Important Tips:
1. Headphones are not included in the shipping list. The headphones shown in the picture are only for demonstrating the FM antenna function. Please provide your own headphones!
2. If you choose the CNC metal casing version, the CNC aluminum alloy material has a certain shielding effect on radio electromagnetic signals. While improving reception performance, it can also weaken the Wi-Fi signal strength. Please be aware of this before purchasing.
V4 Upgrade Contents:
1. The Si4732 receiver section has been shielded to suppress electromagnetic interference; an ESD protection chip has been added to the antenna input.
2. The Hi-Z circuit has been moved to the front end of the antenna path and uses a more stable VCC_RADIO power supply to preserve signal resonance and reduce noise.
3. Added the function of using wired headphones as an FM antenna (requires a strong FM signal and a relatively long headphone cable for optimal performance).
4. The left and right channels have been swapped; amplifier and speaker parameters have been readjusted to improve sound quality.
5. Replaced with more expensive and superior components: a more sturdy and solid telescopic antenna, and a better-feeling, non-slip knob cap.
