Winradio WR-1550e $549
Sensitivity is poor in LF range.
This is an external version of WR-1550i with an identical receiver and software, contained in an elegant
enclosure with RS-232 interface (PCMCIA Adapter optional). Very suitable for cost-effective VHF/UHF
monitoring applications in conjunction with portable computers.
This is a medium-range external receiver similar to its popular predecessor WR-1500e with improved dynamic
range, spurious signal rejection and selectivity. The frequency range is 150 kHz to 1.5 GHz (the US version
excludes cellular frequencies 825-849 and 869-894 MHz).

Winradio WR-3150i-DSP $1375
The WiNRADiO WR-3150i-DSP receiver supersedes the highly successful WR-3100i-DSP model, introducing
improved spurious signal rejection,selectivity and other hardware and software improvements. The
WR-3150i-DSP receiver puts advanced radio receiver technology directly on a personal computer platform, to
create a complete spectrum surveillance system. This receiver is intended for government, military, security,
surveillance, media monitoring and industrial applications. The frequency range is 150 kHz to 1.5 GHz (for
non-government customers in USA, cellular frequencies 825-849 and 869-894 MHz are excluded). The ISA
card plugs into the motherboard of an IBM-compatible PC. An in-built DSP is used for audio recording and
