Bob,
Looking at the lastest code I see two places, which is one to many, where the transmit power level is set.
They are:
ax5043-ax25.c Lines 435-436
TxTask.c Line 63 calls radio_set_power() at line 112
They both set the power level to 0x0020 which is very weak.
I don’t see a place that sets the transmit level to 0x0d.
Let me know where you found that reference.
I would suggest setting both places to 0x0FFF for maximum output (+15 dbm)
