My old 16-fret tenor has perfet intonation apart from fret 7 of the G string which is slightly flat!

Any ideas what could be causing this?

The first thing I would recommend is to scoot the bass foot of the bridge 1 mm. towards the fingerboard. Mark its current position with a pencil before you move it, so if that doesn't help or throws the rest of the banjo off, you can move it back to the same position. The second thing I would try is to change the string. Sometimes a weird intonation problem can be caused by
a "false" string.

How old is the string?

mikehalloran rcc56 String is a week old but has been loosened and retightened up many times. Is that likely to cause issues just in one spot? The intonation for the rest of the string is fine.

It could. Change it. Especially if the problem is new.

Finger pressure affects the note. Press too hard, it's sharp, and too soft, it's flat. I've got a banjo with uneven frets and have to make little adjustments my finger pressure across the fretboard, otherwise the notes will land sharp or flat depending on the fret.

Perhaps there's an issue with that individual fret.

Bad strings can happen, too thin or thick can throw intonation off. banjered

I agree with the finger pressure diagnosis. I have a Hopkins and I thought there were intonation issues and tried all the above suggestions. But a tiny modification of the finger pressure (on the 4th string) cured the 'sharp' intonation.

Different strings have different thicknesses and therefore have different distances to move before they touch the frets. Ideally the fret slots in the nut can be altered so that the distance from the UNDERSIDE of the strings to the TOP of the frets are the same as each other. Of course uneven fret heights can make this solution unworkable.

If the 7th fret intonation was fine before you changed the string, it would almost have to be the new string causing the problem. I'd change that string before doing anything else.
