Hi Pedro,

You better check your equipment. I noticed one time a very bad wideband
transmission with a very bad tone sending LT7H. It was very hard to zero
beat. No wonder that your call got busted. I guess that not so many
people were answering you with such a bad signal. Can you see any gap in
the log appearing at the time when you had a big number of busted spots?

I worked you later and your transmission was then ok so it might be
related with an arcing bad connector.
