Re: QCX-mini Blown IC?

 

Hi Scott. That usually happens when you install a blank IC2 without the EEPROM file loaded. I suspect something happened to IC2 when it was shorted. The easiest fix is to order a new firmware chip from Hans. Maybe your?Dad could add that to the order for the new rig. Doesn't hurt to have another one. If not too late he could change the order for the new one to be on a different band.

I see you said QCX Mini in the title and QMX Mini in the note but fortunately the picture is of a QCX Mini. Good luck

Hi all,?
My Dad just finished his QMX-mini build and after adjustments,(before casing) accidentally laid it on a spiral notebook and shorted something out. Now he gets the message ¡°Use original IC¡±.?

The only reference to this in the groups is from 2017 where someone tripped a protection fuse in an IC and needed to update firmware I think. Any idea if this is a simple fix? Is it a hardware, software or both issue? This is the 20M version that uses IC2 AT mega328. Is the IC2 likely the culprit? Dad ordered another kit thinking it¡¯s all fried but I suspect it can be a somewhat easy fix if we can trace down the issue.?

thanks all,
Scott
