The setup I used is in the image below:
?
Power supply is from 3, 3400mAh 18650 Rechargeable Batteries in the
?
Microphone was made from a old earphone/mic PTT - seen in the front with silver button and hot glued foam windshield.? This tiny mic. works very well for what it is.
?
Also shown (on the right) is my Iambic key that I made and encased in figured wood :)? I prefer this to a duel paddle key, though it takes two hands to use.? I have a bulk supply of the components, including PCB, for the small VK3IL Pressure Paddle key if anyone is interested in it as a kit or complete.
?
This was connected up to my 160m EFHW!

Huge thank you to Hans for making the QMX even better!!!? As an old programmer I am in awe how Hans can make such a simple LCD interface and a few buttons work so well together.

Such great performance from such a small 'package'.
