15 year old High School sophomore noob here. We (crazily) are attempting to put up a CubeSat (shameless plug www.seakingspace.com). Using the Lora SX1268 433Mhz we tested the Semtech transceiver across the Catalina channel. 25+ Miles SF factors 7,9,11 at 125 BW. Worked great. We did a link budget and should work over 500KM line of sight no prob. The SX126X is the new improved version of the Lora chip. Im sure a verion with it will come out shortly.

LoRaWAN® distance world record broken. 766 km (476 miles) using 25mW transmission power. After almost 2 years, the world record of 702 km (436 miles) has been broken.Aug 14, 2019

25mW, imagine what you could do with 1/2 a watt.

SUPER COOL. It sounds like you are using similar SFs to us. Rock on!
