HRD-104 grey and black now had the 32.768 MHz crystal oscillator with wire on the center and 2 ground wires.
What will happened next? Less electromagnetic noise audio or bust?
Comment from 66vds translated from Russian: Yeah, they’re about on par. The noise squelch really ruins them. A station might still be perfectly intelligible, but the squelch decides there’s too much noise and clamps down on the audio. They shouldn't have done that. It’s a firmware issue.

The 200mm ferrite (twin coil) had installed already on Hanrongda HRD-104 (black)!
Has 45 turns on the left and 42 turns on the right or vice versa, the reception will be improved against the single coil on the HRD-104 (grey).

Revised shielding on the HanRongDa HRD-104:
Now it's on the DSP chip instead of covering both the MCU and the DSP chip (AKC6955)
HOWEVER after I went to empty lot again, the 576 kHz still plagued with noise. Not good! But still it worth a try.

The HanRongDa HRD-104 is arrived in gray!
Cost P419 from Shopee.
The ultimate replacement for Retekess V115 that I left in Cebu and retired to used it.
But there's a tradeoff, a smallest speaker could received a faint sound.
UPDATED: First is to have a modifcation like two AA batteries using battery holder to improve runtime since they used AAA battery instead of AA battery which hinders the battery runtime performance.
Soon EMI reduction and 200mm ferrite modification.
Nicknamed as Cute but Powerful and Tecsun PL-36X's cheapo beast
UPDATED: Another HRD-104 in black is also arrived! Cost P430 due to being discounted from Lazada. I am going to compared the two signals ala Gary de Bock.

Nokia 222
Cost P1490
Features
FM with RDS and Recorder (similar to previously tested Nokia 225)
2G/3G
Supports JAR files
External MicroSD Card
FM Radio Performance: It is very sensitive, I got Cebu FM Radio stations like XFM Cebu, Memories FM Cebu, Brigada News FM Cebu and so much more. Unlike other Nokia phones, this has FM Radio with RDS and FM recorder (same as Nokia 225 tested previously). However, it overloads the reception with lots of FM image frequencies on FM Band due to its oversensitivity, and if your too close of multiple FM transmitter. It is a best performer if your far away from multiple transmitters.
