Well, your on the right track using an O-scope.

Maybe Mark can do some testing also. It is quite as easy thing to check.

First you need to use a AM broadcast type processor--similar to the Inovonics 235 that has adjustable negative and positive modulation controls. The negative is with a 1k tone ...

Hi Mark,

Glad to hear about the modification for positive modulation.

Did you measure on a scope how much positive ?

130% positive would be great.

Let us all know.

thanks
