It's no different than the original switching scheme, Hue, which is
step tuned. The intent of the C-37/ARR-2A "electric tuning control
adapter", which is synchronized with the compatible C-35/ARR-2A
channel selection switch, was to eliminate the problems of long runs
of flex tuning cable between the receiver and the control box. That
allowed more flexibility for where they could install the receiver.
The motor drive adapter was cleverly made to be capable of
installation on the original R-4A/ARR-2 receiver. Attached is the
installation diagram for the whole shebang.

this controlled; is it continuous
