WINRADIO WR-G305e
Špičkový SDR přijímač 9kHz-1800MHz,
-----
The WiNRADiO G-305e was invented at the Ham Radio 2006 and was developed for the ambitious
shortwave listener and professional users as well. The G305 belongs to the generation of
Software-definied Radios (SDR), as demodulation and decoding of wireless signals
is done exclusively by software. This allows a more precise signal processing and a more flexible
and cost-saving way of updating for future analogue and digital modes like DRM.
G-305 window with FMW-Option
Frequency coverage is 9 kHz - 1800 MHz (optional up to 3500 MHz), with a tuning resolution
of 1 Hz. The supplied extensive software offers real-time display of the IF-spectrum
adjustable IF-bandwidth (100 Hz, 15000 Hz in 1 Hz steps), search functions with
unlimited frequency storing, HF-Spectrum analysis, switchable preamplifier(+12dB)
and attenuator (-18dB), as well as various squelch functions (Signal level, noise,
voice, CTCSS and DCS).
Prof. Demodulator & Virtual Soundcard VSC
The Professional Demodulator Option of the G305 allows to set important parameters,
like the bandwidth, which is adjustable in 1 Hz steps.
The Virtual Soundcard VSC at the WR-G305 offers an additional virtual soundcard and
expands the application possibilities, but at the same timer avoids problems that may
happen when using the PC-Soundcard. Differences in sampling rates between the
Winradio-Receiver and the PC-Soundcard are compensated. Difficulties because of
buffer overrun or underrun are avoided this way.
Signal loss due to the dual conversion processes (digital to analog and at ther PC-
Soundcard analogue to digital) are a thing of the past. Furthermore signal processing
becomes faster, and the processor load is reduced. The PC can work more fluently.
External demodulation software has more soundcard power available.
