K3 mods timeline
Locked

I was just on Elecraft's website looking at the K3 mods and parts order
pages. Is there a list showing which mods were installed in reference by serial number or build dates? The parts order page only indicates that these mods are "included on all new K3's". I have factory-built serial number #3215 and wanted to bring mine up to current build status and want to know which mods I should perform. Any info would be appreciated. Thanks.

Certainly, that list exists. On the opening screen (or any others) of
the Elecraft site, click on "K3 Mods + App Notes". If the information listed in the 3rd column is ambiguous, look to the 4th column, You may have to open the application note listed and read the contents to determine if it is installed on your K3. There is some difference in serial numbering between factory built and kit K3s, so some element of serial number ambiguity may exist, and cannot be easily resolved except by examination of the K3 in question. 73, Don W3FPR On 9/5/2011 1:49 PM, [hidden email] wrote: > I was just on Elecraft's website looking at the K3 mods and parts order > pages. > Is there a list showing which mods were installed in reference by serial > number or build dates? > The parts order page only indicates that these mods are "included on all > new K3's". > I have factory-built serial number #3215 and wanted to bring mine up to > current build status and want to know which mods I should perform. > Any info would be appreciated. > Thanks. > > Mike AC6JA > K3 #3215 > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

An educated guess is that you need the top 4 listed here: http://www.elecraft.com/K3/k3_app_notes.htm This is based on the bottom 3 which state "about 01/09/09", your S/N #3215 and a VY2SS post: "Elecraft K3 ser#3408 came into existence today September 14, 2009!" All 3 RF Board mods are easy to determine by inspection...easily accessible by removing the bottom front panel. You may also want the K3DSPLPF kit to bring your Rev C DSP board up to Rev D. See: http://www.elecraft.com/K3/mods/dsp_rev_c_information.htm ...as well as the K3SYN Stiffener Mod (fixes microphonic coupling from the speaker into the K3SYN): http://www.elecraft.com/manual/ELECRAFT%20KSYN3%20Stiffener%20Mod%20Rev%20D.pdf All of the above except the LPF kit are relatively easy to install. Unless you hear a 12 kHz artifact in your audio, you probably can skip the LPF kit which is more complex. The extended low end DSP audio mod is already in your Rev C DSP. Just to be safe, I would confirm the above with Gary@ or k3support@ elecraft.com. 73, Bill W4ZV |

You may also need K3VFOFILTERKIT K3 VFO Tuning Noise Filter Kit which was implemented in August 2009...again easy to determine by inspection of the RF board mentioned below.
