Hi Joel, congratulations for your work.
I bought 2 devices.
Why not use the 3 LEDs to have a better understanding of the operation of the device?!
Also use a led to indicate signal reception as a "tester"
Example:
LED 1 = Power on signal (As now) :)
LED 2 = On when receiving signal / Flashing if signal in log memory.
LED 3 = On steady or flashing when transmitting a signal.
Thanks for your attention.
