Hey all, as the title says, I am looking for a radio that can transmit in either one of those bands over about 1-2km, potentially low to no Line-of-sight. I have come up blank on places to find such a radio and was wondering if any of you guys could help me. This is my first time purchasing a radio like this, and I am communicating to it locally via RS-485, then broadcasting back to a base station, where the messages will be received, either by RS-485/ethernet/USB, and interpreted on a PC.

I am not tied to RS-485, but it makes sense for the bus I am creating on my system, so I thought to incorporate the radio into that system as well. Any suggestions/advice would be greatly appreciated. Thanks!
