Almost completed building my low band QMX and the usb connector soldering looks poor. Hans, is this what you have mentioned? Do you advise I touch it up?
Also, I found the BNC connector needs to be fitted? angled slightly forward, so as not to foul the display board. I'm a cw op, no digi modes. Richard G4PCE |

Yep. Mine looked the same.

Took Han's advice and touched them up. Super pointy iron tip, turned down the heat a bit and easyyyyy on the solder. I have a bit of 0.015 inch solder. Goes fast. I do use a head lamp magnifier, board holder armature and anchor my little fingers somewhere on the edge of the pcb or armature when possible so my iron and solder feed motions are as steady as possible. Easy to create bridges here ... Yep did that also in two places though they were minor. Just reheating one pad side briefly with a clean tip that has no solder on it caused the bridge to whisk itself back into the heated pad. Whew ... In hind sight, might just leave them as is and see how it works on startup. Can always go back and touch them up.? Greg KI4NVX

I've mentioned this before: before shipping, all boards have their bootloader programmed and verified, and that there are no shorts on the 3.3V rail, and that there is successful USB connectivity. The soldering of the USB connector looks rather bare but there IS a connection. My recommendation to touch up with some extra solder is only to strengthen the connection which looks a bit delicate for my liking.? 73 Hans G0UPL On Thu, Mar 14, 2024, 7:24?PM Greg McCain via <gamccain50=[email protected]> wrote: Yep.
