Etherkit JTEncode

Generate JT65, JT9, JT4, WSPR, and FSQ symbols on your Arduino.

Library Type

This library very simply generates a set of channel symbols for JT65, JT9, JT4, or WSPR based on the user providing a properly formatted Type 6 message for JT65, JT9, or JT4 (which is 13 valid characters) or a callsign, Maidenhead grid locator, and power output for WSPR. It will also generate an arbitrary FSQ message of up to 200 characters in both directed and non-directed format. When paired with a synthesizer that can output frequencies in fine, phase-continuous tuning steps (such as the Si5351), then a beacon or telemetry transmitter can be created which can change the transmitted characters as needed from the Arduino.
