Todo:

Julian -> double check these values please.

Test:

Test that we can receive LoRa transmissions from the satellite with these default parameters

(ID CONF_LORA_RADIO_T1) (SEV 1) Check that the radio transmits at LORA_BANDWIDTH.

(ID CONF_LORA_RADIO_T2) (SEV 1) Check that the radio is transmitting at LORA_SPREADING_FACTOR.

(ID CONF_LORA_RADIO_T3) (SEV 1) Check that the radio can/is transmitting at LORA_SPREADING_FACTOR_ALT.

(ID CONF_LORA_RADIO_T4) (SEV 1) Check that the radio is transmitting at LORA_CODING_RATE.

(ID CONF_LORA_RADIO_T5) (SEV 1) Check that the radio is transmitting at LORA_OUTPUT_POWER.

(ID CONF_LORA_RADIO_T6) (SEV 1) Check that the radio draws no more than 160.0mA.

Test:

(ID CONF_LORA_RADIO_T0) (SEV 1) Check that the radio transmits lora at LORA_CARRIER_FREQUENCY.
