Testing Chinese HF linear amplifier DIY kits 70W SSB linear HF Power Amplifier For YAESU FT-817 KX3
Linear que pode ser usado no ararinha, QRPs, FT817 e outros. Nos testes você pode ver a potência real de saída em CW key down. Fiz uns testes em FM também é mesma coisa. Muito bom amplificadorzinho, inclusive para testar toróides desconhecidos, mosfets, enfim, dá pra usar como pesquisa. https://www.aliexpress.com/item/DIY-k...
