Using "Z" Mod on a scope.

[Murphyv310]

Original Aurora manual. The one sans modulator. Don't think it's on Darryl's website.

It is Jeffrey in the "legacy" section.
Mine is quite early but I borrowed your lead a few years ago and re-flashed the firmware. It is a brilliant converter and well used here, the lack of an internal modulator is of no great consequence as it is used for different standards that would need a differing modulator anyway.
