WINRADIO WR-G303I RX 9KHZ-30MHZ CARD
WINRADIO WR-G303I RX 9KHZ-30MHZ CARD
Description
-
This award-winning low-cost receiver continues in the fine tradition established by WiNRADiO's successful range of wide-band PC-based receivers. The "G3" stands for "the third generation": As the original, award-winning, first-generation WR-1000i receiver was the world's first commercially available wide-band receiver on a PC card when launched years ago, the newly introduced WR-G303i is the world's first dedicated shortwave receiver on a PC (PCI bus) card. The WR-G303i receiver is also the first commercially available receiver where the entire final intermediate frequency stage and an all-mode demodulator are entirely executed in software, running on a personal computer. The WiNRADiO G303i: A ground-breaking shortwave receiver that will surely amaze you.

The Professional Demodulator offers two additional demodulation modes, DSB and ISB. 2. The Professional Demodulator offers continuously adjustable IF bandwidth from 1 to 15000 Hz. 3. The AM sensitivity is specified at 30% modulation for 10 dB S/N ratio. For 80% modulation, typical AM sensitivity of WR-G303i is 0.3 µV in 2-30 MHz range. The Professional Demodulator improves sensitivity further by making it posible to extend filter lengths, and adjust the IF bandwidth for optimum reception of the received signal: This results in a typical improvement by 2-3 dB on AM/SSB/FM and up to 10 dB on CW.
