K3 NB
Locked
 
|
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.

Just found it. 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?

Hi Mike,
yes, there are two KNB3s installed if you have the Sub-RX: one on the Main and one on the Sub. And yes, you can swap'em. 73, Olli - DH8BQA Contest, DX & radio projects: http://www.dh8bqa.de Am 16.05.2016 um 22:07 schrieb Mike Smith VE9AA: > 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.

Mike,
Yes, the KNB3's can be swapped. But if you'll be in there anyway, I'd strongly suggest that you first remove and then re-insert the KNB3 module in your main receiver first. Then try it out and see if the blinking "NB" issue persists. If not, you're done. Otherwise, swapping them and observing the results would provide some additional useful data points. 73, Dale - WA8SRA > Just found it. Tony, N2TK asked about the 2nd rx. Good on ya Tony.

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. 73, N2TK, Tony -----Original Message----- From: Elecraft [mailto:[hidden email]] On Behalf Of Mike Smith VE9AA Sent: Monday, May 16, 2016 4:15 PM To: [hidden email] Subject: Re: [Elecraft] K3 NB Just found it.

Mike,
Good work to have discovered where the problem lies. You might want to obtain a new KNB3 board and simply replace the one in the mainRX. Yes, you can swap the KNB3 between the main and the sub, so if you want --- Look in the K3 assembly manual as well as the KRX3 manual to see where they are plugged in - as well as how to remove the KRX3 to get at the KNB3 board on the main board. The process is: Remove the top cover Remove the KRX3 assembly Take the top cover off the KRX3 and remove the KNB3 Remove the KNB3 from the main and put it in the KRX3 (the top cover can now go on) Put the KNB3 that was from the sub into the main Put the KRX3 in place being careful that both the SubIN and SubOUT boards are in place. Reconnect the cables to the KRX3 Put the top cover on. Job done. 73, Don W3FPR On 5/16/2016 4:14 PM, Mike Smith VE9AA wrote: > Just found it. Tony, N2TK asked about the 2nd rx. Good on ya Tony.

Be sure if try to test before putting the KRX3 back in that you check the KRX3 install directions and replace the small jumper in the socket where the rear "extender" board goes. Else the radio won't turn on
