I'm looking for some guidance to tweak the US frequencies on the Things Node so I can use it to test my gateway deployments.
The TTN US-915 frequencies are defined like this [1]. My gateways are using this frequency plan [2]. Could some one provide guidance on how I can program the Things Node to support plan [2]?
