QCX 40m HELP #qcx
GREAT idea..... Wish I had thought of that.

Hello Mr. Ichikawa
A little hint about extension cables - if you are simply soldering flexible wires to the circuit board, use a hot glue gun to glue the wires to the board. That way the wires can't flex and break next to the board. The glue can be cut away if the circuit board needs repair in the wiring area.

It worked owing to it.
Cause:
Disconnection in extended cable.
Voltage was measured only on the main board, but it was not measured on the display side.
I was thinking too much that I could not understand simple things.
If you write here, you can become cool. It is very important to change your mood.
Many thanks.

"As the manual says the LCD display is not communicating with the processor."
Yes,I know it.
"A reliable check would be to put the processor into your 18 meters QCX."
Of course I did it.
Nothing started without any problems.
The voltage of IC is also measured, but it is almost the same as QCX 18 m.
The only difference is that the supply voltage is slightly different.
I understand that it is not communicating with the processor,
I can not find a bad place.
Double check the connection between the display and the processor.
I think that it is about there because it is extended.
Thanks.

When we made QCX 18m, we also sent hex and eep data from Hans - san due to a processor failure, so use itYoshi,

Either the processor is faulty or there is a bad connection between the two.

Thanks Alan-san.
For the processor, the data was contained.
I could also read it.

I am doing Upload again, but the state does not change. (Version 1.00 f)
I have a brand-new processor that does not contain anything.
The worst exchange is possible. Of course writing is also possible.

Hi
I made 40 meters of QCX. Last time, I made 18 meters, but I also had a hard time at that time.
But this time I feel more troublesome.
I confirmed all the troubleshooting of the square box, but no problem at all. I tried to rewrite the firmware,
but I was able to read and write without problem with the CPU on board.
I suspected the disconnection of Q5 and Q4, but there is no problem.
Is there any solution other than this?
