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).

It works as described. The sound in the headphones is loud enough and clear. The hardware receiver is without reservations. Software v 1.01 has a flaw in receiving LW and probably in the other AM ranges: there is an interference in the form of a squeal that disappears when the antenna ground (the nut of the SMA connector) is touched with a finger.
