More extracts from the Mercury re the Hobart Domain Wireless Station
	which opened in 1912.	Richard Rogers VK7RO 5/6/93

	The Mercury, Saturday, December 13, 1924.

	Radio Notes.
	An Antiquated Station.
	For successful broadcasting we must have a minimum of interference . .
	The Domain Radio Station, Hobart, will cause unlimited annoyance unless
	it is modernised several aeons. . . . VIH is a 5 k.w. spark station
	dating back a considerable time, and is of the most antiquated design.
	. . . VIH . . . has . . . a de Forrest ultra-audion set, which does its
	duty as well as can be wished.   However, the the grudge is not against
	the receiver, but the transmitter. . . . Any spark station is liable to
	interfere if close enough . . .

	[ The first broadcasting station in Tasmania, 7ZL, opened four days
	later, on December 17, 1924. ]

	COMMERCIAL INTERFERENCE
	. . . A large number of listeners near Hobart had hoped to hear the
	result of the [Melbourne] Cup as it was broadcasted from the racecourse
	by 3LO.	Just as the actual result of the race was being announced the
	commercial station commenced to transmit, and blotted out the names of
	the horses.

	HOBART RADIO STATION
	It will be good news . . . for broadcast listeners, to know that the
	wireless telegraph station on the Domain at Hobart has had the old
	spark wireless transmitter dismantled, and there is now installed in
	its stead a very fine transmitter of the thermionic valve type.
	The valve transmitter is of the 2 K.W. type, specially designed and
	manufactured . . . a note of any desired pitch may be transmitted.
	There is little apparatus compared with the old spark station. . . .
	The new apparatus . . . is also capable of transmitting on the
	continuous wave system, and when necessary can be adapted for wireless
	telephone transmission.
	In association with the special valve transmitter, the Hobart Radio
	Station is equipped with a 4-valve receiver. This receiver was made to
	meet all requirements of a modern coastal radio station. Although the
	receiver has provision made for four valves, it is so designed that any
	number from one up to four may be used, as circumstances may make
	necessary.
