Radio amateur Jan van Muijlwijk PA3FXB along with Tammo Jan Dijkema and Frank Zeppenfeldt successfully sent an amateur radio 430 MHz band LoRa message to the Moon and back

They used a Semtech LR1110 RF LoRa transceiver chip feeding a 350 watt amplifier which in turn was fed into the 25m dish antenna at the Dwingeloo radio telescope. One of the messages even contained a full LoRaWAN frame.

The Dwingeloo radio telescope, operated by the CAMRAS foundation, has a history of being used in amateur radio experiments and is now often used for Moon bounces, but this was the first time a data message was bounced using a small RF chip.
