Yaesu FTX-1 optima vs Yaesu FT-991A
Home / Comparison / Yaesu FTX-1 optima vs Yaesu FT-991A
Yaesu FTX-1 optima or Yaesu FT-991A? I put both radios side by side: data from the manufacturers’ datasheets and photos at the same scale. The Yaesu FTX-1 optima comes out better: a second receiver, an SD card slot, current draw on transmit and weight.
