Around the time of Coventry British Jamming of the German blind
bombing system was mostly ineffecvive despite claims to the contrary.

Source, please?

Mike, Knickebein (SP) most certainly was jammed - I've interviewed KG airmen
that rode 111s, 88s, and 217s during this period and the jamming was hit or
miss, but definitely it worked on occasion.

Yes, I know it was jammed. What I wanted to know was the source of the
claim that it was 'mostly ineffective'.

The 'Wizard War' was active almost
from the first siren of the conflict.

Long before that.
