NanoSpeaker (KT-019 prototype) - Field operation with ultraportable active speaker (2 W)
The video shows tests of the new portable speaker KT-019 (in prototyping), which is essential during POTA/SOTA operation. This speaker is active, powered by any voltage of 7-18 VDC, has a built-in class D amplifier and a power of almost 2 W. The modern neodymium speaker provides high power with a miniature size and dimensions. The entire speaker weighs only 70 grams. This is probably a better solution than the popular JBL Go series speakers.
The production version will be black with white prints (as KT-005).

The video shows field operation of the QCX mini TRX with a KT-005 ATU and a 14 MHz longwire antenna. The antenna was about 16 meters long and was hanging loosely on a tree nearby. No dedicated grounding was added. As the tests showed, a range of about 1600 km was achieved. For more information (datasheet), please visit: www.krait-technologies.com

Example of using KT-005 ATU with QCX-mini transceiver. The video shows switching on the ATU with Pi power measurement, then tuning step. A moment later, after the characteristic sound of switching relays, you can see SWR ratio of 1:1.5 (or lower) and again Pi power measurement. The video was recorded using AMPRO-20 antenna. The QCX-mini and ATU were powered by 8 x 1.2 V AA batteries. For more i...
