception listed below is the redesigned AF output and driver stages. These upgrades were introduced in the new KIO3B module which now forms part of the K3S (a radical redesign which also includes USB connectivity for CAT and audio). The KIO3B will eventually be available for the K3 as well, as an optional replacement for the older KIO3. 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of >Stewart >Sent: 28 October 2015 07:42 >To: Wayne Burdick; Vic Rosenthal 4X6GP/K2VCO >Cc: elecraft@mailman.qth.net >Subject: Re: [Elecraft] K3S In-Depth Review Coming Soon? > >I am interested as to whether the corrected DSP AGC algorithms will be >available >for K3 DSP's. > >73 >Stewart G3RXQ >On Tue, 27 Oct 2015 13:28:19 -0700, Wayne Burdick wrote: >> 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.
