I have just received KX1 Serial No 2711 and started building. I couldn’t believe just how ‘professional’ the kit is. Apart from the wonderful set of instructions, it contained paper envelopes with the components, each with a label stating who had packed it, and even a sheet of sand paper for stripping the ends of the torroid leads!
Following the detailed instructions was quite straight forward. I completed Part 1 of the build over two evening sessions.
Careful attention needs to be paid to ESD precautions as there are a number of static sensitive components in the kit. The three surface-mount components came already installed.
At the end of Part 1 of the build process came the first test. A series of resistance tests with a DMM were done and when readings obtained indicated there were no short circuits or other mistakes, power was supplies and voltage checks done. Then it was time to access and test the configuration menu and the digital display.
Everything tested according to plan, so now it’s time for Part 2 of the build; the receiver circuit.
