80m Band

Today evening i have short eyeball with Aziz (9m2one), he came to my QTH, we talk a lot about hams..suddenly, he talk about he want to life 80m band at Malaysia..i really highly appreciated he intent on that..then, i agreed 100% on that..because so far i didn't play at that freq anymore..huhuhu..so, with this little goods, i really hope many hams from 9M can give support to life back 80m Band at Malaysia..may be one day, i will update to give the freq on 80m Band..

Freq: 3.860mhz & 3.895mhz

long life to 80m Band, 73 from 9M2ODY

Antenna Book

First of all, i would like to say thanks to Fadzil (9w2xz), who person have gave me this book..a lot help me in-doing homebrew antenna including calculation, coil trap etc..after he gave me this book, i learn many things about antenna, radio, cable, calculation etc..nevertheless, if not possible to buy this book right now because i didn't find any sources..on top of that, he give me as gift because he told me he don't want to play radio anymore, he said want retired already..don't know how far the truth..he..he..anyhow, thank for this present..

Grounding

salam & see again my Dear..

i would like to express my thanks to Tango (9m2np), who give me a lot of idea/knowledges from his experiences for this earthing, from how to find the Silence earth until found it..so now, i would like to share with u about his idea..this happened from our freind from Singapore (9v1jy) live at 15th floor of Apartment, then he have no idea to find grounding..then Tango give him idea to put grounding onto wall..at the 1st time i heard, quiet surprise me but after he calobrate further, then i know that wall also made from Sand, Ground, Clay etc..all this thing2 have at Earth..but must be remember that, only wall use Red Solid Brick can get the proper grounding..cause today a lot developer make house from White Brick & Hollow brick..so, better check ur house, which one use..hehehe..for my 1st grounding, i punch direct to earth using Copper Rod, then after Tango give me idea about this..so i change it..according Tango, my 1st grounding is too far from my rig..which mean it not well-working at all..grounding must be close as u can with the set/radio..gud luck my Dear..

Wall plug (if can get Copper one is better)

my 1st grounding (punch direct to earth) - about 30' to my rig

after change location (punch onto wall) - only 2' from my rig

Luck

may be yesterday (18/12/09) & today (19/12/09) are my lucky day, what happenned are i got a lot contacts station from VE, LU, KH6, CP etc..the time is arround 9am MST..my yagi beam point to west..all stations copy me 57/58..my RF power is 95w..huhu..all station asking me "why not push to barefoot 100w" i said "don't want because i luv my rig" huhuhu..everybody asking about my working condition, i said "my antenna height about 20' from Grd. level & my rig is TS-570D"..every station wonder how come from that height i can reach there..for me, may be propagation & modulation at that time well-open..so, just think to accept it..ha..ha..really want to try again by tomorrow morning & try to get more & more station from west..gud luck my dear..

Tribander Dipole - Homebrew again

Today i have time to make this antenna again..after DAL convinced me to make this antenna..i make 2sets..1set already booked from our member from northern of peninsular Malaysia..got another set readymade open for any kind of members want to try this antenna..after completed, tested with swr meter..the results at 40m & 20m are 1:1.7, at 10m is 1:2..so, at 40m & 20m band no need tuner because 1:1.7 are still acceptable to use..for 10m need to use tuner..this idea coming because of the area, in certain extend, our area doesn't sufficient, so this is the suit antenna..one more thing is Portable antenna..this antenna design purposely for those want to set up Portable station like at village, trip field day etc..

Grounding & Propagation

Kedua-dua ini amat penting untuk membuat panggilan jauh (CQ DX)..ini kerana gelombang atau 'wave' semestinya akan membuat satu pusingan (loop)..jika anda biasa dgn dxing sudah pasti rata2 rakan hams yg berada diluar sana menggunakan 'liners' atau 'kasut' yg RF kuasa (power) antara 300w-1.5kw..ini sudah pasti anda rx audio rakan tersebut dengan S-9 +40db..meskipon jauh beribu batu mereka tx..power tersebut sudah cukup untuk 'cover' satu dunia..ini bagi mereka yg mempunyai 'pulus' yg lebat sudah tentu takde masalah..bagi mereka yg minat utk dxing dgn hanya 5-30w sahaja sudah bleh sampai ke US (W or A station), grounding amatlah penting..ini kita kenali sebagai 'QRP Station'..meskipon kadang2 kita tx dgn 'barefoot' 100w, mereka yg berada di US menggelarkan kita 'QRP Station'..he..he..agak kelakar kan..? dh itu jer power yg mampu rig kita tx..huhu..lain la kalau ade 'kasut'..dengan input 5w dari rig, power yg keluar dari 'kasut' boleh mencecah 300-450w, bergantung pada 'kasut' tersebut..ade rakan daripada JB, dengan menggunakan FT-817ND, yg rakan2 semua tau ini merupakan set HF QRP..5w sahaja dia sudah bleh pegang Australia (VK Station)..rakan dari Australia td tx dgn 500w, RST diterimanya 58..not bad..ini kerana kajian perlu dilakukan untuk mencari 'grounding' yang baik..terdapat 2 jenis 'grounding' iaitu 'Noise Earth' & 'Silence Earth'..jadi pastikan anda jumpa 'Silence Earth'..ini merupakan 'grounding' yg terbaik..

Baru-baru ini, saya telah mencari 'grounding' yg terbaik berhampiran base saya..tanah pon ade 3'/segi jer..rumah teres..huhuhu..dengan menggunakan 'copper rod' dan juga wayar 1.5mm..hasilnya, Alhamdulillah..dengan bantuan antenna 'simple homebrew g5rv' dengan kuasa 15w, saya dapat berQSO dgn VK & V88 stesen yg mana masing2 terima RST:58..errmmm..not so bad..
