NO EXCUSES! Bench test and on-air review of the new Xiegu G7250 HF/6M 100W transceiver. I test real RF power output, DSP filters, current consumption, compare receiver sensitivity against the Icom IC-705, and test on-air TX audio via a remote SDR receiver in England.
⚠️Please note that I was unable to perform the spurious emissions test due to not having the appropriate high-power RF attenuator on hand.
Is this two-piece SDR transceiver the honest 100-watt contender amateur radio operators have been waiting for, or does it come with hidden compromises? Here is everything you need to know.

📡 Key Highlights from this Review:
- Form Factor: Detachable front panel with heavy-duty metal desk stand, connected via 1.5m DE-15 cable.
- Filter Performance: Sharp DSP filtering on crowded bands with dedicated shape controls.
- Measured RF Output: True ~100W output from 160m through 6m, down to ~3W minimum power.
- Sensitivity & S-Meter: Deep dive into how the G7250 S-meter compares with Preamp 2 activated vs the IC-705.
- Efficiency: Standby current, full 100W TX current draw (~16A @ 13.8V), and cooling fan acoustics.
