You're in the path of a hurricane, and the eye just passed over your head. There is no electricity (apart from your own generator or battery), there is no mobile network and there is obviously no internet availability. But you do have a working computer with an SDR (20 MHz - 3 GHz) transmitter, Ham-it-up, a Wifi router, a mobile phone and an RPi3, and a few soldering skills.
- How can I transmit text, audio, images or videos to the outside world?
- What are the options available for this?
- What else is required to construct (or have) to do this? (In terms of antennas and hardware etc.)
First thought is that one should try to use an amateur satellite transmission, since that signal propagation would pass through least possible weather, i.e. straight up.
Second, that one should use some long wave TX that is less affected by local atmospheric conditions.
I was looking at this paper but it only cover VHF (240 MHz) and UHF (700 MHz), so I would imagine HF or LF would be a better choice.
I these days of hurricane season, I'd appreciate any practical or useful answers.
