What Else Do I Need to Build an “Option Ready” K2?
In Addition to Option Bypass Headers

This is by far the ques­tion we are most fre­quent­ly asked!  The fol­low­ing ta­ble lists all of the elec­tri­cal com­po­nents, con­nect­ors, mount­ing hard­ware, and mis­cel­la­ne­ous wire re­quired to make cur­rent (as well as pre-S/N 3060) K2s “Option Ready” for each op­tion.  The ta­ble al­so shows where to ob­tain these parts, ei­ther from the ac­tu­al Elecraft® options or from our parts kits

Be sure to read the footnotes for all of the options you aren’t get­ting with your K2, but wish to make it “Option Ready” to ac­cept.  Please don’t stress out if you find this a bit con­fus­ing.  It will all make sense in due time.

Feel free to contact us if you have ques­tions about what you need, or if you want us to con­firm that what you are plan­ning to or­der is eve­ry­thing you need, or if you would pre­fer that we just tell you what you should or­der.

Requires Either of These Kits Which Supply These K2 PCB Parts

1 A stock K2 is already “Option Ready” for the Elecraft® KIO2 option.

2 “Option Ready” support for the Elecraft® KPA100 option requires RF-P6 and RF-P3, both of which are provided with the KPA100.  If you have a stock K2, you will need both the Re­work Elim­i­na­tor™ Aux RF Plug and Aux 12V Plug kits to build your K2 so that it is KPA100 “ready”.

3 The Elecraft® KAF2 (an­a­log fil­ter) and Elecraft® KDSP2 (ad­vanced DSP) aux­il­ia­ry au­dio fil­ter op­tions both in­clude the same two K2 PCB jacks.  If you have a stock K2, then you will need the Re­work Elim­i­na­tor™ Aux Fil­ter Jacks kit to build your K2 so that it is “Op­tion Ready” for ei­ther of these op­tion­al fil­ter mod­ules.

4 Be­yond the K2 PCB parts re­quired for cur­rent K2s, the Elecraft® K160RX al­so in­cludes two re­place­ment caps which are only need­ed for “old­er mod­el” K2s.  These two caps are not included with the Rework Eliminator™ K160RX Parts kit.  In­stead, they are avail­a­ble via the Re­work Elim­i­na­tor™ Updated Caps kit.  If your un-built K2’s S/N is less than 3060, you should check the val­ues of these two caps to de­ter­mine if you al­so re­quire this kit to make your K2 “Op­tion Ready” for the K160RX op­tion. 

5 Pre-S/N 4060 K2s re­quire up­dat­ed firm­ware to make them “Op­tion Ready” for the Elecraft® K60XV op­tion.  This up­dat­ed firm­ware nor­mal­ly re­tails for $54, how­ev­er it is avail­a­ble for free to own­ers of pre-S/N 4060 K2s who pur­chase the K60XV.  Be­cause of this, we rec­om­mend only mak­ing pre-S/N 4060 K2s K60XV “ready” if you al­ready have the K60XV and the up­dat­ed firm­ware.
