Tragedi Tanah Runtuh Bukit Antarabangsa

Penulis telah menerima sms dan panggilan dari 9w2TLB dan 9W2CIA berkenaan tanah runtuh di Bukit Antarabangsa pada pagi sabtu @ 6/12/08. Kebetulan pula ramai antara ahli berdekatan telah sampai ke kampung halaman bagi persiapan Hari Raya AidilAdha. Disebabkan oleh kawasan komuniti wilayah V17 adalah yang paling dekat, kami diperlukan bagi menyediakan pusat komunikasi (Control) di HQ PBSM Jalan Ampang. Penulis sampai ke HQ PBSM jam 6.20pm dan seterusnya bersama beberapa rakan untuk menukar pusingan standby di pusat komunikasi sementara di Masjid Bkt Antarabangsa . Misi ini diketuai sepenuhnya oleh pihak Mares dan Presiden 9M2AU. Di dalam masa yang sama, pihak SCS telah mengosongkan penggunaan repeater dan memberi laluan kepada sukarelawan radio amatur menggunakannya sekiranya diperlukan. Terima kasih atas bantuan semua pihak.





Maaf kualiti gambar kurang memuaskan. Lokasi di Masjid berdekatan Bkt Antarabangsa.

ICOM 2200H MIC PROBLEMS

Hi,

Had a talked with 9W2WKR (Kareemi) few days ago, he claimed that he was really fed-up with his MIC problem. It was a common problem for ICOM 2200H and no one would ever deny it. Sometimes i'm also faced the same problem but due to time constraint, i'm not able to rectify further. Obviously, it was a challenge to me to discover and rectify the problem as this is a process of gaining a knowledge. Tried to surf and dig all informations from websites and forums but not really helpful.

I'm not able to rectify it on my own, then of course what's friends for? By gathered all informations from their own experience i believe we manage to get the root cause and avoid problem from recurring.

I'm using what ever resources i have and below are the findings.

Station : 9w2pro & 9w2wkr

Date tested: 14 November 2008

Transceiver set : ICOM 2200H (mobile rig)

Year of Manufactured : April 2008

Warranty : ??????

Comment:

Wonderful rig and performance plus the cheapest price in open market.

Most annoying problem:

  • No signs of Tx power appeared when triggering PTT. During QSO, when it happens, the other station will wait for a while waiting for your Tx but received no signal and audio at all.

Findings and observations based on setup station:

Mobile station

Perodua kancil

  • Battery NS40 Fluid Type ( 2 years old )
  • Fluid level - low
  • Power Supply direct tap from battery
  • First year - overall OK
  • Second year - Oftenly occured

Pajero

  • Battery NS70 Fluid Type ( 1-2 year old)
  • Fluid Level- low
  • Power supply direct tap from battery
  • More than 5 times occured.

Base station

  • Regulated switching power supply 12V
  • No problem encountered.

Suspected root cause:

  • PTT ( switch )
  • Cable from rig to Mic
  • Power output from rig
  • Battery defects

Action taken :

  • Change to another mic - problem persist
  • Smash down to floor - still persist
  • Re-fill battery water - no problem encountered until today

Theory but no facts:

  • Based on my personal experiences and secondary informations from friends & radio forums, it is not because of the PTT problems as what an ordinary people thought but technically because of power supplied to Microphone. For Yaesu FT8800, its only need 5vdc to operate compared with ICOM 2200H which need at least 8Vdc to operate. A supply voltage from battery is sometime fluctuated depending on battery performance. It is true that this type of transceiver has been tested but why the complaints keep increasing not declining.

  • It does happens when a supply current to rig insufficient and failed to distribute stable current flow to MIC (max 10mA).

  • By re-filling battery water and ensure battery is running well and supply enough current to rig, it will definitely may provide sufficient current supply to rig.

How to overcome this problems ?

  • voltage stabilizer - provide sufficient voltage and current supply
  • Buy new battery
  • Battery performance voltage checking e.g monthly or weekly
  • Last option - buy a new mobile rig except ICOM 2200H.

I'm not offering solution but only a recommendation. Try with your own risk. If this can make a change, it is my pleasure for you to share your testimonial or comments. At least, better from yesterday.

Menjelang RAE 2/2008

Cukup ke nota cari dalam internet tu??? Boleh ke lulus? Apa soalan yang akan keluar? Bagaimana keadaannya? Malu ke jika tidak lulus? ...macam2 persoalan bermain difikiran sebelum RAE.

Tips mudah dari saya.
  • Cari rakan radio yang boleh kongsi bersama ajar SOP dan Teknikal
  • Usaha
  • Komitmen
  • Masa
  • Sabar
  • Doa
  • Yakin pada diri sendiri

Tak cukup tambah sendiri la ye....lauk pauk dah disediakan...cuma kita sahaja yang pilih lauk mana nak masukkan dalam pinggan kita.

Musang Melaka di takluk V17 (ARDF)

Apa yang sempat saya coretkan disini adalah V17 sekali lagi berjaya di ARDF Melaka.

Agak QRL dengan tugasan maka saya hanya sempat pos beberapa gambar disini untuk tatapan semua.



Sistem pemberian hadiah hanyalah pada peserta pertama yang dapat mengesan musang tersebut. Kami 3 kumpulan dari V17 jika dikira ranking berjaya mendapat podium 1,2 dan 3(Jika dikira masa) . Alhamdulillah.

In memory of 9M2DS - Silent Key 28/8/08

Daripada ALLAH kita datang, kepada ALLAH jua kita akan kembali.
I wish to express my heartfelt condolences to friends and family of Allahyarham Pak Dollah (9M2DS) . Al Fatihah...
It is saddening because it was my first and last eyeball with Arwah Pak Dollah at Taman Tasik Titiwangsa for ARFD Central program organized by Marts Central on last July. It is such a great loss especially to all ham members.
Together i hope, we could unite and pray to ALLAH for him to rest in peace.
" Islam menganjurkan kita supaya selalu mengingati mati keranadengan tindakan itu, kita menjadi cerdas dan pintar serta lapang dada sebagai tanda hati sudah ditembusi cahaya keimanan.Manakala, orang yang enggan mengingati kematian adalah orang yang lalai kerana tidak membuat persediaan walaupun menyedari bahawa kematian adalah sesuatu yang pasti yang tidak dapat dihalang sebagai mana firmanAllah bermaksud: "Setiap yang bernyawa pasti merasai mati kemudian kepada kamilah kamu dikembalikan – (Surah al-Ankabut, ayat 57).

ARDF Malacca

Malacca....historical city...botanical garden....nice day....nice view.....arrghh....fox

Just my snapshot before we make a next move to Malacca end of this month in order to take part in ARDF Malacca organised by Malacca Amateur Radio Community.

Previously i was using this kind of antenna during ARDF Central just a few month ago.

I'll need to make a new kind of antena similar to Yagi but more sensitive. Still have to make it possible while still can. Okay....i need to arrange my time to do it.

Malacca...here we come!!!
