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 ("Advanced Communications and Monitoring for the Real World")
- which is a subsidiary of Robotron Group (an Australian research & development and manufacturing company of various specialty high-technology equipment)

... 'WinRadio' produces a diverse line of products including some higher-tier receiver products like :

- Multi-channel Broadcast logger
- Mutichannel Monitoring and Logging
- Direction finding systems

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).
