I received a defect device that should have been discovered in quality control. Both ADF4350 PLL generator chips were defective; only noise above 140MHz. The unit also does not boot occasionally, especially on battery although there is enough charge. The power supply circuit does not include the latest changes. The seller requested return&refund but does not offer free return or local return. As returning the unit would have cost me about half the item´s price, Aliexpress settled the dispute and refunded. The store´s attitude during the complaint could have been better.
Device is great :)
