Amateur Radio at the Singapore Maker Faire 2015

Hi there! This year, a group of members from SARTS, including myself, took part in the Singapore Maker Faire and set up a booth there. We set up 2 booths, one being an EchoLink booth, and the other, being an outdoor HF station.

What made this event special was that this year’s Singapore Maker Faire is now a full scale Maker Faire event, and also, some of my classmates and I did this as part of a school project. I certainly do hope that they learned something of value from this event. I would like to say, many, many, many thanks to them for helping out with manning the booth.

Here are some photos taken from the event:

Visitors participating:

I met this visitor in the picture above 2 years ago, when we were participating in a 24 hour programming competition. It was nice to see him again, and it certainly was nice that he could still recognize me after 2 years.







This visitor, Mr Lim Khuan is a licensed operator, who came to visit our booth. Thanks for coming! Oh and don’t worry! I am still trying to fix your radio! =P

Well, it has been fun, and we’ll certainly do it again next year, if we can.

VHF repeater moved!

Hi everyone! Our VHF repeater has now been moved to its permanent location at Dover. It’s a better location as there are almost no obstructions in the areas surrounding the repeater.

The repeater was placed at Mr Jeff’s office, in the Bukit Batok Industrial area.

The repeater was not sensitive to weak signals, and it was hard to make contacts on the repeater, so Mr Jeff went back to the office on Christmas 2014 to tune the duplexer, and try to solve the issue.

The issue was due to site noise around the location, and the antenna was blocked by the building. There was a measured 14dB of antenna noise in the area. As a result, not much could have been done.







One day, Mr Jaya, 9V1AI decided that he would want to take the repeater back and install it at his place in Dover (We intended to install it there anyway).

Since the repeater was now in a new location, Mr Jeff sent out emails to the members of the SARTS, asking them to test the repeater from different locations. Quite a number of members, including myself, helped out with the testing of the repeater from different locations, and I have done a presentation of the VHF repeater testing in May this year.

Here are the slides that was used in the presentation: Here!

In any case, if you want to help test or use the repeater, here are the details:
You transmit on: 145.025 MHz
Repeater re-transmits on 145.625 MHz
CTCSS tone: 156.7 Hz

Please do leave comments about your testing experience, and help us test the repeater out!

Thanks for reading!
