Remote SDR V1- Purchase

“Remote SDR” is a web application for remotely controlling an Ham radio transceiver between 1 MHz and 6 GHZ. Below is the list of the main supplies of equipment to be made, excluding antennas and PCs, as part of an application to the QO-100 satellite. Purchases are made directly in China from Aliexpress, it works very well. It takes 2-3 weeks to deliver.

The receiver channel:

• Orange Pi One Plus https://fr.aliexpress.com/item/32849314381.html?spm=a2g0s.9042311.0.0.27426c37uU0xuI
  Note: it seems that as of this day (July 2021), the Orange pi One Plus is no longer on sale. On the other hand, the Orange Pi Zero 2 remains available.
• or Orange Pi Zero 2, 1GB of memory
