Ml\u00e1de\u017e sledovala z\u00e1vodn\u00ed provoz, kluci si zkou\u0161eli zapisovat spojen\u00ed do pap\u00edrov\u00fdch blanket\u016f, jak se to d\u011bl\u00e1valo p\u0159ed deseti \u010di dvaceti lety, a \u0161lo jim to velmi dob\u0159e.

Jeliko\u017e se jednalo o prvn\u00ed akci podobn\u00e9ho druhu na KV jak pro OK1KEO tak pro radiokrou\u017eek NTM, \u0161lo hlavn\u011b o sb\u00edr\u00e1n\u00ed zku\u0161enost\u00ed.
