> <https://github.com/matthijskooijman/arduino-lmic/blob/master/src/lmic/lmic.c>

has the same bug:

void LMIC\_disableChannel (u1\_t channel) {  
if( channel \< 72+MAX\_XCHANNELS )  
LMIC.channelMap[channel/4] &= ~(1\<\<(channel&0xF));  
}

That 4 should be a 16 to get the right byte of the array - only affects CFG\_us915.
