APRSDroid AFSK Test
سْمِ ٱللهِ ٱلرَّحْمٰنِ ٱلرَّحِيمِ
السَّلَامُ عَلَيْكُمْ
Sudah lama saya tidak menulis di blog kerana kekangan masa dengan urusan kerja. Hari ini perkongsian saya mengenai aplikasi APRSDroid dengan ujian aturan AFSK dari aplikasi tersebut.
Untuk memulakan ujian, antara peralatan yang diperlukan adalah seperti berikut:
- Aparatus Assignment (AA)/Penguntukan Radas bagi Radio Amatur yang telah sah dan belum tamat tempoh.
- Telefon pintar dengan versi android 2.2 dan ke atas serta mempunyai GPS binaan dalaman.
- Sebarang radio/walkie-talkie 5Watt.
- Kabel Audio 4pin TRRS ke Kenwood pin.
- Kabel RG58 50ohm with SO239 connector atau sebarang kabel yang sesuai untuk antenna.
- Antenna VHF 1/4λ atau lebih.
Untuk projek ini kita mulakan dengan membuat kabel audio untuk telefon ke radio. Untuk projek ini, saya memilih untuk membuat sendiri kabel tersebut. Kabelnya saya menggunakan lebihan kabel rangkaian dan untuk audio jack saya gunakan 1x4pin 3.5mm, 1x3pin 3.5mm dan 1x3pin 2.5mm. Gambar berikut adalah diagram kabel audio dan hasilnya setelah siap.
Seterusnya untuk telefon pintar perlu dilakukan pemasangan aplikasi APRSDroid. Aplikasi ini boleh didapati dari Google Apps Store atau dengan

Strange activity on 7020KHz
During SWL-ing on 40meter band, I have heard some strange activity where the operator were singing, laughing and transmiting music on amateur frequency but they never announce their callsign. So I decided to record some of their behaviour and hope to have some explaination from who know what is going on during that time of recording. I suspected it have to be some pirate a.k.a unlicense operator that operating on that frequency. It happen on 20 October 2017. Watch the video below.
