Hello from Washington State. I have experimented with software defined radios for quite a while and work as a test technician at a communications company here in the Seattle area.
I just recently read about Outernet as well. I ordered a week ago. I'm pleased to report that I just received my Dreamcatcher, the Passive Patch Antenna and an SDRx board this evening. My first goal is to evaluate the basic systems and outdoor packaging of the antennas.
I will be building two systems.
1) Dreamcatcher and the passive patch antenna.
2) A home-brew turnstile antenna, an NooElect LNA, a Mini-circuits bias tee, the SDRx board and a Raspberry Pi running the legacy SDcard.img image.
Your system is a little different from these two. It's my understanding that the Dreamcatcher board already has an L-band SAW filter (1525 - 1559 MHz) and a Two-stage L-band LNA with 34dB gain built in. To prevent overloading your Dreamcatcher board, we'll have to disable the SAW filter and the LNA.
I will be happy to help you when yours comes in the mail.
