@bjornhallberg said in RFM69 Range issues:
Gateway (rfm69hw) initialization:
#define MY_IS_RFM69HW
#define MY_RFM69_FREQUENCY RFM69_868MHZ
#define MY_RFM69_NEW_DRIVER
Maybe I missed someone pointing this out, but the original poster's gateway initialization looks like it's missing something. These defines are not at all obvious, especially with the HW version. Strange things can happen, including unexpectedly low power. Check the API docs and also another thread.
With the HW version of the RFM69 on the gateway, and the RFM69 new driver, in addition to what you list, you need to also include:
#define MY_RADIO_RFM69
#define MY_RFM69HW true
