amatureradiokits enclosure question #ubitx #ubitx-help

Dean Souleles
 

Hi - I ordered a universal ubitx enclosure from amateureradiokits.in. Its a beautiful case and all the parts needed for a nice clean build are included. However the PCB they sent for the front panel display has a couple of problems. On the analog 8 connector port the hole for pin 6 is missing and the pin 2 and 3 solder pads are shorted. If I read the schematic correctly for the ubitx pin 2 is ground for the mic and pin 3 is ground for the volume so the short won't matter. And pin 6 appears to be unused. So if I clip pin 6 off the pin strip I think I should be able to proceed with the build, no harm, no foul. Yes? Thanks in advance from a newbie builder.

Looks like a board hand-redrilled for correction post-manufacture: quality-control rework? or are they all hand-drilled? J2 pin 4 and the centre pin of J5 are out of line, too.

I didn’t have to cut any pins in my two kits...  strange how those holes are not aligned...


I agree with Dexter,  looks like this was done by hand.

Some are out of alignment on my boards but all the holes are there.Just bear in mind that on my boards I had to add a jump link to give both channels on the headphone socket.As it stands you will only get audio on one side..

I read this blog for information and you just provided something new about the audio board I was unaware of, the fact that the headphone circuit on the board lacked a trace to provide audio to both sides of a stereo headset. In final stages of uBITX construction so would have found it eventually, thanks for the heads up

Thanks Ian - for a newbie - what did you jump exactly?

Hi Dean, sorry for the delay,I had to find my spare board to photograph for you.the board is unsoldered and without the link but hopefully you can see from my hand drawn diagram that you join the unused pin on the pcb to the one that comes from the connector.  I suggest you place the Jack socket in place and then turn the board over printed circuit side up and make a short link and place the wire in the appropriate hole.you only then need make one solder joint for each.  Good luck with the project and any more questions do get in touch.Best 73.

I did the same with a small length of insulated wire and seams to be correct but it was added after headset socket was all soldered in. ver. 5 uBITX in final connection phase some more work to be done, T/R led, antenna coax, and one ground connection assemble case and smoke test 🥶ha. Keep working on it your almost done

Ian,

Perfection!  Exactly what I needed to know. Thank you.  My initial build is nearly complete.  Awaiting the replacement front panel board from amaturradiokits - but everything else is assembled - so I can still place the link before I solder in the jack.  Any thoughts on my original post? Looks to me like ana

Hi Dean,

Here are my thoughts, the analog connector does not need pin 6,red wire,so if you have the leads which are terminated in a socket each end,just remove pin ,6 from the connector you need to solder in,it just pushes out.Pins 2,3,6 if present and 8 are all ground connections.Due to manufacture tolerances the 8 pin connectors may well be difficult to fit and are a tight fit against the end of the Jack plugs.Care and patience is required and I would completely assemble the board to check for fit before any soldering.Hope the pictures help.Both 8 pin connectors have the purple wire to the left hand pin when viewed from the front.  Best 73.

      For Dean KK4DAS.   Hi Dean, I don't know which case or display type you will be using so I just need to mention this.The connectors on the board are designed so the plugs fit vertically and on mine with the standard two line display there was insufficient clearance for the connectors to fit vertically.I suggest you fit all the parts in situ,main board,display assembly,Jack board with sockets and cables and carefully check for physical fit.Best 73. Ian

I used 90 degree pins instead of the vertical ones provided. On the "tall" case from Sunil, there is plenty of room. No data on the smaller cases.

Hi Ian - starting out with the kit 2 line display with the default front panel.  I might change it out for a Nextion display later and will order a replacement front panel if I do that.  Thanks for the tip on pre-fitting - I sure hope it all fits - that was the point!

73,

Ian - 

This is perfect and exactly what I was asking for.  I traced the pin connections and looked at the schematic and came to the same conclusion.  I am not confident enough in my electronic build skills yet to go with my gut.  It has only been about 30 years since I picked up a soldering iron for anything complex!    I am having fun with this kit.

73!
