It was intersting to read that part of the design will be locked down, to meet FCC requirements. The celluar band lock out has never been a requirement in many countries, such as here in New Zealand. While I dont care about those bands I do wonder if it will lock out out other non-amature band uses in the name of FCC compliance, that we don't need?
For example us hams who are also like 4WD outings find that some UHF ham rigs can serve a dual role as a UHF CB, saving one extra transciever in the vehicle. In that case we are transmitting at 477MHz with a 5W limit, which while legal here would be illegal in the USA. Actully we have the reverse problem, imports from China on the USA FRS/GMRS channel being offered localy dispite being commerical frequencies here. Also it's nice to be abe to listern to commerical channels. The cheap Boefeng is great in a vehicle as it can replace 5 other radios (2M, 70cm, UHF CB, Marine and a scanner). That may not be a big deal if you have a huge Jeep but we typically use smaller 4WD such as the Suzuki Jinmy were 2 transceivers as about all you can fit.
I think an SDR such as this would be great in such an enviroment, if it could get down to 26MHz it could replace the NZ and USA HF CB rig as well allowing one box to do everything, feed it to the car stereo aux input and control it with the same Android tablet used for naviagation. It would make the ultimate communictions solution for a smaller vehicle. I really like the possiblities it opens for new modes or just embeddeding a bit of digital data in the current modes, such as the location of the transmitting station and a call sign etc.
Even as currently defined it seems like a great peice of gear, hope it goes well for Bruce.
