Assembling K2 Currently Elecraft places at the disposal of the radio hams a kit making it possible to build a HF transceiver whose qualities with the height of best are produced available on the market such as Yaesu FT1000MP or Ten Tec OMNI VI. Envisaged at the origin exclusively for QRP (5 Watts output,) Elecraft proposes a 100 watts output power amplifier. We advise you to return visit to the Elecraft site to discover the little marvel - click on Elecraft Elecraft delivering K2 only in the shape of a kit, that worries about many OM which fear to encounter insurmountable difficulties and not to lead in their project. We built two K2, the first in January 2001 and the second in April 2002. The experiment is enthralling and the results are quite higher than what we wait. You will find, below, some councils which will allow you to have the certainty to build successfully this transceiver.

Build aKX1, The new QRP transceiver Elecraft Click on pix ultra-portable transceiver KX1 cliché F6BLK How to order the K2 The order can be done through internet or by mail. The order form is available on the Elecraft web site and the different amount are automtically computed (in US $). Dont forget to choose the transportation mode. The payment can be done directly via internet (secure site) if a credit card is available (Visa, Mastercard or American Express). We currently use this way of payment without any problem, in addition of taht, the change fees are low. Dont forget the custom taxes which will have to be paid at the delivery, directly to the transportation man. (Chronospost, Extand...) Average custom taxes for France : The taxes are moderatly low (approx 12 Euros for a K2), however the VAT is quite high : 19.6% of the K2 price + 2/3 of transportation + custom taxes. Anyway, the final amount of the K2 kit stays very attractive...Now you have just to assemble it, this is exactly the next topic.... Guarantee That's sure, the transceiver has a full one year guarantee...Please read carefully (Assembly manual page 4). Unshipping the kit What an exciting moment ! You have anxiously discovered the package you'd just received. You must check is eveything is OK and particularly the all components. It takes some time but it is very necessary and also allows to become familiar with the different items (caps, toroids...)
The different components are packed in platic bags which are quickly identified from their stickers : - Control , - Front Panel, - RF Board, - Miscellaneous, - Wire. In the assembly manual, you will find out a complete inventory of the components in Appendix A, ie : "K2 Control board part list". First step :become familiar with the component marking. For instance : 0.001 capacitor = 102, 0.01=103, 0.047=473 etc... Second step : keep at hand some small plastic boxes and split the contents of the same bag inside the boxes, sorting the components by value and type : one box for the 102 cap, an other for the 103 and so on. Dont forget to check the corresponding box in Appendix A. Dont forget to put a sticker on each box and avoid strongly to mix the bags...! The resistors are delivered in the order of assembly. It is unnecessary to do the inventory. They will be taken one after the other during their use on the circuit boards. Everything is clear ? Nothing is missing ? Go to the next step. Something is missing ? A component is bad ? Please send immediatelly an email to Elecraft describing precisely the trouble, cliquez sur e-mail Next week, you will receive the missing component (no fee). "Front Board" The main and only difficulty is to put in place the five potentiometers. Each one has four pins which are slightly large tha the printed circuit holes. So a moderate to high pressure is required in order to fit the pot inside the printed circuit. Pay attention to leave the axis clear during the action.
Control board : No difficulty
