While we are on the subject of ATC using multiple freqs by the same controller let me ask this.
In the US (or in the old country for that matter) is there an ATC rule/procedure that says you can't just move the users to one freq?
eg. On weekends when the tower presumably has less manning, they routinely have one controller working ground and tower (sometimes clearance as well) yet working 2/3 different freqs.
This leads to confusion and stepped on transmissions as the users are unaware (initially) that one ATC person is working multiple stations (and functions). Sometimes ATIS will state that "tower and ground are combined on xxx.xx" but often times there is no such warning.
Anyone have a clue why they don't just put everyone on the same freq so we don't step on each other or worse miss a critical clearance?
