Preamp HF 160 meter DX receiving summary

Preamp Summary

Home ]Up ]


When comparing low-band preamplifiers the important
parameter is almost always output TOI. 

Output third order intercept is a measurement standard of how well the
amplifier stands up to strong signals with creating new “phantom”
signals through unwanted mixing.
