Remote SDR - case

thingiverse

This is a 3D printable case for F1ATB's Remote SDR project. André made a great development by designing a Transceiver between 70 MHz-6GHz and other great features such as web interface. More is available here: https://f1atb.fr/index.php/2021/05/03/remote-sdr-v2-2/ I can only recommend you to spend some time and get familiar with his project. Version 2: I added a 60x60x15 mm fan to the case to cool the Orange PI. Without any cooling the Orange PI will overheat and shut down at 125 Celsius. Just with passive cooling the heat balance will be about 90 Celsius. With the passive cooling bodies and the fan it does not go warmer than 60 Celsius. This is perfect even for continuous duplex operations. Version 3: The design has been changed for hosting Raspberry PI 4. This seem to be more available than Orange PI. I added also to my device a PoE hat. I find one that support not just RPI but also has 12V 2A output. Here is a link to it: https://www.waveshare.com/poe-hat-c.htm This seems to be sufficient for a regular few watts Power Amplifier. So ultimately the whole rig can be fed from a PoE switch...Making this even more minimalist configuration... I also added a slot for the SD card - I thought this could be handy. Enjoy the HAM radio... 73 es DX de Béla HA4BM
