Not a good test as his receiver will be grossly overloaded. Could be the
result frequency drift resulting in the IF of the receiver moving off
the linear part of the discriminator. Although I still favour the idea
that the listener fell asleep. I myself have reached a semi comatose
state reading your posts, many times..

How unkind! I laughed, naturally.
