...The beacon transmits a user configurable, identification string, in Morse code at 12 WPM, followed by a 10-second carrier and 20-second pause cycle. It operates at ~10 mW, offering several hours of runtime on an 800 mAh battery. The firmware allows full parameterisation in code, including operating frequency, CW speed, transmit message, carrier duration, pause interval, and RF output power adjustable from -9 dBm to +21 dBm (0.12 mW–125 mW). A programmable button enables TX disable and deep sleep mode.
