”Recently while going through my collection of old
photographs that
began in 1958 during my career at Radio & Television Singapore (RTS)
on Caldecott Hill, I was suprised to find a set of photographs of
Jurong Transmitting Station (JTS) which was taken on 13 October 1962.
The subject was an Open House cum Swimming Competition Invitation by
(JTS) to staff of Caldecott for a friendly match.
JTS occupied an area of more than 5 acres. It
was situated at 14 M/s in Upper Jurong Road near where the Nanyang
University Arch once stood. JTS housed the aerial
field, the transmitting complex and quarters for the JTS and Telecoms
staff. Both shared a common entrance. Situated on one side was the
Telecom Station, and on the opposite side was JTS. The transmitters
were used during the Japanese Occupation in the 40s for the AM
transmission. Later it was used for AM/FM, Short/Medium waves
transmission until it was closed down in the 1990s. The whole
compound was shared among the staff of Singapore Broadcasting
Corporation (SBC) and the staff of Telecom. They joined the same
"Jurong Club" within the premises, patronised the same canteen and
shared certain living quarters. The total combined
population was about 200 over people. The premises of JTS and
Caldecott Hill were protected areas then.
On the afternoon where these photographs (No 3 to No 11) were taken,
Mr. John Duclos, then Director of Broadcasting, lead a team of 40
staff from Caldecott Hill. They left Broadcasting House by our own
departmental transport to meet our Jurong colleagues. Among them were
Mr. Lee Hoong Fong (Commerical Manager - Radio), Mr. George Ang (Chief
Engineer), Vernon Palmer, Steven Lee, Harry Crabbe (Eng. Progs.),
Andrew Dumon, Baseron Jummat (Engin. Section), R. Domingo (Orch.),
Paul Thomas, Lang Ree Chin (Library) and myself (Recorded Progs.)
together with their family members to give their support.
Upon arrival, we had a friendly introduction and we were briefed on
the complex, which consisted of the following:-
a) An Admin. Office - used by EIC, supervisor and typist clerks.
b) Main Storeroom.
c) Generator Room - standby generator for emergency.
d) Sender Hall - which housed the short wave transmitter.
e) Transmitting Hall - which housed the medium wave transmitter.
f) Cooling Pool (20' X 30') approx. - a water storage pool of cooling the
transmitting valves.
After the tour, staff from both stations were engaged in friendly
swimming competition which took place in the Cooling Pool. In between
the events, both staffs and competitors volunteered to put up some
hilarious items to entertain the audiences and their families. One of
the popular and memorial events was the participants facing each other
on top of the pole over the pool trying to knock his opponent into the
water.
The meeting ended with the presentation of prizes of appreciation by
Mrs. John Duclos to participants who took part in the various events,
which was followed by a tea reception.
The memories of AM transmission in Singapore took us through the first
transmission on JTS on 1 June 1936, it covered the whole of Malaya
Peninsular and the following wavelengths were allocated then:-
Singapore, short wave 60 KHZ & 308 KHZ, medium wave 380 KHZ & 225 KHZ.
Kuala Lumpur, short wave 49 KHZ and medium wave 432 KHZ.
Penang, short wave 455 KHZ & 366 KHZ.
Later, Kranji Transmitting Station (KTS) situated in Turut Track,
Kranji, started operation on 1 January 1994 with short wave services
transferred from JTS (Photo 1 & 2) after the closure of medium wave on
31 December 1993.”

I believe the frequencies are incorrect. Medium wave frequencies range from 530kHz to 1600kHz and short wave from 4.9MHz to 22MHz.
Based on the numbers, I believe you are actually refering to the wavelength in metres, which was the old way of denoting the frequency.
Medium wave range from 187 to 566 metres and shortwave frequencies for RTS are 60m, 49m, 41m, 31m and 26m band, which if memory serves me correctly are 5035kHz, 6130kHz, 7120kHz, 9145 or something like that and 11945kHz.
