I'd like to think that there wouldn't be such a problem with an early unit. Mine's s/n 24, so the first kit from Oct, 2007. Every applicable mod has been made to it, and I had one of the techs go over it looking for update opportunities. He couldn't find any, and everything was in spec.
Elecraft may be the first Amateur Radio transceiver manufacturer to ensure that there is no stigma associated with a low s/n transceiver, as long as it's kept up to date. Other manufacturers develop upgrades that will only work on serial number so-and-so and up. We don't have that problem with the K3, something else that sets it apart besides its specs and performance. If you're expecting to buy an early K3, I'd suggest getting copies of all the mod instructions and using them to inspect your candidate K3 for mods and upgrades. This at least is reassuring, if not downright necessary. Some of the PCBAs have different fab and assembly rev levels. Except for the DSP(s), I was told that all other board changes over the years maintain the same specs. The DSP upgrade actually improves performance at audio frequencies, and there is an exchange program for the older rev DSPs that defers some of the cost of the new ones. 73, matt W6NIA On Mon, 22 Sep 2014 22:18:27 -0500, you wrote: >Any problems with buying a K3 with a low serial number, say that has >had hardware updates and alignments? >Darryl, KK5IB >______________________________________________________________ >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] Matt Zilmer, W6NIA -- "Give me six hours to chop down a tree and I will spend the first four sharpening the axe." -A.
