软件运行界面：
器材的参数（部分）：
frequency range from 9 khz to 1800 mhz (except cellular bands where required by law) （接收频率9khz到1.8ghz）
software-defined demodulation
extraordinary sensitivity
tracking front-end filters
excellent strong signal handling
real-time spectrum analyzer （实时频谱测试仪）
spot-on tuning in 1hz steps （频率步进1hz）
官方网站的测试结果：
usb接口的器材：
the receiver is extremely sensitive, making it possible to comfortably read cw signals under 0.05 µv input levels, yet featuring a respectable 95 db dynamic range making the receiver resistant to strong signal overload. the high sensitivity is also matched by that of the s-meter: the fully calibrated s-meter shows the received signal levels in dbm, µv or s-units, down to the ‑140 dbm noise floor.

看来，不论是软件的界面还是性能，这款器材不错啊！
记得好像国内也有老大们在开发，不知进展如何了啊？
