Regarding the de-Sachsen-Anhalt file, apart from 3 or 4 frequency 
entries the rest is useless being within the state, because regarding 
transmitters the areas are mostly not coordinated.

Brocken and Magdeburg are the only sites with Sachsen-Anhalt that are 

In fact, it is more common, that transmitters here are coordinated with 
sites from others states, e.g. "ARD-Das Erste" multiplex in Halle/Saale 
(Sachsen-Anhalt/Saxony-Anhalt) are coordinated with Leipzig 
(Sachsen/Saxony) and Gera (Thüringen/Thuringia), because this area is 
also topographically adjunct. "ZDF" multiplex is coordinated between 
Hale/Saale and Leipzig ...

This does not matter, as the transmitters in Brauschweig 
(Niedersachsen/Lower Saxony) and Halle/Saale (Sachsen-Anhalt) don't 
interfere with each other (the sites are more than 140 km apart) and 
there is a buffer zone of about 40 - 50 km between them, where you need 
a directed roof antenna to either receive one of them.

As I've experienced so far while travelling, that there are only very 
small parts in my federal state (Bundesland) of Sachsen-Anhalt where one 
can receive more than one transmitter site (and in most of this cases, a 
roof antenna is required, so you would normally have to direct this to a 
specific transmitter).

Well, I believe both scenarios(scan file for federal state versus scan 
file for a DVB-T region) have their pros and cons. :(

Fortunately programs like "Kaffeine" offer a full auto scan ...
