WA Radio Scanner Users' Group

I think you'll find there are a few Home built Sims in Australia including a Full 747 Motion sim

There is a A320 in Melbourne, im good friends with the owner who is currently in Perth, and think of moving here (fingers crossed he brings the sim)

Have a look at this site http://www.worldflight.com.au/
7 Sims around the world spend 24 hours a day 7 days a week for one week in November?? non stop around the world on a online network called VATSIM, raising money for local charity's, including the RFDS in Aus

And there is a few 737 NG's about the country

I worked ATC online for the last leg MEL to SYD of the flight as Delivery, at Melbourne, and it was busy 90+ support flights.

If you have a intrest for ATC and want to do some controlling of the Virtual Skies, then head over to http://www.VATSIM.net

Then to the Aussie Division http://www.vatpac.org

Training starts as
Tower
Approach
Center

Ypu need to pass assessments to move up

I have a online rating that allows me to work Melbourne and Brisbane Center's

Wow. That was my first scanner back in the late '80s. Didn't have much spectrum.. just VHF and UHF two-way I seem to remember. Just enough memories to cover the analogue WAPOL metro. I also had the 144XLT which was the desktop version of the 60XLT but with a whole 16 channels.

This is my Shack

Diamond SX600 SWR Meter
Yeasu FT7800 2M/70CM
Computer Power Supply

Soon to get a Yeasu FT857

Hi Slipnot
Have you done any work on that PC power supply to smooth out the ripples on the DC output?
Also work needs to be done if you want to use it on a HF rig as they produce noise that will wreak havoc with your reception.
Cheers

Gday ZMS.
No I havnt,
Ive been told its ok becuase if they are to be used with senitive computer chps on a computer then they should be ok on a radio.

Is that what you mean or is it something else?

Well Gee every other PC power supply I've chosen has always had a draw line in the main supply bundle.
Did you have to make a connection through to one of the lines in the "main power" certainly most of the power supplies I've used wouldn't let you just run off the smaller cables you needed to have a motherboard or something plugged into the motherboard connector for it to work.

Have a listen to your transmissions on a scanner, if you have a hum its no good for radio without mods.

As I said previously don't bother using it with a HF radio.
Cheers

It might be an AT PSU which doesn't need any mod (except maybe a load to stabilise the DC). However you have mains on the power switch.
Using an ATX PSU can be done.. you just need to wire a switch between the PSU_ON line and GROUND (which is what the motherboard does to power it up). Google 'ATX bench power supply' or similar for more info. The good thing is you don't need to fool with mains at all. But read what VK6ZMS said as well I've used switchmode power on audio circuits... OK for testing, but they can cause a whine.

The noise is because SM PSU are generally high speed square waves.

hmm, well all ive done is connected the green wire to the black wire to turn it on.

Yep. With some PC PSUs the output voltage can wander high with no load on the 5V line (yes.. the 5 volt!) If the 12V is unusually high you need to put a resistor across the 5V line and everything will settle down. The recommendation I saw was two 47 ohm 1 watt resistors in parallel (From black to red) I'm using one on my dual bander and I've had no reports of hum. The receive side is sweet. Your mileage may vary with PSU brand and quality.
