Tried it, no luck.

I did get lock on a single station on GRI 80000. However, it needed to 
use much of its amplifier.

I seems to see strong transients. Wonder if these really are switchers 
in the house or not, especially as I can see 1 ms distances.

Need a better time-recording setup to make sure I interpret the strong 
signals properly.

Cheers,
Magnus
