Trip to National University of Singapore’s Lab and SARTS meeting

Hi, Joyce here. This blog would be for me to share my experiences in the hobby of amateur radio. For those of you wondering what it is about, it is a hobby involving communication over the radio. Or in simpler terms, your own radio station that can be used to talk to someone else.

My blog will talk about my experiences that I have encountered, from the general stuff to the weird quirks that happen.

Now, last week and today, I managed to go to the National University of Singapore’s laboratory. More specifically, the electronics laboratory.

I met Dr Yong Fu, who does research there (I think? :P), and also operates an amateur radio station there. His set-up is a Yaesu FT-897, connected to an end-fed wire as an antenna, tuned using a manual tuner. Here is his radio station connected to the computer.








I also met a person named Mr Frankie, who was operating on the radio station to make a QSO (contact) with someone in the Philippines. This is Mr Frankie ‘on air’.








And yes, this is the antennatuner that Dr Yongfu uses. It must be manually tuned. And we were outside, at the roof, tuning the antenna (Yikes! I am afraid of heights! =( ) .  There is a term called SWR, or Standing Wave Ratio. Basically, it’s the ratio of the power being transmitted to the power being
reflected back to you. We always aim to get a SWR reading as close to 1:1 as possible so that all the power used to transmit the signal gets transmitted. However, that is not always possible. Anyway, here is the antenna tuner.








Hope to be there again soon. Dr Yong Fu also told us about Micro-controllers and FPGA’s. He has quite
a a lot of stuff in the lab. More to come soon.

Anyway, last month, and the month before, I went to the Singapore Amateur Radio Transmitting Society’s (SARTS) meeting. The previous meeting I went to about 2 – 3 weeks ago, was about the 2 meter repeater in Singapore, which was down for about 2 years. They had plans to revive it. Also,
there were more serious issues such as IDA of Singapore planning to take some of
the frequencies for other commercial telecommunications uses.

I met people over there, one being Mr Jeff, and the other being Mr Frank, an old-timer here.
Here is me speaking to Mr Frankie and Mr Frank.






If you are interested in Amateur Radio, why not go down to one of their meetings?

Anyway this is all I have for now. Thanks for taking the time to read my blog.
