New module’s replaced old one. The 6.2 module introduced 3db receiving sensitivity improvements and less harmonics comparing to version 1.1.
This is raw RSSI value report by LoRa modem, using lowest possible TX power less then 23dBm (less then 250mW), and non directional antennas.
Finally I found time to test it.
Months ago i started to develop custom firmware for cheap 1W LORA module, to use it as LRS RX/RX devices. Now it’s almost ready for testing 🙂
