That sounds to me as though you have the input set for MIC rather than

First I would suggest using Line In and use DATA mode (AFSK A submode),

One safe way to clean any set of contacts is to use a strip of paper -

Slide the paper strip between the contacts, gently close the contacts
and pull the paper through.
