John, The order date of my K3S serial #10629 is January 28, 2016. So, I'm guessing your 105xx order date would be, depending on early 5xx or late 5xx, December 2015 or January 2016. Be aware John that the early K3Ss, lower than serial # approximately 10700 or 10800 (I don't remember the exact serial #) need some modifications to be up to current K3S production. The mods are the IMD mod for the K3LPA and KPA3A, the fan mod and the KPOD mod so the KPOD can be powered from the front panel KPOD jack. I just got my K3S back from Elecraft about two weeks ago after having these mods installed. I believe Elecraft will perform these mods for free except for shipping to and from Elecraft. If I'm incorrect on that I'm sure Don or someone on the reflector will chime in.
