"Excalibur", hmm?  So, does it only work if some guy named Arthur pulls a rock out of it?

Will be interesting to see how this stacks up against the Perseus.

Hmmm ... advantage Excalibur ...

Aside from the long, productive history of WinRadio -

A product of an Australian firm originally called "Rosetta Labs',
- later renamed to Radixon Group (http://www.radixon.com/) ("Advanced Communications and Monitoring for the Real World")
- which is a subsidiary of Robotron Group (http://en.wikipedia.org/wiki/Robotron_Group) (an Australian research & development and manufacturing company of various specialty high-technology equipment)

... 'WinRadio' produces a diverse line of products (http://www.winradio.com/home/products.htm) including some higher-tier receiver products like :

- Multi-channel Broadcast logger (http://www.winradio.com/home/ms8118-brl.htm)
- Mutichannel Monitoring and Logging (http://www.winradio.com/home/ms8118-g3.htm)
- Direction finding systems (http://www.winradio.com/home/df-systems.htm)

for the security and sigint (signals intelligence) markets, broadcasting and military markets (Note: this also means they have had a continuing revenue stream from which to continue product development as well as perform sustaining engineering on current product; important during production when 'problems' building hi-tech RF product is encountered) -

The Excalibur has a 16-bit 100 MS/s ADC (Analog to Digital Converter) versus -
The Perseus with a 14-bit 80 MS/s ADC for the Perseus

(Better/high resolution and slightly higher sample rate on the WR-G31DDC. In a way, this has more sampling horsepower/better resolution than the receive channels on the P4 WiMAX beam-forming base station we were developing at Cisco/BWBU/Navini)

And, the Excalibur costs less (from what I have seen in advertised prices).
