Jeff Moore W1NC - QMX Rev. 1 Repair

 

The QMX Rev. 1 that I had assembled some time ago recently stopped working after making?many CW and SSB contacts with?the beta SSB firmware. By-the-way, the calibration went nicely. No issues there. It would turn on with no display but wouldn't turn off. Certain the CPU was dead, I was contemplating chucking it in the spare parts box and just continuing on with my QMX+.? However, I decided to send it to Jeff to?see if he could salvage?it, and I'm glad I did. Jeff discovered the CPU wasn't dead and was able to get it working again in perfect order. His turnaround?time and explanation of findings was great. If your QMX goes down I highly recommend Jeff to get it working great again. If it's beyond your repair capability, he's got the experience, tools, test equipment, parts and talent to make it happen. Thanks again Jeff.

I totally agree. I have a Rev. 1 QMZ+ that I built recently. It had the misfortune of having one of the non-functional 1804 chips. I tried to replace myself, but made a mess of it. I sent it off to Jeff and he did a detailed analysis, a meticulous repair and then did a thorough check on the unit.
I finally had time to go out for a POTA with the device and it performed magnificently. Thank you so much Jeff for your wizardry!
