Hi Darryl, There were an awful lot of mods that might have been needed depending on the serial number. Even if the unit had no mods it still might be a good purchase as long as the price reflects the money you'll have to invest to upgrade it.
The DSP board upgrade is considered very important by many K3 owners and it is not listed with the other K3 mods on the mods and notes page. You can find it only on the spare parts page. It is called K3DSPUPGD. The DSP mod is not listed here (??): http://www.elecraft.com/K3/k3_app_notes.htm K3DSPUPGD can be found here: http://www.elecraft.com/order_form_parts.htm#K3%20Parts 73, Mike K2MK Darryl J Kelly wrote > Any problems with buying a K3 with a low serial number, say that has > had hardware updates and alignments? > Darryl, KK5IB -- View this message in context: http://elecraft.365791.n2.nabble.com/Low-Serial-Numbered-K3-tp7593319p7593329.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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]
