Elecraft K3 Build – Boards and Speaker Day 10
Assembly continues after the power on test everything was fine so let’s finish up this rig build. I didn’t have a full night to work so I’m going to get as far as I could. Looks like there are a few boards that need to be installed that mount to the front heat shield and then a few more on the main board.
In such a small and confined space it’s important to get things right because you don’t want to go in and have to change lager. I spent a little extra time making sure the boards and standoffs were mounted properly – all the pins in the right positions before pressing down too hard. I was extra careful only because these are small and sensitive parts of the build.
Got the noise blanker in as well which was one of the errors I had gotten during power on testing. Then it’s on to the top cover and speaker assembly. This is where I deviated from the book a little or at least I think I did. Getting the mesh for the speaker aligned and holes drilled was reinforced that you have to get right or you could have choppy or scratchy audio. I of course don’t want this to happen so I ensured that I got the holes marked and after popping small hole with a knife I bore the hold with a sharp Phillips head. This seemed to work well as I was kinda drilling out the hold without damaging the matt too much. The next step was getting the screws in – I did all four at once. Seemed to me if you could get them all in and put the radio down on a flat surface they would stand up long enough to get the fiber washers and other washers and bolds on and held… and tighten after. I can’t remember now but it seems that this was a different way than the book suggestion.
Last item I had time for tonight was to get the speaker magnet on – it was a simple step but one that scared the ……. Out of me. The magnet is strong to be prepared when you move it close it’s going to grab. Mine took off after the speaker and I had to pull it off twice to get it right. Again – not a hard step but one to be ready for ☺
Plenty more empty boxes and bags…. Only a few more to go – this is getting exciting.
Enjoy the movie of these steps:
