 ## Tracking Test!
-I've done several tracking test. The transmitter that I use was **Dorji DRA818V TX Shield** (more info, please visit [GitHub page](https://handiko.github.io/Dorji-TX-Shield/) or [repo](https://github.com/handiko/Dorji-TX-Shield)) outputing only **500mW (!)** (approx., might be less), powered from a 5V powerbank, **1/4 lambda wire antenna + 1 counterpoise**, inserted into my sling bag, and I brought it when I do evening ride. Best distance so far, I could hit the [YB0AZ](https://aprs.fi/info/a/YB0AZ) digipeater (only 4.5km, though).
