Hi Gerard,
It is used in the ubitx_si5351.ino, see extract below.
It is set at 8mA for ubitx V5 so at the right value.?
I tested this setting on a V3 which defaults to 2mA and it improved the Rx and Tx so I believe it should always be set at 8mA regardless of the model.

#if UBITX_BOARD_VERSION == 5
uint8_t? si5351bx_drive[3] = {3, 3, 3}; // 0=2ma 1=4ma 2=6ma 3=8ma for CLK 0,1,2
#else
uint8_t? si5351bx_drive[3] = {1, 1, 1}; // 0=2ma 1=4ma 2=6ma 3=8ma for CLK 0,1,2
#endif
