The TV transmitter utilized the high-frequency output of a video recorder and was equipped with a self-developed high-frequency linear amplifier to amplify the output signal to 5 watts. The sound transmitter was self-developed with a 3-watt modulation transmitter and a four-pole Yagi–Uda directional antenna, made by Hu, Jialun (胡家倫). At that time, our university did not have a mechanical laboratory and had to rely on an outsourcing studio for production. However, due to limited ironwork skills, multiple modifications and reproductions were required to meet the specification. At the beginning, the transmitter was set up in front of the Chu-Ming Building (竹銘館), and the first trial in Hsinchu was successful. Then, the transmitter was move to the 7th floor of the National Education Data Center in Taipei and a three-day public trial was sponsored by the Chinese Institute of Engineers. During their trial, 5 televisions, borrowed from Yong-Kang Company (永康公司), were placed at the Music Station of New Park for public viewing.

From 1961 to 1973, Lan Jen Chu (MIT) taught electromagnetic wave antenna design and assisted in the establishment of departments in 1964. In 1962, McNally (Bell Lab), an expert in vacuum tubes, came to the university to give lectures and set up laboratories; In 1963, G. C. Dalman and I, serving as a lecturer, established a vacuum system (including ion, diffusion, mechanical pumps and vacuum chambers). Later, in 1964, I used these "scrap" old pumps to successfully build an Al-Evaporator system which can achieve 10-6 Torr! In 1964, Prof. Ding-Xun Wen, Prof. Chao-Chen Wang, Shing-Chung Wang, and Ding-Hua Hu (Prof. Wang’s master student) established the first laser (Ruby Laser and He-Ne Laser) and the Microwave Laboratory in Taiwan.

Core Ideas：
Claiming humanity as the basis of academic development, promoting the respect for teachers, and regarding success of education and recruiting of scholars as the conditions for the university to be at the top rank.

Telecommunications in Taiwan
After the passage of the Telecommunications Three Acts in 1996, the regulatory oversight and operation of the telecommunications industry, handled by the Directorate General of Telecommunications, were separated. True telecommunication liberalization had finally come after this separation, with the Directorate General of Telecommunications taking the initial step in 1997 by opening up four mobile communication services, including mobile phones, radio paging, mobile data, and trunked radio. The opening up continued with the introduction of satellite communication services in 1988 and the 1900MHz mobile phone service in 1989.
These services primarily involved the opening up of wireless spectrum resources and had relatively lower difficulty in infrastructure construction. Consequently, the mobile phone business indeed flourished, and by 2002, the mobile phone penetration rate reached 108%, making it the highest in the world at that time. However, the greatest challenge to telecommunication liberalization came later in 2000 with the opening up of fixed communication services and the establishment of related fair competition.
