Imagine my surprise when my friend, Donald K. deNeuf, WA1SPM wrote
about ms PRINSENDAM/PJTA in the Summer 1988 Issue of Morsum Magnificat. I
used to QSO Don frequently on the SOWP net and the PREWI net - they
used to be held right above 14,100 kHz in what we called the "foreign
'phone band" - we'd be left alone no contest QRM ever bothered us -
except during a SSB contest!
