I had several email exchanges with Zac earlier in the year when the call went out for Amateur involvement. I was trying to get enough information to attempt to put together a hardware decoder for the spread spectrum signal. The Cornell team seemed only interested in having hams send in data files of broadband collections from a USRP radio. While these receivers are very common in educational and commercial labs, they are not that common in ham shacks. In my opinion, if the Cornell team wants to generate interest inside the ham community, they need better information on the typical capabilities of the average operator. The greater the appeal, the more support they will get. HowieAB2S
