Why does Flipper restrict US bands to the following (per the Flipper device Region screen), which excludes 390 Mhz, when US devices like my garage door opener, are legally transmitting on 390 MHz? It seems that prevents Flipper from acting as my garage door opener, though I’ve had the Flipper for an hour so very new to it.
Region: US, bands:
304 - 322 MHz
433 - 435 MHz
915 - 928 MHz
Is there a way to add the 390 MHz to unblock this?
