Mike, They can be swapped. You need to take out the second receiver to get to the one on the main rf board. One screw takes each one out. Make sure on the rf board that there are two lockwashers between the NB standoff and the rf board. Take the screw out and the bard pulls out. Swap them and put it back together. See if you swapped the problem.

Tony, N2TK asked about the 2nd rx. Good on ya Tony. At least I am making headway. Can the KNB3's be swapped guys or is there a lot more to it? Mike VE9AA Mike, Coreen & Corey Keswick Ridge, NB From: Mike Smith VE9AA [mailto:[email protected]] Sent: May 16, 2016 5:08 PM To: '[email protected]' Subject: K3 NB I wish I could find the email from this weekend from the fellow who asked me if the NB works on the 2nd receiver. I hadn't used the 2nd receiver really much at all (only had the rig a few days) and was hesitant to play with it until I learned a little more about the rig in general. Anyways - an AHA! -moment. The IF Noise Blanker actually works pretty well on the 2nd receiver. So, that leads me to believe that there's something about the primary rx that is not quite right. Are there two KNB3 blanker boards in an early K3 with two receivers? Can I revert the firmware back to 4.83 (I saved it to a folder before upgrading to the latest) and see if somehow the blanker was maybe shut off, then turn it back on, then re: upgrade the firmware? I just knew there was something up! BTW, it was only the first day I had the radio that I heard relays clickity clacking when I had the NB engaged. Now I just transmit once or twice, and the NB letters flash. (no relay noise) 2nd receiver NB seems fine. Is it easy to find the KNB3 board(s) ? Tnx to whoever it was who asked about that.(kudos and give yourself a pat on the back) - you were the only one in 25+ ops to suggest that). At least now I know the NB does in fact WORK in these Elecraft beasts..but only in my 2nd RX.
