I was interested in the hype of BEKO HLV1470, Spurious-70dBc, and ordered it, but it was -50dBc up to the surprising 4th harmonic. Is this the power of BEKO? Please let us know if you know the situation. Did those who have already purchased it actually measure it? Please let us know the result if you don't mind. stay safe and take care. de JA6AHB
