Totally wrong:

Here in Norway (60N), I usually have 10+ regular sats visible at all 
times, with 12 quite often.

In addition there are two or three possible transmitters of EGNOS (i.e 
Euro WAAS) corrections, so having more than 12 channels would have been 

In fact, my 76 CSx often have problems with EGNOS because it doesn't 
have any free channels which can be dedicated to this.
