The Xiegu G7250 is a direct RF-sampling SDR transceiver designed for HF and 6-meter (50 MHz) amateur bands.
Key Highlights
Avant-Garde Split Design:
The detachable 7-inch control head can be separated from the main RF body deck. They can be deployed remotely (via Ethernet connection up to 100 meters away), making it ideal for tight shacks or flexible mobile/remote installations. 100W Output:
Delivers a full 100W output on HF (0.5–30 MHz) and 90W on 6 meters (50–54 MHz). True SDR Architecture:
Uses direct RF-sampling with a real-time spectrum scope and waterfall display on the main screen. 7-Inch Touch & Physical Controls:
Features a high-resolution capacitive touchscreen alongside 19 physical buttons and control knobs. Lightning-Fast Automatic Antenna Tuner (ATU):
Internal tuner handles impedances from 20 to 150 ohms with per-band memory tuning in under 0.1 seconds. Network Baseband Streaming:
Supports streaming baseband signals over a local network, allowing external PC software (like HDSDR) to handle remote receive and digital workflow processing.
