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

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.

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 |
It's testing now, I will share it when testing end. |
