PENNANT HILLS STATION.
On Saturday Mr G. G. Balsillie, the Federal wireless expert, commenced a series of experiments with the new wireless telegraphy station at Pennant Hills, New South Wales, prior to taking it over on behalf of the Commonwealth from the contractors. The station is to have a guaranteed range under all conditions of 1250 miles and Mr Balsillie will make
tests under all possible circumstances in the next few days. For long-distance purposes he intends to try to open up communication with H.M.S. Pegasus, which is on her way to the China Station.
