All of them I flew had a continuous beam when on course.

The dashes you might be thinking of would have occurred with the marker
beacon light and audio when overheading a "Z" or airway marker along the
range leg (white light with three light system).

Hello All,

Hoping some experts/old timers might help me on a basic Radio Range
question.

I understand the principle of merging the A's and the N's to get the
on-beam signal.

I have been told that, while originally this merge created a
continuous, uninterrupted tone except for the station identification
every 30 seconds, that it later evolved to a "Pulsed on-beam tone"
i.e., a series of dashes when flying "on the beam."

Is that information correct? I'm looking for personal flight
experience here, if possible.

Thanks for any help.
