Up until now they have not worked mostly due to my SIOC script not working for some reason. But once I got SIOC working I noticed that the script allowed for the ADF/ANT indicators on my radio to be put in to use. So I decided to make a new version of my ADF-radio that included the AFD/ANT indicators next to the digits.
I found some dark tinted foil on ebay last month and two layers of that film really made an improvement compared to the reflective sun film I have used up until now. You can see it on the picture above where it not is possible to se the 7-segment units.
So I better start remaking all my radios so they all use this dark film.
I also found out that in order to get the digit working the specific pin on the fourth 7-segment unit must be hard-wired to the master card. And furthermore you must cut the connecting lanes (Or whatever they are called) on the 7-segment PCB’s that I use. But it works fine now.
The radio is – as all other panels I have made – build in layers. I’ll post a video about it later. But you can clearly see here that there is a layer of plexiglass behind the panel.
This layer of plexiglas holds must switches and the LED-strips used for backlighting.
As you also might notice the panel is a mess in wired. There are 5 switches on the panel (3 switches + encoder + encoder-push). I normally make a backplate with all connectors on. Then it is easy to connect with dupont-cables.
For this panel I decided to also make connectors for the 7-segment displays. Normally I connect them directly from the PCB to the Display-card.
But sometimes this solution results in loose connections later down the road.
So with this middle station I hope to prevent this later on. As you might see from the picture the ADF/ANT-indicators require a resistor (330 ohm). But the decimal-points (The last two pins on the LED-row) should not have a resistor connected. It takes 5v.
