It is a 50W intelligent portable shortwave power amplifier. With high-speed automatic transmission and reception switching, it can automatically switch between receiving and transmitting without using an external PTT control line. Similarly, Hamgeek Micro PA50+ also enables high-speed automatic switching of LPF filters, and there is no need to connect the band control line, any QRP shortwave radio station can be used perfectly. And it has perfect power and standing wave display and protection functions; voltage display and protection functions; temperature display and intelligent heat dissipation and temperature protection; and the CW semi-plug-in mode function has also been added; of course, it also supports the use of external PTT to control receiving and transmitting switch and band control line switch LPF filter, and support for band switching protocol andXIEGU brand band switching protocol at the same tim\u003c\/span\u003e\u003cspan style=\"background-color: rgb(255, 255, 255);
