Using a frame antenna to listen to MW stations with the ATS-20+ in a hostile environment for listening (close to elevators and transmission lines, among other sources of noise). The frame antenna is very easy to build: 7 or 8 turns of a wire (diameter 1,3 mm) in a 12cm x 10cm frame; and a BNC adapter to connect the antenna to the ATS-20+

nice work👍

SIM800C Library and PU2CLR RDA5807 library do not work at the same time I want to make FM radio controlled using SIM800C module, but when I add the radio library, I cannot receive data

@ramazanayten3758 Год назад

#include RDA5807 radio; When you make this library passive in the project, internet data comes by using the SIM800C Module, when you make the radio library active, the data does not come, affecting the internet connection.

Is there a noise canceling soft mute?

@pu2clr Год назад

Yes. This receiver has Softmute function. You can enable or disable that. It is based on SI4732/SI4735.

@@pu2clr Can the noise canceling be completely muted instead of softened?

@pu2clr Год назад

@@ramazanayten3758 I'm not sure I understood your question. I don't think so. You can mitigate the noise by selecting the appropriate filter. This receiver has 1.8, 2, 2.5, 4 and 6 kHz bandwidth on AM mode.

@@pu2clr I'm using the RDA5807 FM Module, I'm using the soft mute feature in your example library on github

@pu2clr Год назад

@@ramazanayten3758 I see. The SI373X family has the same functionality on AM and FM modes.

Сделайте антенну резонансной. Успехов.📻🌎👍

@pu2clr Год назад

Existe um circuito interno no SI4732 que faz a sintonia automática da antena(um capacitor variável controlado pelo sistema) . Portanto, o sistema já é, de alguma forma, ressonante.
