Description :

Mobile HF transceiver for outdoor or car operations. The X108G Xiegu, upgraded from X108, has 0.5~30 MHz general coverage receive capability. A Double balanced diode mixer is employed for the frequency conversion with 9 double tuned bandpass filters on the font-end covering all HF amateur frequencies including WARC bands. The transceiver is equipped with a minimum number of switches and controls on front panel for a easy use. Split frequency operations, the radio will receive on VFO-A and transmit on VFO-B. Standard 0.5 ppm TCXO as clock source. Narrowband 500Hz IF filter for CW. Noise blanker in 4 levels. Squelch. Build-in S-meter, power meter, SWR meter. The package includes hand speaker/mic with keypad. Front & rear handles.
