Red Pitaya for Radio Amateurs

SDR is a great tool for experimentation and the development of new communication protocols with the ability to alter modulation methods, operating frequency and other attributes without additional hardware costs.

What makes SDRlab the perfect tool for SDR?

If you are looking to get into Software Defined Radio, look no further than SDRlab which was developed specifically with this use in mind. It comes with two 16 bit ADCs, 50-ohm inputs and 14-bit DACs, 50-ohm outputs. It uses dual-core ARM Cortex A9 offering massively better performance, the Xilinx Zynq 7020 FPGA for real-time processing capabilities plus an ultra-low phase noise 122.88MHz clock which makes it more hardware-compatible with HPSDR. RF inputs are optimized for minimal distortion, noise and crosstalk which significantly improves reception and broadens the choice of antenna

What can you do with SDRlab?

  • Mobile communications: Due to its flexibility, software-defined radios are more and more popular solutions in areas such as mobile communications. Instead of changing hardware, changes to standards, protocols even at the waveform level can be purely done by upgrading the software. Since software upgrade can be even done remotely, not only brings system upgrade savings of cost but also saving on costs of system maintenance.
  • Research & development: The software-defined radio can be useful in many research projects since it is a very versatile solution that can be easily adjusted to receiver and transmitter requirements without the need for hardware redesign.
  • Military: Due to its flexibility software-defined radio became popular also in military telecommunications, providing secure and reliable communications.
  • Amateur radio: Radio hams SDR community is very strong since it is a perfect fit product for HAM radio communication needs.
  • Other: Due to its flexibility, SDR also found its use in other applications that require signal generation or acquisition and signal processing. (e.g. Radio astronomy)

Using the Red Pitaya SDRlab in the Reverse beacon network

The Red Pitaya SDRlab 122.88-16 (which I will call the RP-16 from here on out) reflects the company’s recognition of the needs of radio amateurs, and particularly those who are interested in contributing to the RBN.
