I have decided to order an extra KNB package from QRP Project because it only costs 44€ and they seemed to have it on stock, ie. quick delivery.
I can admit now that I simply couldn’t resist anymore. A week ago I ordered a K1 directly from Elecraft and today I could pick it up at our local post office. I tried to order the minimal package consisting of the K1, the LCD backlight modkit and the noise blanker module.
