SWL之史海钩沉----美国之音泰国转播台之谜

美国之音冲绳转播台始建于1952年，自1953年中开始播音。
此台于1977年三月14日国际标准时1500结束播音。发射台位于日
本冲绳北端一个名叫 Okuma(音)的小村庄。电台拥有六条MW发射
塔，发射方向315度和17度，总占地134英亩。电台最终建起了一
台15千瓦、3、2台35千瓦和一台100千瓦(用于广播)或 5千瓦(用
于RTTY)，而 Poro转播台最初的建设方案几乎同冲绳台的如出一
辙(建立一条1000千瓦的中波发射机和2台35千瓦的短波机)

Construction of the VOA Okinawa stn started in 1952 and operations started
in mid 1953 [like at Munich Erching 173 kHz longwave beast, /wb]. The
final sign off was on March 14, 1977 at 1500. The location was Okuma, a
small village located near the northern tip of Okinawa. The stn had six MW
towers producing beams at 315 and 17 degrees. The area occupied at the end
of operations was 134 acres. The final SW setup was 1x15 kW, 2x35 kW,
1x100 kW for bcing and 5 kW for RTTY. The original Poro stn was
constructed with almost identical plans as the Okinawa site (should be
1x1000 kW on MW and 2x35 kW on SW /oa).

美国之音泰国转播台位于曼谷北部 107公里的 Ban Ra Som
(音)。那一千千瓦的发射机由两台五百千瓦的科林斯发射机组成，
这样的组合已使用了25年(始于1978年)。发射台北部建有三条天
线塔，每条均不超一百米高。泰国转播台的正常播音始于1968年，
在冲绳台关闭后部分设备也运到了泰国。


VOA Thailand (Bangkok), located at Ban Ra Som, 107 km north of Bangkok.
The 1000 kW tx consisted of 2x500 kW Collins transmitters, and the age of
the txs was given as 25 years (in 1978). There were three towers, each
just under 100 m height, in the northern section of the site. Regular
txions started on 22 February 1968. The article also says that parts from
the closed Okinawa tx were on their way to Thailand.

显然泰国台的科林斯发射机也是于1953年设立的。问题是这
些发射机在1953年和1968年之间用来干什么的？是执行秘密任务
还是封于尘埃？

OA comments: Apparently the Collins tx used in Thailand was also built in
1953 at the same time as the other big ones. The question then is what
this tx was used for between 1953 and 1968. Was it used for secret
operations or was it just kept under dust covers?
