[RTTY] ZB2/SM4DH? 1993 CQWW RTTY Contest

[Don Hill AA5AU]

I'm having trouble reading this entry in the May/June 1994 issue of the RTTY Digital Journal (page 11) in the 1993 CQWW RTTY
Results.

The call appears to be ZB2/SM4DH with possibly one more letter at the end but it's too hard to tell.  Can anyone confirm the correct
callsign for this station?  I cannot find SM4DH in QRZ.COM and I'm thinking it should be a three letter suffix.  Any help
appreciated.

Thanks & 73, Don AA5AU
