A bizarre manipulation of the sending spell, used to broadcast an unlimited ASV-based audio output across long distances. This output can be picked up by a Sendo Receiver (Normally just called a “Sendo”). There are several types of Sendo Broadcast Signals:
KS - KS or Kinetec Sending requires the runes broadcasting the message to be spun rapidly in a turbine. This physically “throws” the signals out into the world to be received. It has many opportunities for system failure, and gets a limited range, but has a much cheaper startup and operation cost. This is your Grandpa’s Radio.
SRS- SRS or Self-Regulating Sending, uses modern ASV technologies to amplify the broadcast signal at a much longer range, without any need for spinning it really fast! It requires a much more sophisticated, expensive station and has much, much higher SPRK requirements.
LS- Lonely Sending is much closer to the traditional sending spell. They are the most expensive signals to send, and their uses are so limited they are almost exclusively used to build private, powerful information networks.One Broadcaster, One Receiver.
