“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 PC.
The receiver channel:
- Orange Pi One Plus https://fr.aliexpress.com/item/32849314381.html?spm=a2g0s.9042311.0.0.27426c37uU0xuI
- Hack RF + TCXO + Aluminium Case or a simple RTL-SDR key https://fr.aliexpress.com/item/32889992261.html?spm=a2g0s.9042311.0.0.27426c37K6o1eL
- Bias-T https://fr.aliexpress.com/item/32968784911.html?spm=a2g0s.9042311.0.0.27426c37YwnIa3
The transmitter channel:
- 2 amplifiers SPF5189 https://fr.aliexpress.com/item/33020566028.html?spm=a2g0s.9042311.0.0.27426c37uU0xuI
- Orange Pi One Plus https://fr.aliexpress.com/item/32849314381.html?spm=a2g0s.9042311.0.0.27426c37uU0xuI
- Hack RF + TCXO+ Aluminium Case https://fr.aliexpress.com/item/32889992261.html?spm=a2g0s.9042311.0.0.27426c37K6o1eL
- Band-Pass Filter 2.4 GHz https://fr.aliexpress.com/item/4000082571769.html?spm=a2g0s.9042311.0.0.27426c37K6o1eL
- WIFI amplifier https://fr.aliexpress.com/item/4000216879545.html?spm=a2g0s.9042311.0.0.27426c37K6o1eL
For transmission security, the amplifiers are supplied with 12v and 5v only when audio frames are received by the Orange PI from the web browser. The diagram proposed here:
