Ham radio is too expensive, difficult, and power-hungry Initially I looked into ham radio, but it is just too expensive, difficult, and power-hungry to be practical. Then Alexander Yurtchenko told me about LoRa (Long Range) radio and Meshtastic, a cheap, low-power method of sending text messages across a few kilometers.
Don't really agree with this. Ham radio isn't this by def. There's a reason hamradio is part of national civil protection services ([[DARES – Dutch Amateur Radio Emergency Service]]) It does require ham licenses.
