[CQ-Contest] IC-7300 VS IC-7410

Thu Apr 1 08:36:33 EDT 2021

Hi Frank,

The three different units I saw tested during contests from 2016 to 2019
here exhibited severe ADC overflow.

Sort of what is seen here: https://youtu.be/uVslSyqNbYk

But also with Preamps OFF and IP+ ON and reduced RF gain.

73,

Martín, LU5DX
