I am not endorsing or backing this kickstarter yet, but I do want to keep an eye on it, and may make a small contribution. It looks Very interesting.
Basically, its an open source, handheld SDR. I think this is exactly the type of thing the HAM radio community needs more of. This device can demodulate and modulate the HF bands. It can’t transmit on its own. Hopefully, it will mature to be able to do so with future hardware revisions.
