MYCallsign – the Malaysian Amateur Radio Callsign Query Mobile Application has been updated, now it comes with a new spiffy logo. The mobile application can be installed on most Nokia, Sony-Ericsson, Motorola and Samsung phones. The application can be used to display information regarding an amateur radio callsign, such as handle (fullname), apparatus assignment (AA) and AA expiry date, and it is handy for recording QSO information in the logbook.
The application is licensed under the GNU General Public License 2.0 and is available for download at MYCallsign GoogleCode website
The new MYCallsign logo was created by Piju (9W2PJU – http://9w2pju.hamradio.my)
Take a look at this video shot on 3rd September 2010, where we can see that 9W2DI has managed to get contact from Macau, China on (28.495 MHz) 10 meter band! Apparently the 10 meter band is not dead like most people used to say. 9W2DI (Pak Din) is QRP hamradio enthusiast, you can see all his QRP video from his YouTube channel
Visit his blog for more information about his activities : http://9w2di.blogspot.com
My friend, 9W2AZV gave me the drawing for this 2 meter antenna, I haven’t tried building it yet. The antenna seems to share common design with a collinear antenna. I ran this schematic in MMANA-GAL and found out the antenna has a very nice flat radiation pattern which maximize the transmission reach.
Here’s the the antenna design:
One brave soul (9W2PJU)has made Garmin POI of ASTRA and MARTS repeater location available via Garmin by publishing the Garmin POI file on his website. Although from what I read, some people has complaint that the location information stored in the POI is inaccurate, IMHO the exact Amateur Radio Repeater location itself isn’t that important as the information that contains its frequency, tone and shift which can be use to access the repeater.
From my observation, the POI of the Garmin does not store the exact location of the repeater (probably for security reason) but the general location of the repeater is good enough for travelers to discover new repeaters and use them while traveling to unfamiliar places, keeping in touch with fellow ham operators.
Please refer to 9W2PJU website for the latest POI files.
Tak-Tenna is a type of compact antenna which is suitable for those who has space constraints on erecting their HF antenna. It is small enough that a 40 meter Tak-Tenna is just about the size of a 4-element Yagi 2 meter antenna. Here’s photographs of 40-meter Tak-Tenna in action. Compare that to the typical 40-meter dipole or Inverted-V configuration ! Thus it has the advantage of space-saving and unobtrusive setup when compared to other design of HF-antenna.
Tak-Tenna is available in 3 models – 40, 20, and 10 meters, with the 40 meter model can be use on 40, 30, 20, 15, and 10 meters with a tuner.
Refer to this article: “The TAK-Tenna™ Review – A Limited Space HF Antenna Review” for further review on Tak-Tenna performance and advantages.
Tak-Tenna can be ordered from the official Tak-Tenna website

MCMC (Malaysian Communication and Multimedia Comittee) has updated Malaysian Amateur Radio Apparatus Assignment and Callsign database, which can be viewed here – http://www.skmm.gov.my. The updated database include details of newly registered hams who’ve recently passed RAE 2008-1 examination in April.
Woops, seems like the SSN (smoothed sunspot number) count for this month is equals to 0.
I only manage to make 6 contacts with DX station on 10 meter during September. Partly due to bad propagation, partly due to my busy schedule, which kinda limit my ham activities to Sundays and Saturdays.
I’ve been getting all sorts of questions about working 10 meter from fellow hams in my place. I advises them against it as the propagation right now isnt as great as couple months before
Plus, I’ve known quite few local hams that regret that they venture into 10 meter unprepared, as it requires a lot of patience and different skills to work with.
In another note, I would like to extend my warmest congratulations to those who has passed the 2008 Morse Code test, more details in 9M2MGL website
