The first gateway in Bucharest is up. HOORAY!
We purchased a couple of Multitech MTAC 868 LoRa boards and a couple of USB to Mini-PCIe converters.
Then Adrian Lita hooked each MTAC to a Raspberry Pi. Silviu Panaite successfully installed the software, as explained in Nestor Ayuso's tutorial and voilà!
See the Bucharest DIY #1 gateway alive and kicking!
Bucharest DIY #2 coming up soon!
