Product introduction: this section KN920 shortwave radio specifically for amateur radio development, because of advanced humanized design, cheap price, it's easy to learn to fit at the same time, so is well received by industry the lovers. This paragraph in shortwave radio multichannel transceiver, various work modes, internal circuit and high-speed microcontroller computing storage frequency, control tuning. LCD screen visual display parameters, users can very convenient manual input, storage, frequency, switch mode, etc. The fuselage panels with handles on both sides, is very appropriate also carry radio field to communicate. At the back of the fuselage with a cooling fan, cooling operation during launch.

на задней крыше - радует USB-разъем !

по внешнему виду напоминает кустарную поделку. Вариация на тему "широкополосная CB-шка" Думаю что как он стоит, так и работает.

Прикольненько! Продолжение KN-Q9, KN-Q10?

Была же тема.
Китайские КВ-трансиверы

может быть это degen в мире кв-трансиверов и через год здесь будет 300 страниц?

надо изучать схемотехнику, смотреть внутри что, фунционал и пр. т.к. описание куцее...

Третьесортный трансивер. "Сырые" и конструкция и прошивка. Правда широкое поле для доработок и модернизаций. "Дегеном" мира трансиверов я бы его не назвал. Дороговат.
