Wireless telegraphy is in process of rapid development at the present
time in Sweden. In 1910, was opened the first public coast station,
erected by the naval authorities at Karlskrona; in 1911, was opened the
station at Gothenburg, erected in common by the Naval and Telegraph
Service, which was afterwards taken over by the Telegraph Service; in
1912, was opened the wireless telegraph-station at Trälleborg for the
State Railways, which, however, is only used for the transmission and
reception of messages to and from Sassnitz and the steamtrain-ferries
on the route between Trälleborg and Sassnitz, and, finally, in 1914,
a station at Vaxholm was opened for public service. Thus, exclusive of
a number of stations operated by the Navy or erected for instructional
purposes, there were, at the close of 1914, a total of four coast stations
open for public service. The number of shipstations, which, at the close
of 1912, was 42 had, by the close of 1914, increased to 63, of which
number 26 were on mercantile vessels and 37 on warships. Of the
former, there are stations for the use of the public on the Thule S/S Co’s
steamers "Saga" and "Thule", running between Gothenburg and London,
and on the two steam-ferries running between Trälleborg and Sassnitz
— although the two last-mentioned stations exchange telegrams only with
each other, and with the coast-stations at the two towns in question.
The other stations on mercantile vessels are intended principally for the
convenience of the shipping oompanies and vessels alone; the Naval
ship-stations for naval correspondence alone.
The coast-stations are arranged on the Telefunken system, with musical spark
(tönende Funken), a system on the elaboration of which a Swedish engineer,
R. Rendahl, has expended much meritorious labour. The normal ranges by day
of each of these stations is 350 nautical miles, except that of Trälleborg, which
is about 250 nautical miles. The wireless system of the ship stations on trade
vessels is the Telefunken, except on 10 of them, where the Marconi system
is in use.
The fee for a radio-telegram is made up of the ordinary telegram charge
for despatch by wire, a coast charge, which falls to the share of the
coast station, and a ship charge, which belongs to the ship station. For
the Swedish coast stations, the coast charge is 10 ore per word, with
a minimum total charge of 1 kr. per telegram; the ship charge varies
on the different boats, and runs from 10 ore per word and a minimum total
charge of 1 kr., to 30 ore per word and a minimum charge of 3 kr. per
message.
The traffic- and income figures have, of course, not yet become of any great
importance. During 1913, the coast stations together received or despatched
3 193 paid messages, comprising 40 263 words, the coast charges for which
amounted to 4 381’6o kr. During the first seven months of 1914, this kind of
traffic largely increased, but, as, for well-known reasons, the number of sea-going
vessels within the range of the Swedish coast stations during the latter part of
the year was greatly diminished, the figures for 1914 are scarcely higher than
those for 1913. The ship stations on board Swedish vessels during 1913
dispatched altogether 2 872 paid messages, comprising 32 736 words, and received
4 791 messages comprising 8 651 words; the ship charges for these messages
amounted to 4 404’60 kr.
