[ARC5] [Boatanchors] Taylor Super Modulation and Rothman Modulation

[Dennis Monticelli]

I have a Marmax MT-52 Mobile Transmitter with the MO-52 Mobile (Rothman)
Modulator.  It is in good overall condition, but unrestored, so I cannot
comment on the effectiveness of the modulation scheme.

I have never seen or heard of another Marmax product until I read your post.
