4 and 8 Watt WiFi bi-directional amplifiers are designed for about 10-20 dBm input power. They listening in their input for a relatively strong signal to decide whether turn over to TX state from RX state (and changing over RF switches). Doing this simply rectifying the inrush RF power and leading that into an amplifier Read more about Modifying EDUP EP-AB007 4W bi-directional Wifi amplifier for OA-100 Es’hail satellite operation, non-stop TX mode[…]

Receiving WSPR With An RTL-SDR V3 Dongle

The V3 version RTL-SDR blog dongle is perfectly fits for WSPR reception as per my tests. As it has internal switches it uses only one SMA connector for HF (500kHz to 24 MHz) and UHF operation, no need for changing connectors for direct sampling mode. This makes the RTL-SDR V3 dongle really convenient and easy Read more about Receiving WSPR With An RTL-SDR V3 Dongle[…]
