Original poster: dest <dest@xxxxxxxxxxx> Hallo. self-quenching of rsg is just another "coilers" myth, otherwise you wouldn`t see such things as "flaming rotary", "wheel of fire" and so on, poor dreamer`s disaster : D as regards the ssg - imo "coilers" just don`t "mastered" it enough, that`s all.
One might also bear in mind that many, many broadcast stations in the days of "King spark" used fixed gaps, both of the multidisk gap and the blown Marx gap varieties. The latest issue of IEEE Proceedings has pictures of the former type of a gap in the biographical article at the end.
Rotary gaps are nice when you need to force a particular break rate (as a form of modulation), or when you're doing something like running a radar modulator (again, requiring a reasonably controllable PRF).
