To Reproduce

radio.begin(434.53, 500.0, 11, 7, '\022', 10, 8, 0);

You're right, LLCC68 is missing a dedicated begin, so it's actually calling SX1262::begin, which is the reason why the range checks fail.

I added the missing method, so it should be fixed now.

setBandwidth should be ahead of setSpreadingFactor, or it will exit with -9. @jgromes

You'Re right, that's indeed the case when using non-default parameters for begin(). It should be be fixed now.
