    This is a receiver for people that likes to have fun, an at the same time they can learn a lot about coding as you can change and update the receiver firmware if you want. I bought this small receiver to learn how to program the ESP-32 microcontroller.
    At the same time I got a very sensitive all-band receiver.

    Działa tak jak opisano. Dźwięk w słuchawkach jest wystarczająco głośny i wyraźny. Odbiornik sprzętowo jest bez zastrzeżeń. Oprogramowanie v 1.01 ma wadę przy odbiorze LW i zapewne w pozostałych zakresach AM: występuje zakłócenie w postaci piszczenia, które zanika po dotknięciu palcem masy anteny (nakrętki wtyku SMA).
