WINRADIO G303/313 FAQ

Q. Does the G303i have more demodulator options and higher performance than the G303e since the PCI interface is much faster than USB?

A. No, both have exactly the same options and performance. The required data transfer rate is much slower than available from USB, even with the 4-times IF over-sampling.

Q. You claim 0.05 microvolt MDS (minimum detectable signal) claim for the G313 receiver; how does this compare with the G303?

While both models are highly sensitive, the G313 is slightly better. Unlike the G303, the G313’s performance is entirely independent of the PC’s sound card.

Q. How do the G303 and G313 sample for audio?

A. The G303e uses the PC’s sound card to sample the 12kHz IF at 48 kHz. The G303i uses an internal ADC to sample the data which are then processed by the PC. The G313 series receivers use an internal ADC and built-in DSP, sampling the 16 kHz IF (variable from 12-16 kHz for DRM purposes) at 64 kHz.

Q. How open is the software for the WinRadio?  What language is it written in? 

A. Although we don’t publish the proprietary source code, we do publish a free programmer’s API (http://www.winradio.com/home/developer.htm). We also provide software application “plug-ins” using our “XRS” specification (http://xrs.winradio.com), and again, the "client" developer's license is also free. And finally, another free radio programming language in “Radio Basic” (RBASIC) is available at http://www.rbasic.com.

For those Linux users, we support some of our receivers as well; see http://www.linradio.com . (The G313 receiver will be added shortly).
