WebSDR de W4AX

A WebSDR is a Software-Defined Radio receiver connected to the Internet, allowing up to 40 users to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet.

The antenna is a Clifton Labs Active Antenna. The 160M antenna is an Inverted L with the L at 30 meters high.

The antenna plugs into a Clifton Labs DC Power Coupler to provide power to the antenna.

The Power Coupler connects to an RF Input Limiter to prevent destroying the pre-amp when using my legal limit amplifier. I can't get the WebSDR antenna out of the RF pattern of my ham radio stations antennas so it is important to protect the front end of the pre-amp. (note: there will be disruption of received signals when I transmit.)

The next stage is a Clifton Labs Norton Pre-amp which has a +11 dB gain from 100 KHz to 30 MHz.
This stage in the chain then feeds a 1 to 3 RF splitter. This device maintains a 50 ohm input impedance to each of the receivers and provides isolation between ports to minimize receiver local oscillator interference. The penalty is a 5 dB insertion loss. At this point in the chain there is an overall +6 dB gain on the signal going to the receivers.

Finally, the signal is received by four separate Tony Parks, KB9YIG SoftRock Lite II receivers on 160M, 80M, 40M and 20M. These receivers convert the RF to I & Q signals to be processed by the WebSDR software on the computer. Their performance is amazing considering they cost $20 USD each.
My WebSDR server consists of a PC running Ubuntu and the WebSDR server software. It is a quad core processor with 12 GB of RAM. Sound cards are three ASUS Xonar D1 and the motherboard Creative Labs sound card all at 192 KHz sample rate. To accommodate 40+ users an Internet connection with 40 Mb of upload bandwidth is used. Each user connection consumes about 200 kb of upload bandwidth.

9W2GND uji pancar dari Masai Johor Bharu di 9M4RBC

Malam tadi lebih kurang jam 1.55 pagi kedengaran audio 9W2GND dari Masai, Johor Bharu menguji pancar ke 9M4RBC 147.750MHz. Antena setinggi 40 kaki dan kuasa pancaran 50 watt telah berjaya memancar ke repeater di Genting. Mungkin malam tadi propagasi sangat baik membolehkan memancar terus ke kawasan tengah.

Field Day

The fourth full weekend in June is ARRL Field Day. Radio amateurs in the United States and Canada are encouraged to set up portable stations running off emergency power to stimulate operating under extreme conditions. Field  day is not really a contest but an emergency-preparedness exercise that has a contest-like operating experience. Many of  today's big gun contesters cut their teeth at Field Day.
        Many Field Day operations are run by radio clubs; however, some may be run by one or two individuals. Fields Day can be the highlight of a club's operating events. For some clubs, Field Day is a picnic with some operating thrown in. Other clubs put up large towers with Yagi antennas and set up in a public space. Each group does it differently, with many trying to compete with others within their own operating expertise, antenna setup and placement,  power distribution, lightning portection, computer logging, CW and voice HF operating, digital modes, gastronomical delights, and other area of amateur radio

Portable di Melaka

Pada 2 Jun yang lalu aku menukar program ke pantai timur  tukar ke Melaka bandaraya bersejarah bersama xyl pada saat-saat akhir atas sebab-sebab yang tidak dapat dielakkan. Jadi terus memandu ke Melaka dan tiba pada petang itu melalui tol Ayer Keroh terus ke Banda Hilir. Banyak perubahan dapat dilihat di sini dengan pelbagai projek pembangunan tanpa merosakkan tinggalan sejarah. Dataran pahlawan telah merubah landskap padang menjadi sebuah kompleks membeli-belah. Jadi aku berjalan-jalan selepas check-in di sebuah hotel di situ. Berjalan-jalan disekitar kompleks membeli-belah tanpa ke tapak warisan dunia memandangkan hari semakin lewat petang. Selepas makam malam kami berdua ke river cruise di sungai Melaka.Tambang seorang RM10 perjalanan menaiki bot dari jeti Muara ke Taman Rempah memberi satu keseronokan dengan pemandangan sekitar sungai sangat menarik. Melalui kampung Morten dengan keindahan senibina rumah melayu tradisi di kekalkan untuk tatapan generasi. Selain itu melintasi beberapa batang jambatan yang mempunyai sejarahnya yang tersendiri. Hampir 45 minit perjalanan kembali semula ke jeti yang kami naiki tadi. Selepas bergambar kenangan terus  ke hotel penginapan terletak berdekatan dengan Jetty.
Portable di tingkat 13 memberi aku peluang yang luas untuk monitor mana-mana jalur di Melaka ini.Seperti biasa menggunakan handy dengan antena rubber duckies memantau mana-mana frekuensi. Cuba-cuba simplex 145.400MHz memanggil mana-mana rakan telah dijawab oleh 9M2TRX radio operator Kamarul di basenya Kg Gelam. Sebenarnya aku QSO di hamsphere sehari sebelumnya tak sangka pula bersimplex bersamanya.
Kemudian monitor 147.700MHz Jasra kedengaran beberapa rakan sedang monitor seperti 9W2LCM, 9W2LXN, 9W2BIZ dan YF5VTR. 9M4RBC juga dapat diterima dengan baik 5 9 dan juga semua jalur komersial di pengulang  Genting Highlands.
Keesokkan paginya aku kedengaran rakan bermobile QSO iaitu 9W2ZNL dengan 9W2KRT. Abg Zainal 9W2ZNL sedang mobile ke Port Dickson melalui Sg Udang ketika itu manakala Abg Sharil atau karat baru pulang dari saltmine ke base di Batu Berendam. Apabila mereka berdua tidak dapat lagi copy dan QRT aku cuba memanggil dan dijawab oleh karat dicopy dengan baik 5 9. Jadi dapatlah salam contact kenal di udara. Ada kelapangan dan kesempatan boleh QSO lagi jumpa dan jumpa lagi. Selepas itu aku breakfast bersama xyl dan pulang semula ke bilik selepas itu sambil monitor sebelum check out jam 12 tengahari.
