That sounds like the RF gain was just set too high in the Omni VII. I
have both radios here and I like the Omni VII much better. The Omni VII
is more convenient to use the controls. It's also more sensitive for
hearing weak signals on 6 meters.

Atmospheric noise (including lightning pulses) are stronger in my OM7 verses the Eagle. It maybe because the Eagle is a down converted receiver with a less broad front end whereas the OM7 has a broader front end (20 Khz I believe) and is up converted, plus the DSP isn't of the same vintage of the Eagle (just guessing).
