FSB (Frequency Sub Band) on MKRWAN1300 #21

I am pretty sure that the Murata module has AT command support for this, but it does not seem to be an available choice in the Arduino sketches. If I look at the MKRWAN.h library, it would seem to be lacking as well. This feature would allow most of us using US915 mode to select a sub band of 8 channels out of 64. Most mid-price gateways such as Multitech and Laird work this way. Thanks for the community support.

As a compromise, the hybrid choice gives the equivalent of FSB=1 i.e. uses the bottom 8 channels.

// Select your region (AS923, AU915, EU868, KR920, IN865, US915, US915_HYBRID) _lora_band region = US915_HYBRID;

Hi @almarion Can you please point me to where the channels are defined for the US915_HYBRID. By trial and error I have concluded that channels 0 - 7 are used. I have been unsuccessful in tracking down where its actually defined in the source code. I compared the region header files for the US915 and US915_HYBRID and they are the same.
