I was listening on 20M a few nights ago and heard a station with the

The op said it was an expedition.

Are special calls assigned without numerals?

SY8GE?

I suppose it's possible the British authorities have issued a two-letter
callsign, though that would be contrary to the international Radio
Regulations and while some countries wouldn't care, the British do seem
to observe them. It's also possible it was a pirate but I'd think a
pirate would use a callsign that wouldn't stand out quite so much!
