AFEDRI Receivers

A new Stand-Alone Touch Screen SDR

Alexander Trushkin (4Z5LV) develops and produces SDR receivers since 2012
His receivers are available in different setups:

  • standalone for remote control -or- with touch screen display (1 RX Version only)
  • HF -or- HF-VHF-UHF
  • 1, 2 or 4 RX
  • in box -or- assembled PCB only
  • SMA -or- BNC connectors

Compared to some other receivers, the device is equipped with a LAN and USB interface. This provides full flexibility when the RX is integrated into a system.

The LAN-IQ receiver is an extended version of the AFEDRI SDR-NET, which is a Black-Box only receiver.
The LAN-IQ becomes a stand-alone receiver with the extension (touch screen, headphone output) contained in the same housing.

The SDR-NET can only be operated via the computer.
