The fourth series of transatlantic

amateurs are concerned. They Will

During the first three transatlantic
tests North American amateurs were
determined to get their signals across
the water. Transmission was the pig
thing and meant everything to them.
| Even last year when signals from
United States transmitters were
hurled across the ocean by the nun

in the receiving end This was a
great disappointment to the french
and British hams.
| With the conditions for the present

tically rversed everything depends on
the receiving. and the time previously
used by each operator In getting his
entire apparatus into trim, VIII now

This opens the way for the free-for-

Another feature of the tests is the

thousands of dollars worth OF radio
