Icom IC-706 Mk IIG






Assalamualaikum, kali ini saya kembali lagi dengan satu lagi rig,bukan baru atau lama, tetapi masih lagi diminati ramai. Icom IC 706Mk IIG. All band/all mode, seperti juga Yaesu FT 897D, cuma bezanya yang amat ketara, ianya tidak mempunyai compartment bagi bateri, dibandingkan dengan saiz nya yang agak compact,sesuai sekali bagi aktiviti 4x4 dan aktiviti luar yang lain. Ianya boleh ditambah dengan lain-lain aksesori seperti AH-4 Automatic Antenna Tuner + 50Mhz covers 3.5Mhz - 54 Mhz with 7 Mtr ( 23 feet)@ longer wire antenna dan AT 180 + 50 Mhz. jadi , buatlah pilihan yang sesuai dengan keperluan anda....!

hand free PTT


assalamualaikum, kali ini saya inginkan pendapat rakan-rakan mengenai kit hand free PTT. sebelum nie kita pernah mendengar ada dikalangan rakan Ham telah di saman atas kesalahan menggunakan alatan komunikasi, Rig mobile atau handy, semasa sedang memandu. Alasan tersebut dikukuhkan lagi dengan menyamakan penggunaan apparatus radio@ rig dengan pengguna handphone. Hakikat sebenarnya , hanya pihak berkuasa, yakni Polis ,tentera JPA 3, Ambulance serta Pihak Bomba saja yang dibenarkan berbuat demikian atas dasar tugas @ kecemasan.Oleh itu, rakan-rakan perlu mencari alternatif lain, seperti cuba mendapatkan @ membuat sendiri PTT seperti kit handfree untuk pengguna handphone. disini saya ada sertakan contoh head mic, jadi rakan-rakan perlu mencarinya ikut kesesuaian sendiri. selamat mencari dan mencuba, 73

Vintage Radio/Emergency Beacon



Hi all, this is special and vintage military radio. This radio often to be a lifesaver for pilot if they manage to survive from helicopter crash. This equipment known as Sarbe 5 (Search And Rescue Beacon). When activated, the unit transmits a continuous internationally recognised swept-tone radio distress signals in the UHF or VHF aviation frequency band. It also provide two-way voice communication between the survivor and approaching rescuers. Built in 'test' facilities allow a simple confidence check to be carried out for correct functioning of the unit and the battery state.
The Sarbe is waterproof to a depth of 10m (33Ft)and the battery has an unused shelf life of 5 years when stored in continuous temperate conditions.That's all, for the Vintage Radios Review. and i, will bring much more enjoyable info,s for next reviews, See you all guys, 73

Yaesu VX-170


Kecil-kecil cili padi, itulah ungkapan tepat bagi si kecil, tidak lain bukan, ialah, Yaesu VX-170, Bagi rakan-rakan Ham yang gemarkan aktiviti lasak, inilah salah satu pilihan yang bijak untuk memilikinya. Dengan ketahanan kalis airnya, dan binaan dari kerangka logam, serta paparan cecair kristalnya (LCD) yang besar serta mudah untuk dikendalikan, menjadi topik Rig pilihan saya untuk kali ini. Bagi yang pernah menggunakan rig ini,dari komen rakan-rakan rapat saya, menyatakan bahawa Rig ini mempunyai keistimewaannya tersendiri.
Pernah salah seorang rakan saya sendiri memberitahu bahawa kualiti pemancaran Rig ini amat mengagumkan,hanya dengan "basic setup " menggunakan cable RG 58 dan Antenna Daimond MC 101,dan menggunakan Magnetic Mount yg diletakkan pada tengah bumbung kereta.
