It's good to come up with this and I fully agree that we should respect the regulations. You explained it well by the 'stealing' analogy.
I think the links you've inserted are good, but they provide an awfull lot of information which most probably is not all applicable for our mySensors users. Would it be an option to elaborate what the limits are for us in e.g. using the nrf24L01+ antenna's?
I'm using 3 nrf24L01+PA+LNA SMA Antennas (amplified) as well as approx. 15 small nrf24L01+ modules in my network. I'm wondering am I still acting within the regulations if I use an amplified nrf24L01+ LNA etc. in max power mode (NRF_PA_MAX) using Channel 24?
I would really appreciate it if you can tell me if I comply with the regulations.
