KP990 100W Short Wave Power Amplifier KN-850 KN-990 FT-817 FT-818 KX3 QRP

English Version KN-990 HF 0.1~30MHz SSB/CW/AM/FM/DIGITAL IF-DSP Amateur Ham Radio Transceiver Spectrum + English Manual

KN990 is a short wave full segment transceiver with medium frequency DSP technology.​The system language is English !

Note: After receiving the machine, use a USB flash drive to back up the machine’s configuration file. the configuration file may lost when upgrade firmware ! At that time, as long as you import this file, it can return to normal.

KP990 Added manual switching band and RF triggering transceiver circuit. In this way, not only perfectly cooperate with KN850 and KN990 to achieve fully automatic operation, but also can use manual mode with any QRP short-wave radio station below 20 watts. In manual mode, the transmission and reception conversion will use the RF trigger mode, thus achieving A universal power amplifier.
