SDR Play

The SDRplay RSP is a powerful wideband full-featured Software Defined Receiver which covers all frequencies from 100kHz up to 2 GHz. All it needs is a PC (Supported Platforms: Windows, Linux, Mac, Raspberry Pi 2 & Android) along with an appropriate antenna to provide excellent communications receiver functionality. Combined that with the power of readily available SDR receiver software and you are on your way to enjoy all modes of operation while monitoring up to 8MHz of spectrum at a time.
What's really exciting is that SDRplay offers an open API, allowing developers to create new demodulators or applications around the platform.
Amateur Radio Operators will enjoy all modes of operation for the Ham Bands ranging from experimental LF, through all the HF bands, VHF, UHF and up to the 23cm band.
With the SRDplay RSP general coverage receiver, you can enjoy exploring the rest of the RF spectrum as well!
Key Features:

  • Robust and strong plastic case

Review / Observations

Initially, I am very impressed with the SDR Play !

For LF /HF reception I used the Alpha Delta DX-EE Antenna       

For VHF/UHF reception I used the A² Engineering Discone  Antenna   

And the  cable of choice Times Microwave LMR-400

Using HDSDR software was my first choice mostly because of ignorance.
That being said, I have installed SDR Sharp and I will be experimenting with that. From what I can tell this platform seems to be more versatile because it has plug-ins available like PL/DPL Decoder along with with other options.
