The handwriting on the diary matched that on the hate mail letters. When challenged, Mr Jefferson, 51, admitted sending the hate letters. He was given an £80 penalty notice for wasting police time.
The former motor engineer said his actions in sending the phony hate mail were "totally out of character".
He claimed the noise from the neighbours had stopped because they knew the council had installed the recording equipment.

"Sending the mail was out of character. We do not normally do things like that. We are not bad people. We have been dealt with by the police and received the penalty notice which we have paid," said Mr Jefferson.
Insp Simon Jessup, of the neighbourhood police, said: "We take reports of antisocial behaviour very seriously and work closely with our partners in the council and housing to get to try to get to the bottom of people's complaints.
"False reports waste a significant amount of time that could be better spent by police officers and council officials in meeting the needs of people with genuine complaints.
"We hope that highlighting this case will serve as a deterrent to others who think they can get away with wasting our time. Although a penalty notice has been the appropriate punishment on this occasion, people can be charged with wasting police time and can receive a criminal conviction at court."
When the YEP called at the neighbour's house there was no answer.
