So I looked into this a bit more. In the RFD manual they claim to be EU complaint and give the following configuration details.
Frequency range: 869.525MHz - 869.85MHz (not matching the spec but maybe there is a typo or offset…)
Number of channels: 2
They also have some footnotes saying that there might be some additional parameters which are locked. Would be interesting to know which ones and what value they should be. The radio I have was bought long ago and not EU locked. I thought I could try to flash the latest firmware, set it to EU and read back the parameters to find out. Will try that next week.
The above parameters then looks in general okay, I am just not sure about the number of channels. From the regulation it seems that if the channel is greater or equal to 100kHz (which I guess it would be) then we need at minimum 47 channels. This is just my interpretation, I could be completely wrong.
Does anybody else know how to properly interpret this?
In the previously posted spectrum plot the channels look very wide. Could be that it used a larger frequency deviation to improve performance and maybe this is another parameter they changed (lowered) when in EU mode.
