HF : How far u can go...


HF Band

Siang

Malam

(1.8mhz) 160m

(3.5 mhz) 80m

(5 mhz) 60m

1000 – 2000 batu atau

1600 km – 3200 km

Untuk dxing jarak jauh, sesuai ketika matahari terbit atau matahari tenggelam. 9,000 km keatas.

(7mhz) 40m

(10mhz) 30m

300 – 1000 batu atau

480 km – 1600km


300 – 1500 batu atau

550 km – 1800 km

(14mhz) 20m

(18mhz) 17m

Sesuai untuk dxing jarak jauh. Band 18m membuka pada atau sebelum dan selepas matahari tenggelam.

5000 - 10,000 km keatas


Band 20m selalunya membuka pada bahagian barat dan ianya 24 jam membuka.

7000 - 10,000km keatas

(21mhz) 15m

(24mhz) 12m

(28mhz) 10m

Paling sesuai untuk dxing jarak jauh.

( 8000 - 15,000km keatas)

Band membuka dari timur selepas matahari terbit dan ke barat pada sebelah petangnya.


Band tutup selepas 1 jam matahari terbenam. Kira-kira pukul 8 malam.

( 8000 - 15,000km keatas)


Kesimpulannya, semasa pertukaran waktu dari malam ke pagi, dan petang ke malam adalah masa yang paling sesuai untuk melakukan dxing jarak jauh kerana pada masa itu, ketumpatan electron di lapisan f2 adalah tinggi dan ianya akan memberikan jarak yang jauh kepada transmisi kita, Hanya 100 watt sahaja ia mampu mencapai jarak ribuan kilometer. Kenapa? sila lihat rajah ini.



Lapisan F2 bertindak seperti cermin apabila suatu isyarat radio seperti isyarat dari band 10 meter dipancarkan. Lapisan "F2" membalikkankan isyarat kembali ke bumi, dan selalunya ianya jatuh pada jarak ribuan kilometer dari antena kita.

Sebenarnya, signal-signal yang kita dengar telah "terpantul" beberapa kali antara "F2" lapisan dan permukaan bumi. Ini biasanya disebut "melompat" atau "skip" .

Ketika perkara ini terjadi, isyarat radio dapat dipancarkan antara stesen radio yang terletak ribuan kilometer jaraknya dan ianya adalah suatu perkara yang hebat bagi penggemar DXING.

SOALAN : Kenapa band 40m, 80m dan 160m kurang jarak TX nya dan kenapa band 20m, 10m jauh jarak TX nya?

Jawapan: Untuk memahami dengan lebih lanjut, sila lihat rajah di bawah...

Splits

video
9m2zak splits with 9g5tt

The terms split is used when a station is tx on one fre, but listening on another. this procedure is common when many stations are trying to get through to a single station, such as a rare DX station.

You can tell that a station is working split when you hear the station contacting other stations but you cant hear those station responses....

It can also work the other way around:sometimes you tune in a pileup of stations trying to contact a DX station but you arent able to hear the DX station responses.

Typically, the DX station is split listening fre is a few khz above the tx fre. The station being called gives instructions such as "listening up 5". The former means he is listening for stations 5 khz above his tx fre. Example, 14.195 to 14.200 khz.

To "work split", set one of your radio main tuning controls (called VFOs, which is means Variable Frequency Oscillator) to the tx fre and other to the rx fre. These usually referred to as "VFO A" and "VFO B".

Set up the radio to listen where one VFO is set and tx on the other. Read your rig manual carefully so that u do this properly. If u accidently tx on the wrong VFO, u interfere with DX station.

This method is the easiest way to working split, but it not the only one, u can also establish the tx and rx fre as memory selections on your radio, and then jump between memories. dont bother trying to dial back and forth, u wont be quick enough. With either method, practice for a while first, before trying it out on the air. Gud luck and gud dx.

Failing to make contact


But what if you to make a contact and your call doesnt get answered with a respond? Your signal may be too weak to hear or the station may have strong noise or interference that u cant hear. in this case, you find another station to call. assuming that your signaal is strong enough for another stations to hear it however, several other things may happened. this happen to my friend...see this
video and study it...

video
  1. Other hams are calling at the same time. you can either wait around until the station you intented to contact is free and try again, or you can tune around for another contact opportunity. the most important thing is not to get discouraged.
  2. The calling station can hear you, but cant make out your call. the hams may either ask you to call again or respond to you, but wont have your call sign correct. the station may say: "station calling, please come again." or " QRZed?" or "who is the station calling?"
QRZed? is the interntional Q-signal for "who calling me? Hams often use the British pronunciation, Zed, for the letter Z. At this point, just repeat your call 2 or 3 times, using standard phonetics and say, Over when you wish.

the station gets your call wrong by a letter or two. first stand by a few seconds to be sure another station with that call sign isnt on the same frequency. for example, 9m2zak and 9m2zae. then respond with : 9m2zak this is 9m2get ( repeat twice more), do you have my call correct? over

If repeated attempts at making contacts arent producing results, check out your equipment. the easiest way is to locate a licensed friend and have him or her make a contact with u. that way u know your transmitter is ( or isnt) working and your signal is understandable. if u dont have 9m2 friends, run through the following checklist to be sure you are tx what, when, and where you think you should be:
  1. Are you sure you are tx on the right fre? press the ptt or press the morse key, and wacth the radio display very carefully. the indicators for the fre and sideband should stay exactly the same. you may be tx on different sideband or fre than you think you are!
  2. Are you sure that your rig is producing power? wacth the rigs power output meter to be sure the output power varies along with your voice or keying.
  3. Is the antenna connected properly? You should be receiving signals that are moderate to strong, indicating 4 to 9 S-units on the radio meter. If the signal are very weak, you may have an antenna or cable problem. This problem also shows up as an SWR reading of more than 5:1 on your rig SWR meter.
after your call is received correctly by the another station, proceed with the rest of the contact. failed contacts and errors are handled very similarly on cw and digital modes. dont be BASHFUL about correcting your call sign. after all, its your radio name.
