Still used nowadays: airplane reflections are being used by ham radio dudes. There's a software around that even calculates the optimal reflection parameters based on ADS-B aggregators.
Thanks too relatively modern digital modes this doesn't need too much transmission power.
On the upper GHz bands with dishes they even manage to do reliable FM chats. But that requires a lot of gain and active steering of the dish.
- Phithagoras 1y agoSounds like fun! Do you remember the name of the software?
- SuperMouse 1y agoMost likely it's FT8 or a more modern mode.
- K0balt 1y agoIdk if it works with more modern bands, but back in the GSM days I used to make calls in out-of-service areas when jets flew overhead.
- SuperMouse 1y agoGSM is a bit limited because of its Timing Adance (TA) field. It should max out at 32km.
- K0balt 1y agoHas it always been set to that? I’m pretty sure that I have connected line of sight to cell sites at much longer ranges than that. Or maybe I’m remembering an old pre-gsm TDMA phone?
