I have started experimenting with ESE ESD UHF communications.

Anyone else out there doing likewise?

Sorry,  I'm not familiar with the term.  Can you provide more info?

Earth-Saturn-Earth Huh

Derek, could you provide a little more clarification on the terms? Some of us are unfamiliar..  Cool

I've dabbled in EME.. working on ver 2.0.. but not familiar with ESE or ESD

Earth-Sun-Earth?  I doubt it, the sun is a big ball of electromagnetic radiation, some at RF.  But only a small fraction, but even that would be way bigger than our puny kilowatt.  The sun is easy to find, though...   Grin

ESE as (Earth-Satellite-Earth) might be fun. The challenge would be the very small amount of reflected signal that would come back to a receiving site after bouncing off of the small area of a satellite. This is very similar to RADAR operations but those systems use very large dishes for high gain on the link path and ridiculous amounts of ERP (effective radiated power) to work.

I do not know how many large LEO (low earth orbiting) satellites are up there that you could get a satisfactory bounce off of (the polar orbiting weather sats that transmit around 137 MHz would be one example where the orbital elements are well known). You could try to bounce off of those as they usually do two swings over the same area at least twice a day.

It is believed by the people involved that the recent Transatlantic reception of a 2m signal was because of a reflection off the ISS.
