just wanted to chime in that i am having the same problem with my K2 that i have seen several people (most recently TF3KX) have been having.. the problem being that a newly built K2 has massively reduced sensitivity..i have been working with gary over the past week, and we almost have this thing solved.. unfortunately, it’s now the weekend, so elecraft is probably closed until monday. but man, i would like to have this thing running, and off my bench by this weekend..really quickly, all my voltages match what they need to be, based on the chart in the manual..i have double quadruple checked all my parts and placements, and everything is go..here is the one clue that i think someone might be able to say.. “oh! i know what that is..”the last suggestion gary made to me before the weekend is to touch T7 with my finger.. when i do this, the volume should go up..here’s the trick..when i touch T7 with me finger, the volume goes down to almost silent..i have septuple checked T7 for correct orientation, etc..so i am hoping this clue will jog something in someone’s mind this weekend..thanks!73 de kb8qpt

    Hi, I’ve got exactly the same problem with my K2 6471 you described here. Did you find/get a solution yet? I connected a noise generator and got S5 on the K2 and S9+50 on the other equipment here…

    Good luck with the rest, I hope you can help me.
