I received a letter today that my signal "has severe splattering" as of 4/30/2019 15:30 UTC. I was not aware of this and would like any suggestions on how to check if my radio is "splattering" and if so how I would go about identifying the source of the problem so I may properly address it. My radio is a Flex 6500 and my antenna is a 29' vertical wire into a 9:1 balun.

Since the letter did not indicate who it was from I am unable to contact the sender for his input.

Any thoughts, comments or suggestions would be appreciate.
