Modify Lora.c to allow use of 20dBm for those loud Americans cluttering up the spectrum.

Perhaps something like: // 20dBm **#define REG_PA_DAC 0x4D

define PA_DAC_20 0x87**

// transmit section of lora.c case RF98_MODE_TX: writeRegister(LoRaChannel, REG_LNA, LNA_OFF_GAIN); // TURN LNA OFF FOR TRANSMITT writeRegister(LoRaChannel, REG_PA_CONFIG, Config.LoRaDevices[LoRaChannel].Power); if (Config.LoRaDevices[LoRaChannel].Power == 0xFF) { // Turn on additional amp for 20dBm writeRegister(LoRaChannel, REG_PA_DAC, PA_DAC_20); }

I recently flew this and it made a huge difference. http://www.ncnearspace.org/missions/nsl-67
