C46 is part of the new "Key-Click" mod which requires different firmware in the MCU than you have.
Trying to incorporate all of the newer mods is difficult for an experienced kit builder/technician. I would strongly recommend only following the errata that came with your kit. If you are not sure if you have it, then request it from this reflector, include your serial number and if you have a copy of the purchase order or box, the date it was sent. Build it first this way and get it working. After it is working, then, look at the Elecraft MODS page and the various web pages that have listings of mods and add those that are "Elecraft" endorsed. Many of those incorporated into the newer K2 are these mods and are available on Elecraft, along with the necessary firmware (New MCU) when needed. Many are not needed if you are going to stay QRP. Not all MODS are necessary, for example, there was a long discussion on the need for the key-click mod. It passed ARRL testing without, but if you are going to add the KPA100, I would add it. But make the basic K2 work first. Rich, KE0X _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
