Logging Ham Radio repeater usage with a Baofeng and Adafruit IO #HamSunday
"The Austin N5OAK Ham Radio Club Repeater seems to be pretty active. That shouldn’t surprise us much because the club has a lot of activities and a lot of enthusiastic members. Still, we wondered just how active and opened the spare parts drawer to see if it held a solution."
"Turns out the spare parts drawer did; take a look at the wiring diagram at the top of the page. We simply used an Espressif ESP32-C3 Dev Board with an input pin wired to to the output speaker of a Baofeng HT tuned to the repeater frequency. We monitor the C3 input pin and if it sees a signal the repeater in transmitting. We push that data to Adafruit IO at the top of each hour to graph the history."
