#QCX Broken ATmefa328P and data #qcx

 

Damaged ATmega 328P
QCX T / R 18 MHz type was made, but it does not work.
Only square boxes are out in the first row.
Troubleshooting saw the same phenomenon, ATmega 328P is not inserted or it is not working properly. Is the IC pin bent? But none of them were applicable.
Finally there is a possibility that ATmega 328P is broken. There is and download data from this failed ATmega 328P. (It was possible to some extent, but the size of eep is too small? Size=2.891KB)
Uploading the downloaded data to the new ATmega 328P launched the radio.

Unfortunately, I found out that it did not become a setting screen.
 Pressing the button on the left side for a long time on the setting

screen returns to the original state.
It seems that eep data is broken. Is this data only?
I think that it is probably because the original ATmega 328P data could not be read to the end.

There is a known issue where some defective processors were accidentally shipped.? Contact Hans @ QRPLabs and, if that is in fact your problem, he will get you fixed up.
 

okay, I will contact you.
Thank you.
 

Oh, contact?him not contact you. :-)
Sorry.
 

By the way, there are 10m/12m in BAND select, but can not you use this?
Of course it is after designing and changing the LPF.

Afterwards, as usual, when you turn on the power, it remains box display.
However, pressing the tuning knob a long time came to start.
But I think that this is not the original specification.
Although I displayed Band Select, I set it to 17 m by turning the tuning knob and can not set it even by pressing Select button.
If you turn off the power without setting it, it becomes 0.000.00 MHz.
I can not return to the initial state because (7.8 Factory rst) on the setting screen can not be displayed.
.

Please help me.
 

Yoshi-san, really nice job with the enclosure, that looks awesome!
