PATRIOTWAVES PBD2. This model has been reconfigured and provides two radio receivers in one unit. It utilizes two TCXO (Temperature Compensated Crystal Oscillator ) Rafael Micro R820T2 (R860) chipsets circuit dongles.  The two RTL Realtek RTL2832U demodulation circuits offer superb performance in the emergency frequency ranges. 25Mhz to approximately 1750Mhz.  This unit is designed for use on Linux,  Windows XP, Vista, Win7, Win8 or Win10 OS's and includes phone support and online assistance.

The main focus of the PBD2 is for Police, Fire, Military and Emergency Frequencies can be monitored via this frequency range spectrum.  It can receive FM and other analog transmissions but also a variety of digital speech codecs such as APCO P25 Phase I and II, DMR motoTRBO, Provoice EDACS, NXDN, and X2-TDMA. These are the most common digital systems used by the government emergency, law enforcement and military communications.  The Free software programs available can work in AM, FM, LSB, USB, CW, ECSS and DRM modes.  This offers you the ability to add a simple inexpensive upconverter and receive additional lower band shortwave transmissions.

Since 911 FEMA has made an effort to consolidate and unify emergency services to a shared service known as Project 25.  The PBD2 offers two radios in one unit designed for monitoring and allowing the other to be used to hunt and find additional frequencies. While one unit is scanning found frequencies and transmissions, you are able to run another program on the same computer or laptop if it has the processing speed and minimum attributes. I have had 6 radios running on two computers. Having the PBD2 radio is a great emergency radio providing two radios in one unit. Great for use with DSDPlus, SDR Sharp, HDSDR and Unitrunker software which is available for free download. We provide phone and online support to get the software installed correctly.
