I am going to do the lottery tonight :) - 5 mins in and I have read AX5043 register values - so the journey starts....
Is it possible that you tested the boards you sent me with some other software?
See image and code below

#include <SPI.h>
uint8_t slaveSelectPin=10; // CS Chip Select
uint8_t regAddr;
uint8_t regVal;
void setup() {
digitalWrite(slaveSelectPin, HIGH);
pinMode(slaveSelectPin, OUTPUT); // set the SS pin as an output
SPI.begin(); // initialize the SPI library
SPI.beginTransaction(SPISettings(14000000, MSBFIRST, SPI_MODE0));
Serial.begin(9600);
}
void loop() {
digitalWrite(10, LOW); // set the SS pin to LOW
for (uint8_t regAddr = 1; regAddr <= 0x0F; regAddr++)
{
SPI.transfer(regAddr & 0x7F); // send address + r/w bit
regVal = SPI.transfer(0);
Serial.print(regAddr, HEX);
Serial.print(" - ");
Serial.print(regVal,HEX);
Serial.print(" - ");
Serial.println(regVal,BIN);
}
digitalWrite(10, HIGH); // set the SS pin HIGH
}
