I have a RAK7246 EU868 on my shelf and revisiting the docs it’s not totally clear if the concentrator is fixed or tuned to different regions or if it can cope across a range.
I’d really like to quickly test US915 with a Murata module. I know the antenna tuning will be out, it’s more about ensuring the firmware on the module is co-operating.
I’ve taken the unit apart and I’ve seen the traditional resistor next to the EU868 label, but as I say, the data sheet sort of implies that the module may be able to cover a wider range.
So, question, is this likely to work?
If not, if I buy some US915 gateways, will they work with AU915? And do these run to AU923?
Before anyone worries about my legal liabilities, I do have a big tin box with some high quality tight chain link to try this out in and I can dial down the power so I don’t think I’ll be in harms way with testing.
