I wonder if 2 way satellite comms is just as effective as this old technique. The satellite sends mircowaves over a large area so isn't giving a location away.

  Difficult to transport, high power usage and requires a specific view of the sky. SW radios can be acquired easily most anywhere. It’s just your vintage set that’s usually tuned to the local music station.

    The reason satellites aren't used is their location is known, and because of this they are easily jammed or listened to. I'm not sure that the reasons you gave are really valid, especially for reception. > Difficult to transport I transmit to low earth satellites each weekend using a hand held radio that fits in a jeans pocket. > high power usage I use about 5w. > radios can be acquired easily most anywhere You can easily buy a radio that can do this for $20 on Amazon. I don't need a specific view of the sky on passes where the satellite is high enough in the sky, which happens one or two times a day.

  Satphones are illegal or heavily restricted in a lot of the places where spies might want to operate. https://www.outfittersatellite.com/Countries-with-Satellite-Phone-Restrictions_b_11.html https://www.outfittersatellite.com/Countries-with-Satellite-...
