The spec sheet for the XBP09-DMUIT-156 radios says that there are 12 operating channels to choose from. However XCTU allows only 1 of 8 channels to be selected.
If the radio is within the ISM range of 902MHz to 928MHz, are the channels equidistant across that frequency range spanning the whole 26MHz, or are they so many KHz apart starting at a certain base frequency, much like the S3B radios?
What is the frequency for each of the 8 channels?
