Home / Comparison tool / DL2MAN (tr)uSDX vs Yaesu FT-818ND
DL2MAN (tr)uSDX or Yaesu FT-818ND? I put both radios side by side: figures from the manufacturers’ datasheets and photos at the same scale. DL2MAN (tr)uSDX comes out better for transmit current draw and weight; Yaesu FT-818ND for output power on HF, 6 m, 2 m, 70 cm and AM.
