Garden portable with the QMX+

Just a few days ago I had my first SSB QSO with the QMX+. It was from LA to PA - Norway to the Netherlands - on 20 m using a vertical quarter wave antenna.

 

The speaker/microphone is a "For Kenwood" Chinese speaker mic bought for a Baofeng some years ago. I replaced the microphone element with a more sensitive one that I had in my junk box. 

Surprisingly, the speaker gives adequate volume without an amplifier. The speaker is 8 ohms and connected via to 33 ohm resistors from the left and right audio outputs of the QMX+. The resistors are the only components in the little square box that the speaker-microphone connects to. I don't feel any need for any audio amplifier.

The battery is a 20 000 mAH Power Delivery power bank with a cable that gives 12 Volts to the QMX+.

The antenna can barely be seen here in the background. It is a Chinese whip antenna with the red base and 10 radials spread evenly.
