The signal is very poor when I use headphone for ANT #14

Hi, I make a radio used your library with RDA5807 + STM32G030F6P6 + 128*64 LCD, it wroks. I'm very happy with it. But, I found the signal on the radio to be very poor when I use headphone for ANT. The signal is very good when I use other ANT.

Do you test with headphone for ANT? Is there any way to better with headphone for ANT?

Sorry, I'm a chinese and my English is very poor.

Hello. Thanks for your email and feedback. I have never used my prototypes with headphone. My main focus is the firmware. Please, check some functions available in my library that deal with audio. Specially, the setup the impedance of the audio output. For example setAudioOutputHighImpedance( true )

Think you for your answer. I made a signal amplification and interference filtering circuit myself，my radio with RDA5807 can receive abput 60 channels indoors now. It‘s very good.

Hi, care to share the schematic of the signal amplification and interferences filtering circuit?

Thanks in advance
