Tait 8100 VFO Display Modification

These are the display modifications required to the display, so, once done it will fit on to the main board and case when it is time for assembly. This page is soley for the VFO kit for the Tait 8100.
You can find the main project page here Tait 8100 VFO Interface .
Please note, I take no credit for this modification and please read my Disclaimer and you understand it before continuing.



Photo 1. Display.

This is the display before any modifications are done. Read through these instructions FIRST and then do the modifications so you are clear on what to do.


Photo 2.

Photo 2 shows a close up of the front side corner that needs to be cut off. Be very careful here not to cut to close to the display itself. The cutters will clip off the corner in one snip.
Using a medium size pair of side cutters, cut the corner as shown in the photo 2. and photo 3 shows the rear side cut off.
Tip.
You can mark the board first with a vivid marker, to double check you have the right corner, before you cut.

Photo 3.

Shows the rear of the display with the modified corner cut off the PCB board.

Photo 4. Links J1 and J4 ONLY are Required.

In order for the display to work correctly you will need to check which links are joined. You will see in the close up in photo 4, these links marked J1, J2, J3, J4.
We only need J1 and J4 to be made as seen in the photo. Some displays already come with these links done so if your display shows solder over the half moon ONLY on J1 and J4 then they are in the right place, and you do not need to do anything.
If solder is on any of the other links, J2 or J3 then you will need to remove these links.

Removal of the Links.

You will notice these links are made by soldering 2 half moon shapes together.
The best way to remove these links is by using solder wick. Place the solder wick over the link you are to remove and apply the soldering iron and wiping off the excess solder. Make sure the link is completly removed.
The end result, you will have only, J1 and J4 links joined.
If you need help with this, see Rob ZL1RJS or your local club


Photo 5. Bending the Tabs Over

Photo 5 shows a close up of the tabs that need to be bent over. Be carful on doing this. There are 8 tabs in total that need to be done. Using a small pair of pliers, turn the tab to nearly straight and then push the tab over flat, keeping the display flat on your work surface. Do this to the other seven tabs. See photo 6 and 7
