he shopping list for the complete transceiver is quite long:
- Case – reused from the old power supply project
- Power supply – Meanwell switch mode module bought at a radio rally
- USB sound card – Behringer card, bought at a music store
- USB hub – found one lying around somewhere
- Controller & LCD – Arduino Micro, ordered online
- Screen for LCD – Rescued from a defunct printer
- Electronic control unit – Aluminum case, PCB ordered online @ Reichelt
- PA heatsink – bought at a radio rally
- Case for LPF – from an old cable TV module
- Fan – Rescued from an old PC PSU
- Dust filter air outlet – ordered @ Reichelt
- Power supply for PA – PowerOne Switch mode power supply
- Various components, switches, connectors, wire, cable, mostly available in my (junk) box.
After I emptied the 19″ casing from all the stuff that made up the power supply, I fitted all the parts in the unit. The box was already full of holes, but it turned out that I had to add some more. It was a little bit of a puzzle, but in the end everything fitted neatly. A new front panel was custom made, since the original had too many holes already. A few hours of drilling, jig-sawing and filing were needed to make the holes for the air outlet, LCD unit and on-off switch. After everything fitted, I spray painted it. Also the top cover got a new layer of paint, as it had suffered quite badly from its stay in the garage for so many years.
In the end, I am quite happy with the result.
