It's wasn't me...!!!

Well..he did it again..

Last time i got a called from 9w2ZAE saying to me that i wasn't show up when an Astra net controller calling for me..

It's wasn't me...!!!

Just now again i got sms from 9W2TPT saying the same things but he recognised my audio quite well.

It's wasn't me...!!!

It is beyond my control and i plan to lodge a report to MCMC as they have the power and authorities to investigate further...just take 5 minutes from my office at Cyberjaya. Ok then..i was grateful to have friends who care for others..thank u guys

ARRD 08 - PORT DICKSON

Assalamualaikum dan Salam Bahagia,



Kita sedia maklum mengenai acara ini yang berlangsung di Port Dickson pada tarikh keramat 13 Dec 2008. Saya bersama dengan 9W2GSR dan SWL Mamak juga tidak ketinggalan hadir ke lokasi tersebut. Agak hujan lebat semasa dalam perjalanan ke PD tetapi alhamdulillah syukur kerana dapat pergi dan pulang dengan selamat.

Kami sampai ke PD lebih kurang jam 4.45ptg dan terus ke kaunter pendaftaran dimana kebetulan pula Kak Yong (9W2YZU) telah menjaga kaunter tersebut. Selepas pendaftaran, program seterusnya adalah sesi 'Technical Talk' disampaikan oleh 9M2DX. Agak terpegun dengan maklumat mengenai Propogasi/Propogation oleh beliau yang menunjukkan apakah yang berlaku disebalik wujudnya fenomena propogasi dan hubung kait dengan gelombang radio.

Thanks a lot.

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.

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!!!

Tahniah pada Komuniti V17 - Fox Hunt Selangor 2008

Syukur Alhamdulillah....

Sampai juga kami ke garisan penamat dalam satu kumpulan. Setelah mendapat beacon yang terakhir , kami memulakan larian ala-ala marathon ke HOME. Walaubagaimanapun apakan daya, baru sampai ke pertengahan jalan kami terpaksa mengalah kerana kurang stamina ( lidah dah terjulur sampai ke lantai woooo) , tapi nasib baik kami ada pelari pecut tanahair yang tidak sempat digilap bakat beliau kerana telah berkecimpung dalam radio amatur iaitu 9W2SMF. Dialah yang pertama sampai ke HOME sambil kami menyusul dibelakang berlari mengejar beliau. Apa yang saya boleh katakan padanya...laju woooooo...sambil tarik nafas sedalam2nya...tapi macam tak cukup. Dari jauh kami lihat ramai berada di HOME dan beranggapan...kami ke yang terakhir ni?

Larian 1000 langkah 9W2SMF

Rupanya kamilah kumpulan yang pertama (V17 B) sampai ke HOME pada jam 11:20 pagi. Lebih kurang 1 jam 5 min dari waktu pelepasan. V17 telah menghantar 3 kumpulan bagi menyemarakkan lagi pertandingan ini. Menang atau kalah bukanlah pengukur sebenar tetapi semangat ham perlu disemarakkan pada diri setiap rakan agar kesinambungan hobi ini akan dapat memberikan manfaat pada generasi akan datang.
Ribuan penghargaan kepada penganjur (MARTS), penasihat/penaja V17 (9M2RS), Ketua strategi (9W2SQ) dan penaja baju (9W2AMR), 9M2RZL dan rakan lain yang turut membantu dalam menjayakan program ini. Disebabkan penulis sendiri turut serta, gambar tidak sempat dirakam secara peribadi tetapi dirakam oleh jurugambar profesional semasa acara tersebut.

Tidak lupa juga takziah buat 9W2SMF atas kehilangan ayah beliau sehari sebelum dan tabik buat PARTS kerana menghantar wakil bagi sama-sama memeriahkan acara ini.
Rakan2 dari PARTS (Perak Amateur Radio Transmitter Society)

Apapun , selepas ini wakil V17 akan sentiasa menghantar wakil ke acara ini sekiranya dijemput InsyaAllah.

FOX HUNTING - ADA BERANI???

Fox Hunting atau ARDF ( Amateur Radio Direction Finding)




(Gambar diatas diambil dari blog jurukaka)

Bagi yang tidak pernah dengar apakah aktiviti Fox Hunting...maka bolehlah mulai bertanya pada rakan yang aktif dan giat dengan ham radio sekitar lokalan anda. Sebab aktiviti ini sukar nak digambarkan dengan kata-kata serta visual melainkan anda mendengar rakan yang pernah terlibat bercerita tentang permainan ini.

Untuk makluman rakan2, tak sampai sejam pun anda dapat siapkan antena yagi 3 elemen bagi tujuan fox hunting ini. Walaupun kelihatan mudah dan pelik bagi orang ramai lihat, tetapi jenis antena inilah yang agak berbisa semasa sedang mencari musang. Semasa latihan, ramai juga yang lalu lalang bertanya ....tentang aktiviti ini dan kebanyakan dari mereka memang kurang pengetahuan tentang radio amatur di Malaysia, bukan sahaja orang ramai malahan geng radio amatur sendiri pun tak pernah tau dan tidak ambil tahu.

Jadi...20hb ini pihak penganjur MARTS Selangor akan mengadakan pertandingan Fox Hunting di Tasik Titiwangsa. Ada kita dengar datang dari jauh untuk sertai.

Jadi...apa macam???? ADA BERANI kita berentap di sana cari musang!!!

Broadband Over Power Line memberi kesan terhadap Radio Amatur



Broadband over Power Line:

Why Amateur Radio Is Concerned about Its Deployment

What is Broadband over Power Line?
BPL is the delivery of broadband Internet signals using electrical wiring to conduct high-speed digital signals to homes and businesses. BPL systems are designed to deliver Internet services using medium voltage power lines as the distribution medium and generally use the frequency range between 1.7 and 80 megahertz (MHz) but for Malaysia range 1Mhz-40Mhz.

The Concern: Broadband + Power Lines = Interference
Because power lines are not designed to prevent radiation of RF energy, BPL represents a significant potential interference source for all radio services using this frequency range, including the Amateur Radio Service. Overhead electrical power lines and residential wiring act as antennas that unintentionally radiate the broadband signals as radio signals throughout entire neighborhoods and along roadsides. Interference has been observed nearly one mile from the nearest BPL source.


What is the status of BPL?
From a regulatory standpoint, BPL is an unlicensed, unintentional emitter of RF energy and is subject to FCC Part 15 rules. FCC rules require that BPL systems may only operate subject to the express condition that harmful interference is not caused to licensed radio services. BPL is not entitled to protection from interference. So far, BPL has been deployed in numerous temporary test sites but in few commercial installations. Despite the very limited deployment, considerable interference has been documented. In October 2004 the Federal Communications Commission (FCC) adopted new rules for BPL systems. These rules place new restrictions on BPL systems in recognition of the fact that they pose a greater threat of radio interference than most Part 15 devices, such as garage door openers. However, the new rules are not sufficient to reduce the probability of harmful interference to reasonable levels. Administrative appeals of the rules have been filed and court challenges are likely.


Why are the regulations inadequate?
The Communications Act of 1934 and the FCC Rules have long required that unlicensed emitters such as BPL systems must protect licensed radio services from interference, and that they must accept any interference to their operation that is the result of normal activity by licensed radio services. However, in practice it is often difficult to resolve such interference problems in the field. In one case in Cedar Rapids, Iowa, BPL engineers spent 12 weeks trying to solve an interference problem without success. The interference did not cease until the test was terminated prematurely.
Studies by the National Telecommunications and Information Administration (NTIA) show that the probability of interference from a BPL system operating at the FCC radiated emission limit on the same frequency as a typical two-way radio station is essentially 100% 200 to 400 meters from the power line, depending on the frequency. Despite this clear evidence that the limit is too permissive, the FCC declined to impose a tighter limit except in frequency bands used by aeronautical services. This means that unless they voluntarily design their systems for reduced emissions, BPL system operators will have to take expensive, customized steps to correct interference on a case-by-case basis. That may not be possible unless they turn off their systems. Of course, they will strongly resist having to do so. This is why radio operators are so concerned, and why BPL customers cannot be assured of receiving reliable broadband service.

Has the interference potential been proven?
The ARRL laboratory has made observations of BPL radiation at a number of trial areas. The lab's findings of interference and related information, including video and audio recordings of actual interference, are available on the Web at www.arrl.org/bpl. These and other observations of radio-frequency interference at BPL test sites in the US are a matter of public record in FCC files.
An April 27, 2004 report released by the NTIA acknowledges that BPL signals "unintentionally radiate" from power lines. The NTIA also said then-current FCC Part 15 measurement techniques may "significantly underestimate" peak BPL field strength and that "interference risks are high under existing FCC Part 15 rules." The FCC rulemaking only partially addressed these concerns.
Although BPL proponents dispute these claims of interference to licensed services, they have provided little in the way of calculations or measurements of BPL radiation levels -- and what they have provided has been flawed by technical errors.
Others at risk
The "short waves" -- the only part of the radio spectrum that supports long-distance, intercontinental radio communication. The short waves are used for international broadcasting, aeronautical, maritime, disaster relief, and other services including the military.
The "low-band VHF" frequency range that is heavily used by volunteer fire departments, police, and other first responders.
Depending on their distance from a BPL system, some public safety and federal government radio systems could receive harmful interference.

DXing Bagan Lalang

Its never been to late for me to congratulate V17 and elmers who willing to share their knowledge on how to operate and setup HF. Last minute i was not able to participate due to uncertain family problem. Really sorry guys because i was so jealous with u all.

Even though they are some negatives comment on those activities BUT we do take it positively purposely for the sake of ham radio. I will not making a noise or express my dissatisfaction for something are not worth to talk anymore. BUT please bear in mind my beloved friends, what is Radio Amateur? What is the unique about this kind of hobbies? Ask yourself on your contribution towards Radio Amateur development?

"To be or not to be.....tepuk dada tanya nak apa? .....no need to comment further.

I was so happy to be in this family...aren't you?????????

Semput dan demam panas

Kali ni coretan mengenai anak saya yang kedua berumur 9 bulan. (Muhamad Yusuf)
(Minta maaf keluar tajuk radio sekejap.)
Masuk hari ini dah 2 hari beliau terlantar di hospital Ampang kerana masalah kesukaran bernafas. Baru sahaja selesai menguji litar VOR ( Voice operated Relay) untuk sebarang kegunaan berkaitan radio dan elektronik. Alhamdulillah berjaya sehari sebelum beliau dimasukkan ke wad....ada kelapangan saya akan uploadkan setelah kesihatan sekeluarga mengizinkan.



Kesnya bermula apabila harmonic saya sukar untuk tidur , mengalami batuk berkahak dan demam panas. Setelah mendapat nasihat dari Klinik Kita Desa Pandan, doktor bertugas mencadangkan agar dimasukkan ke hospital untuk rawatan lanjut kerana jika simptom sukar bernafas dan hadapi demam panas cecah 38.5 , maka mungkin ada masalah dengan saluran penafasan dan paru-paru.



Setelah dilakukan X-ray dan ujian darah juga mendapati darah juga telah dijangkiti dan terus ditahan di wad sehingga waktu ini. Alhamdulilah setelah diberikan nebulizer, bayi dalam keadaan selesa dan mudah bernafas. Cuma selera minum dan makan agak berkurangan sedikit. Apa yang paling tidak sangka, saya juga ditemani oleh 9W2JEK dan 9W2MIG yang kebetulan berada sekitar sana sepanjang proses pemeriksaan awal sehingga ditahan di wad. Terima kasih kerana sudi menemani saya walaupun tidak berkesempatan ingin berbual panjang dengan 9W2MIG yang baru dikenali.



Diharapkan dengan sokongan dan doa rakan2, anak saya cepat sembuh dengan izin Allah swt. Amin dan Alhamdulillah.

Change your voice/audio

Salam to all,

Well....it is been a long time i'm not made any posting and updating on any of my projects or :) curiousity. After PRU12, i was a bit busy attending courses at KUB.COM and this is cumpulsory for a staff Telekom like me. Wow, technologies nowadays made me impressed....you all had witnesses that by using Yahoo Messenger u would able to communicate and talk freely without worrying a telephone bills.. ...well.....this is call technology innovatives.

But we are still holding and sticked to amateur radio as we do realize that without knowing basic telecommunication , we will not able to understand further ....

Lately, i was very happy that a lot of ham member were truly made a fun of their voice thru air...the echo sound made them very special and it is to show that....we are not a common ham members but learning something by doing an electronic circuits connected to their HT or RIG and heard your own audio sounds funny will encourage themselves to learn more and more.

Even if you do not know what is resistor and how it looks like, but believe me....by doing a simple electronics project will make them know better...:)...

Voice Changer using computer software

My first intention was to develop a voice changer electronic circuits which will change your audio to vibrato, echo , robot and pitch effects. But its hard for me to find 'IC WIN8072' which are important component to make the circuit function. Try to find at Jalan Pasar but u know....they even never heard of it. Well....jeng..jeng..jeng...if i couldn't find it ...why not i try it using software...more function and more cheaper. I've tested and it works fine. These are the step i would like to share:

1) Know your RJ12 pin for MIC,PTT and GND. (Yaesy FT8800 - Pin 4/GND,Pin6/PTT,Pin5/MIC)

2) Surf this website to develop electronic diagram from your PC to Radio (Refer Circuit 1)
http://www.eqso.org/faq/ptt-Interface-Circuits.htm this is to control your MIC sensitivity.

3) Download and install http://funny-voice.en.softonic.com/ (u may try other software- no harm)

For me it was very simple.....but my advice is...do learn the component well because some of it do have a polarity +ve and -ve....be aware of it or the end results may disappointed u. Okey...good luck and have fun.

Science is fun, so with the electronics. :)


For reference if u're using it. (Click Below)
http://www.datasheet4u.com/html/W/I/N/WIN8072_Winlead.pdf.html

Thanks for 9W2MZY for gives me a hope to get those IC WIN8072. If u found it....call me yahhh.

Antenna Analyser

Salam buat semua,

Malam tadi (5/2/08)agak menarik perbincangan di simplex V17 dimana topik perbualan berkisar mengenai 'Antenna Analyser'. Walaupun perbincangan agak lewat menghampiri tengah malam tetapi keseronokan menimba ilmu bukan mengira waktu. Terima kasih kepada 9M2RS (Hj.Rashid) ,9W2END (Firdaus), 9W2TPT (Hamid) yang sudi berkongsi pengetahuan.

Hasil dari perbincangan malam tadi, sedikit sebanyak saya memahami apakah kegunaan antenna analyser. Dari apa yang saya faham, kelebihannya agak banyak berbanding meter SWR biasa di mana salah satu fungsinya ia dapat mengukur 'Cable Losses', 'Distance to fault', 'Measure capacitance and inductance, ' Freq counter' dan sebagainya bergantung kepada pengeluar/manufacturer. Macam biasa, lagi banyak fungsi lagi mahal harganya. Apa yang menarik minat saya adalah kita tidak memerlukan tranceiver untuk menguji antena dimana 'Antenna Analyser' ini boleh beroperasi hanya dengan kuasa bateri dan bekalan kuasa dari luar. Pada pendapat saya kegunaannya mudah berbanding meter SWR biasa yang memerlukan power input untuk ujian.

Pada malam 6/2/08, kami iaitu 9W2TPT dan 9W2END telah eyeball dimana setiap perbincangan dari awal jam 10 mlm sehingga lewat jam 12 tgh malam adalah berkisar mengenai teknikal ham radio. Dalam masa yang sama juga 9w2TPT menjalankan demo mengenai fungsi 'Antenna Analyser MFJ-259' . Setelah diteliti memang sah, kegunaannya amat mudah sekali disamping mudah dibawah kemana sahaja.

Apa yang kita boleh dapati dari MFJ-259 ini adalah:

  1. Resonan frekuensi antena anda

  2. Tune/penalaan antena di atas tower tanpa perlu tranceiver dan menyaksikan perubahan SWR setiap kali melakukan penalaan.

  3. Tune antena mobile HF dalam masa beberapa saat sahaja.

  4. Ukur SWR antena

  5. Ukur induktan, kapasitan, resonan frekuensi, transmission line faktor velositi/impedance/loss.

  6. Uji RF chokes, transformer/alatubah dan balun.

  7. Trim antena sehingga SWR 1.1 tanpa perlu lakukan QRM.

Terima kasih pada 9w2TPT kerana sudi berkongsi penggunaan antenna analyser MFJ-259 ini. Pada pendapat saya, peralatan seperti ini penting kerana selain dari pelbagai fungsi ianya juga dapat membantu kita melakukan penalaan yang optimum terhadap antena yang digunakan.

Private QSO

Assalamualaikum wbt and very goodday to all,

Just a few days ago, i'm wondering weither my ICOM 2200H able to QSO in private with other station like scramble audio such as Motorola and Spender product . The other station monitoring might sense a signal but no audio being heard. So i started to explore my manual instruction handbook in order to get the full picture of its capability and compatibilty of what are the real function of :
  1. CTCSS tone encoder
  2. CTCSS tone encoder/decoder
  3. DTCS tone encoder/decoder

Can we use this function to QSO in private? .......

CTCSS tone encoder - normally you are using it to access repeater because you need to set TONE such as 103.5 , 203.5 or else . Repeaters will give access when you're transmitting the right TONE and the right shift +/- of course.

CTCSS tone encoder/decoder - Nor like CTCSS tone encoder, both or group members set the same tone for Tx Tone and Rx tone. The other station may heard your audio, but they are not able to join in because you have setting the tone for Rx which not known by others. This function is useful when you're not allow someone else to interfere between your conversation in group.

DTCS tone encoder/decoder - This function is a bit advance compare with CTCSS, it is stands for Digital Tone Code Squelch. It will open squelch/tone when receiving a signal
with the same pre-programmed subaudible tone or DTCS code, respectively. So in theory, other station may not heard any audio from us. It is not been tested yet of how does its really work and is it really .....PRIVATE?...hahahaha.....do we need to use it.?..and why?

It is called DCS for yaesu Ft8800 for information.

I'm keen to know from you guys, please throw your comment/experience here and hopefully we can fully know how to operate well our rig/HT. That's why we are called station and it is need to be operated by...... . And who are you if you can't operate your own rig/Ht?????

Next...we will discuss on a digital function and can we link up using the internet gateway?

RG213 vs RG214 Coaxial cable

Last night on freq 145.2125mhz (V17), we(9W2YED,9W2TLB,9W2SNA,9W2POK) had a discussion on air regarding on RG214 coaxial cable. Special thanks to Talib(9W2TLB) for brought up this matter. Most of us commonly use RG213 and physically saw how it looks like BUT what about RG214.........? What are the differences between RG213 and RG214?

RG213 (right picture) is low loss cable with a non-contaminating jacket.
General Specifications
Outer Diameter: 0.405 inches
Center Conductor: Stranded
Impedance: 50 Ohm
Outer Conductor: Braid
Velocity of Prop. :66%
Jacket: Black PVC-IIA

RG214 (right picture) is low loss cable with double braid and non-contaminating jacket
General Specifications
Outer Diameter:0.405 inches
Center Conductor: Stranded
Impedance :50 Ohm
Outer Conductor :Dual Braid
Velocity of Prop.: 66%
Jacket : Black PVC-IIA

Just look at it, the only different is the outer conducter (shield) whereby RG214 using dual Braid compared with RG213. I'm not sure the result of using RG214 technically because we're more common to use RG213 and easy to get at open market.

Please comment.

Tips of how to make the perfect solder joint



  1. All parts must be clean and free from dirt and grease.
  2. Try to secure the work firmly.
  3. "Tin" the iron tip with a small amount of solder. Do this immediately, with new tips being used for the first time.
  4. Clean the tip of the hot soldering iron on a damp sponge.
  5. Many people then add a tiny amount of fresh solder to the cleansed tip.
  6. Heat all parts of the joint with the iron for under a second or so.
  7. Continue heating, then apply sufficient solder only, to form an adequate joint.
  8. Remove and return the iron safely to its stand.
  9. It only takes two or three seconds at most, to solder the average p.c.b. joint.
  10. Do not move parts until the solder has cooled.

What is the phase reversal phenomenon significant in line-of-sight reception




In case of line of sight reception, there are two components of the signal. One is the direct signal and other is the signal reflected from the ionosphere. Both the signals leave the antenna with the same signal phase, but travel different paths to the receiving antenna. These paths may be of different length. Because the reflected signal suffers 180 degree phase reversal at the point of reflection, the two signals may aid or oppose each other in the receiving antenna. The resultant signal may be stronger or weaker than the direct path signal alone which is not desirable.
