I have built K2 4670 working great, soon to add the 100W/tuner. To learn more about this wonderful hobby, I also just bought an original K2 # 389 with the internal battery kit. This will be my QRP radio. This is also obviously a Rev A model. It came with the following un built modules.
KNB2 Rev C dtd 3 Feb 2000 KAT2, Rev B, dtd Feb 14, 2000 KSB2, Rev B, dtd Nov 15, 199 >From the Elecraft web site, there are obvious upgrades (A-B kit and all the others) that I will incorporate, but are there any upgrades to the un built modules? Or after doing all the basic K2 mods, should I buy the latest modules to this K2? All suggestions/plan of action as to a course of action would be appreciated. 73, Allan Bacon KI4HRN -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Don Wilhelm Sent: Friday, January 06, 2006 6:06 PM To: Craig Black; [email protected] Subject: RE: [Elecraft] Need advice - upgrade vs. new K2 Craig, If you plan to keep it, I would say that you should upgrade the current K2 no matter what - and do ALL the upgrades and all the optional pieces too - including the Keying waveshape change, the PLL Temperature compensation change and the Extremely Strong signal Handling diodes (no parts kit for this last one, but it takes only 2 1N4148 diodes). You will end up with a K2 that performs just like a new one - it will only have a few more components mounted on the bottom of the board, and you will not have an AGC Threshold pot (unless you squeeze a tiny trimmer in there). Do change the Filter crystals too. No-one will know it has been upgraded unless they know what to look for. I can supply photos of my fully upgraded SN 0020 should there be any doubt. As far as a new K2 - well, if you want 2 of them, then the upgrade plus the new build is the only way to go for economy. I don't know what financial constraints you may have, but the outlay for an upgraded K2 plus a new K2 will certainly be less than buying 2 new ones! 73, Don W3FPR > -----Original Message----- > > This falls into the "help me rationalize what I want > to do" bucket, but make it factual. > > I am an owner of a K2 sn 1014 who loves to build.
