  Storno CQL 633FE

is a compact radio of the Stornophone 600L- series.
It is a solid state mobile radio in either the 2-m or 4-m-band; it uses crystals on up to 6 channels. The voltage used can be switched between 6, 12 or 24 V.

The front: Bedienteil CB 603 can be used as a remote control unit. It is installed in an extra housing, and thus can be operated from a distance of up to 100 m.

It has a built in loudspeaker; an additional loudspeaker can be connected.

I could not find out, if a BOS license existed, nor who used these radios or where they were used.

A channel spacing of 50, 25 or 20 kHz could be ordered on 2m and 4m.
