Received my QMX mid band yesterday and half of the box was crushed during shipping. The only "damage" ,if you would call it that, I originally saw was that one of the boards was already separated from the other so no biggie. Now I am starting the build and upon closer inspection of the main board I see all 3 of the "331" I believe inductors have the tops shattered. I remember reading, maybe on the qrp website, that if these were cracked you could glue them back assuming the wire was still intact. Problem is the missing chunks are MIA. Will this still be a viable build?

Can you post a higher resolution picture so the experts (that's not me) can give a good opinion about the degree of damage.

Easiest way to fix this is to order a set of the SMPS boards (Switching-Mode Power Supply).? Hans offers them here:


People have had some problems with these boards (physical damage like yours, fried parts, etc.), and Hans kindly made replacements available at a low price.

Don't fret over shipping time.? You have some pleasant building-time ahead of you before you need the SMPS boards.

When you get to the initial power-up stage in your build, follow the instructions carefully.? Never (never never) exceed the input voltage on a QMX radio.? If you built if for 9 volts, never exceed 9 volts.? If you built it for 12 volts, never exceed 12 volts.? Over-volting a QMX radio can cause more damage, very quickly, than can be fixed.? Just skip all that disappointment and be careful.

And when you initially power the radio up, follow the instructions for reduced input voltage.? In the version of the assembly instructions I have, that's in section 2.31 Final Checks Before Applying Power the First Time.? Hans suggests 7 volts, current-limited to 250 milliamps, maximum.

Regards,
Rich

I did send Hans an email with pictures of the box before I opened it. Once he is back from his travels and can respond we will figure out best path forward.?

The 330uF inductor on one of my SMPS boards arrived in a similar condition on Thursday. The coil is intact, so I assume that it will function as intended...

From your picture, it appears that only a chip is off from those two 331 inductors. If that is all, I can't imagine that it would have any impact on functionality.?

Hi,

My parcel also come with damaged inductors. But my understanding of how it works convinced me to build kit. And no issue with power supply in my QMX HB.

One of my inductors was damaged during assembly. It works perfectly.

Thanks for the responses all. I did continue with the build so we shall see how it turns out.
