I-fc seems -to me, some-bimes, -tha-t ama-teur radio is 'becoming a li-t-ble like modern
ever/day living— with. no "time to stop and tender the li-fctle courtesierii that can
mean so much to "fche o'bher fellow on the band. Take a listen fo r a few-minutes and
see wha* I mean..... The unmodula-fced carrier tha-fc sits on -bop of a QSO and -tunes up^
-the dog-pile of "Neddies" tha-t call and call and call as soon as you start a-SX con-
-bac-fc^ 'th.e refusal to acknowl&dge a breaki-in sta-bi.on or al-fcerna-ttively -bhe s-fcation who
persists in -trying -to break in when yop: are o'bviously passing information along', and
so on. Mos-fc of which ase purely the resul-b of thoughtless ness<
It's never too late for new year resolutions. Remember the Amateur Code and.
abide by i-t, -thus bringing more pleasure and relaxation -bo your fellow amateur and

GENERA NEWS
QUite a few amateurs from the "Korth Island" have been on -bour in VK7 during
the past few weeks. These include 2AYR, 3APO, 3ZNG, 3ZER and:3ZNS. The dubious
ances-tory of the Hon. Ed. ^irrevocably proved in a visit -bo Port Arthur with Phil,
3APO, may explain some of -bhe daring and criminal editorials which appear from time
to time in this screed.
SL7AY/MIJ, -the Swedish -training ship, visi-ted Ho'bar-t recently and quite a few
contacts were made on both 3. 5mcs and 144 mcs. Some were lucky enough -bo visi-b the
ship and meet the two hams on board as well as inspecting the radio gear. I will
not a-b-tempt -bo spell the name of the ship, I-t would be a bo nut for a green CW op. Hi.
