Frequency Chart of most used Modes

________________________________________

These are the suggested starting frequencies for initiating QSOs.
As good operators you should be ever mindful of proper operating practice. No one owns a frequency, be courteous. If the frequency is busy slide up or down. This plan conforms to the newly released Considerate Operator’s Guide, published in the March 2007 issue of QST.
 
The following frequency are for region 2 and some maybe applicable to us in Region 3. To Harmonize the HF spectrum band plan for region 1, 2 & 3 we have to consider the following guidelines…

Note:

In 2006 The International Amateur Radio Union Region 3 Band Plan has been updated to include five emergency Centre of Activity (CoA) frequencies.
These are 3.600, 7.110, 14.300, 18.160 and 21.360 MHz. The move to adopt these frequencies made at the recent IARU Region 3 Conference, follows similar decisions at earlier IARU Region 1 and Region 2 Conferences.
CoA are not spot frequencies, but a starting point + or – 5kHz, are not the only frequencies to be used, and are not mode specific and should be considered as being ‘all modes’.

 
  1. Salam,
    terdapat novice/tech dalam post diatas. adakah ini dari ARRL ? adakah US masih ada kelas novice ?

    terima kasih.

     
     
  2. Saya tak pasti…tapi apa2 pun itu tak penting yg penting di sini ialah dimana boleh bekerja PSK31, RTTY, CW, SSTV, Telephony…yg digunakan supaya kita tidak tersasar atau bekerja di frequency dgn MODE yang tidak betul…

     
     
  3. Faizul…
    Terima kasih atas komen yang diberikan dan saya mengalu-alukan sebarang komen atau cadangan. Sebenarnya post di atas adalah garis panduan utk HF yang lain2 tu hanya sebagai bentuk pengetahuan apa yang dilakukan di Region 2. Untuk pengetahuan pembaca QST adalah majalah yang di keluarkan oleh ARRL jika kita menjadi ahli ARRL setiap bulan anda akan menerima majalah QST.

     
  4. terima kasih.
    sekadar bertanya, sebab setahu saya US telah drop novice kelas beberapa tahun lepas.
    setuju dengan pendapat anda,
    yang penting adalah garis panduan untuk HF bands.
    yang mana boleh diguna pakai mengikut region masing-masing.
    saya sendiri pernah ditanya “apakah calling freq untuk 80meter”
    saya tidak dapat menjawab soalan itu memandangkan saya masih mentah dalam radio amatur.
    QST dan 73 adalah majalah yang popular di US. amat susah kalau dicari sini. kalau 9M2AU ada koleksi, bolehla diphotostat nanti.

     
     
  5. Faizul…
    Ok tak mengapa kita sebenarnya dalam proses pembelajaran. Tak semestinya hari ini dapat AA kita tau semua. Yang penting kita harus mendalami “explore” apa yang ada di sebalik Ham Radio. Bukan satelah lulus ujian RAE kita campak semuanya ketepi. Ilmu amat penting utk kita semua. Dan jika ada Ilmu perlulah kita beramal. Cuba kita lihat di Region 2 spectrum nya lebih luas jika di bandingkan dengan region 1 & 3,

    Untuk pengetahuan anda QST magazine tidak di jual ianya di keluarkan untuk Ahli ARRL sahaja sementara RADCOM untuk ahli RSGB. Sementara majalah 73 pula setahu saya sudah di hentikan pengeluarannya. Kerana tidak mendapat sambutan. Sementara Practical Wireless, CQ magazine, Monitoring Times, Shortwave Listener masih ada lagi namun ianya amat sukar di perolehi di Malaysia, Ini kerana di negara kita orang2 nya amat gemar membaca majalah yang berbentuk hiburan, majalah yang berbentuk pengetahuan amat kurang pembacanya dan jumlah radio amatur di negara kita tidak lah sebanyak yang ada di Thailand, Jepun, Amerika, German dll.

     
  6. Untuk 2 meter ada tak freq COA untuk emergency bencana…

     
     
  7. 9W2MAX Untuk info setahu saya tidak ada COA untuk 2 meter. Setengah negara memperuntukan 145.500 CALLING FREQ. Sementara setengah negara pula 146.550 untuk National Emergency Frequency……..
