REA Modulation monitor in operation

This is a short video of my modulation monitor in operation. It is monitoring my Johnson Viking Valiant in a conversation with my Brother on 160 meters.
Finally a piece of equipment that allows me to see what's really going on.

Thanks for posting - I just ordered one for my homebrew AM rig running a James Millen amplifier with push pull 812A, modulating it with a pair of 4-125A and a BC-610 modulation transformer. It is on my YT channel and QRZ page. 73

Now that's a Transmitter.
