Introduction

Thanks very much for your purchase of the kit. I expect you’re keen to get started so I’ll try and keep this brief!

All the components (including a blank SD Card) are stored within the six component packs. Each pack has a BOM attached to it. Feel free to empty all of the packets into a container for easy retrieval, checking the contents as you go.

Important note

These instructions have been lifted from the printables.com page which contains the STL files and BOM you’d need to print your own case.

Microphone element polarity

There are two elements available; the “Standard (CMA-6542TF-K)” (shown bottom) and “-24dB (AOM-5024L-HD-F-R)” (shown top).

Below is a picture which shows the polarity of the two microphones, as a guide.

QMX Microphone Calibration for SSB

Thu, 17 Jul 2025 12:36:43 +0000

This process works for any microphone and is not limited to the G7UFO (Assembled) Turret or the K6ARK Kit.

The -24dB (AOM-5024L-HD-F-R) element is recommended for the QMX as it was the element used during development at QRP Labs.

Hans has written an excellent guide (search for the Microphone test tool heading on that page) detailing how to setup the QMX with this microphone element. By default this is set to +50dB but its worth running through this to get the best setup.
