    PRACTICAL WORK

    The generally expressed opinion that the Club .Movement is on the. \\'Rne hns been given n 1::1et- hack, and by no lesa an organisation than the South Randwick nnd Dist.dot Radio Club, which, a •hort ·hvelvo months a~o, wa.s not even formed.

    Following t.bat, by special permission of the PostmMter General's Department, Morse leso011S were trnnsmitted regularly from 2WW, Wireless Wcckly's experimental station, and hundreds gained t11eir knowledge of the Morse code from those trsnsmission.s which were followed regularly evn a• far away as Wes tern Victoria.

Proficiency. 1'he Cee a.sked is ~imply tho ordinary membership fee of tho Club.
