Pride and joy working over ISS

Too many things to consider,and many more to overcome...that's why my blog is not updated! Too many projects and plans in the minds,but most of it..only half way through...I've try to build a simple and inexpensive APRS 1200baud decoder,but until today..no luck yet.
Luckily I got a call from Dex 9W2DTR, and he is very kind to sell me one of his collections of MX614P..he..he.. so the project will be restart once the MX614P in my hand.

So,that's one of the causes..well now I'm quite free during night,and I check the ISS schedule and come out with very nice pass during the night.So once again, I hook the interface to radio..and wait for ISS. It's been a long time...
Here's the result on ARISS website..

Day 1



Day 2

you can sent short EMAIL from RF to ISS to any recipients..well in this case...few unlucky guys..

my position... note the path


and once it digipeated by ISS...received by Thailand ham and feed to APRS server...

What else hobby give you opportunity to do thing like this?

And another pass is coming in 9 minutes..see you all..good luck .73

Packet Mode on ISS is back

Greeting fellow friends..

It been a while the packet mode on ISS is switch off.Maybe they are busy with their task..
A couple week ago, it been switch on, that is great news for many of us (ISS hunter).I've been trying to work several times since it back over the air during night time,due to better equipment and antenna. I'm also try to work from my portable (my work place), but no luck yet!

Ahh..a message from Indonesian station pop up just now...
One of the stations that I copy over the ISS


thank you sir, all the best!

this also one of the stations that I could gate in

my own station, digipeated by ISS

My current setup Icom 706 MK2Gburst 50W, running on 12V 7Ah x 2 battery,Cushcraft ARX2B.Interface, homebrew (named it RutBlaster..he.he)

Also will try the IC-910H soon..not mine!!

where are the Malaysian stations?

Power Supply Project by 9W2TTC

coffee by 9W2WF..thanks it keep our eyes open

Last Sunday 27 June 2010, few of us gathered at Mares Club House to join this activity.To build a linear power supply.Class was conducted by Mr.Mansor @ 9W2TTC.In this class we will learn exactly from the 3 pin plug 240AC to the final output of 13.8V that will be feed to our equipment.

Mr.Mansor on action...

this is the best circuit..

the "ingredients" for our soup...fresh and selected items only

heat sink banks from junkyard..

Even though the class only going on for few hours, but it good for me, I can sharpen my skill again. Well it been almost 11 years since I left my technical school (Sekolah Menengah Teknik Kulim).Mr Mansor elaborate us very detail of each and usage of every component. Why it should be this value and rating. (opsss...now I know why it burnt!)


DAIWA power supply

DAIWA factory claim 30A..after calculations....auchhh..< 20A

rectifier diode....Motorola tu!

Mallory...RM180...woooowww bigger than cup

The block diagram of the power supply now is in our head. For upcoming classes, there should be more fun...seeing from all the belongings of Mr.Mansor I could not imagine the condition of his base. I only could imagine my base...(messy..very messy)

from previous project belong to 9W2UIA

need a modification...add transistors, capacitors..etc..
Well folk, if you are interested in electronics..make a pit stop at Mares Club House every forth week of Sunday monthly.


Compaq? with terminal?

what..with ampere gauge and voltmeter?


ohh...finally the content..Mr.Masor still maintain the floppy drive..wonder why?
for logging?

So. see you guys on next class...
