Title: A.P.R.S (Automatic Position Report System)

Synopsis:
Explain what is all about APRS, how it works and what do with it.
Main reason about my second visit is to Malaysia is to help radio amateurs in this country, to understand a other side of hobby. So they start building digital electronics project for the radio amateur hobby. (APRS)

Date: 7 march 2009
Time: 10:30 am ~ 1:30 pm the length from the seminar is depends about visitors interest.

Vanue: Lecture Hall, UniMAP Kuala Perlis.

Info Direction QRV: 9M2RMK 147.9800Mhz Shift -0.600 Tone 203.5
Info Direction on :
a) Wikimapia
b) Google Maps

Those interested to learn more about APRS technology are invited to join in the seminar. It’s free of charge!

From what I can surmise, the slim jim has a slightly lower radiation angle than vertical dipole antenna and is easier to mount, thus it is suitable to use for point-to-point communication VHF-UHF operation. It has a gain of about 2.8dBi-3.2dBi in free space and 4.8-5.8dBi when mounted at about 30feet from the ground. Here’s the result of MMANA-GAL :

Step I

First get a ATX PC power supply from the nearest computer store. Price is around RM30-70.

Make sure it could supply sufficient current. Look at the label. We need at least 10-17amp at 12V for a sufficient operation of mobile rig. Lower Ampere rating means that your mobile rig cant transmit with a typical HiGH setting (50w).

Step 2

Look for ATX power connector. It should look like this.

Look for black and green wire at the ATX connector. The wire position is 4th from the top left side of the connector and 4th from the bottom right side from the connector as pictured above.

Cut the black and green wire. Trim all the other wires as we wont need them.

Tie both Black and Green wire together.

Connect both Green and Black wire to bypass the PC Power Supply unit. Insulate it with some tape. and switch on the power supply. If the fan is running, that means you’ve successfully completed this step!

Step 3.

Turn off the power supply. Look for HDD, CDROM power connector, as pictured above.

Cut all wire from the connector.

Separate 2 black wires and one yellow wire. Combine both black wires together.

Look for an extra mobile rig power connector, this can be obtained from electronic shops car accessories, or car battery shop.

Connect the yellow wire (+12 volt DC) to the positive terminal at the power connector as pictured above. Connect both black wires together and put it to the negative terminal as picture above too.

Step 4

Cut all unnecessary wires, connector, and leave the power supply with just the rig power connector like this. It will look much more presentable and neatly prepared.

You can test the output voltage of this power supply by testing it with Voltmeter/Multimeter. Here you can see that the power supply output voltage is about 12V, which is suffiecient to power a mobile rig (13.8V +/- 15%).

Step 5

Finally, connect the power supply to your mobile rig to power it up. Enjoy your QSO!

FAQ: Nice, but my mobile rig require 13.8VDC to operate, this PSU only supplies 12V, it won’t work
Actually it can work. Mobile rigs requires 13.8 +/- 15% VDC to work (check your rig manual). and that gives a range about 11.7V – 15.8V of stable voltage potential. So a 12V power supply with sufficient current (15A and above) is definitely sufficient to power the mobile rigs.

The most interesting part of the software is, it can help you to improve your design by projecting the antenna radiation pattern and estimating the radiation resistance (impudence) at any given frequency.

The application is created for the venerable DOS environment, thus some of the operating system might not be able to run it natively. However I found out that I can run the application successfully using DOSBox DOS emulator software under Ubuntu Linux. For your information, DOSBox is also available for Windows operating system too.

YagiMAX Screenshots

Here’s a couple of YagiMAX screenshot taken from my computer (running Linux, Ubuntu Gutsy). The antenna shown here is a 6 Element OWA Yagi for 2 Meter amateur radio band, scaled from its 6 meter counterpart, the design was taken from L.B Cebik website
