CQ or CQDX must only be used ON A CLEAR FREQUENCY.

*** CQ or CQDX must only be used ON A CLEAR FREQUENCY.***

There seem to be many operators who will reply to a call or try to call into an ongoing QSO on an already occupied frequency with ‘CQ CQ’ and then their call sign. This should NOT be done..

CQ and CQDX calls MUST only be used on a CLEAR frequency…

When replying to another stations CQ or CQDX call you do NOT say CQ or CQDX back, you should say your Call Sign only ONCE, that is all that is needed.

When You have transmitted your call sign, WAIT for the other station to call you in to make contact. There may be other stations also replying to their call so you must listen for them to call you (or another station they have heard) in to make contact..

All information other than your call sign can wait until you are called in for contact.

When you are called in for contact that is when you can give Signal report, Operators Name, location and any other information.. —

CQ or CQDX must only be used ON A CLEAR FREQUENCY.

How to use Propagation Predictions

** Handy Notes for HamSphere 4 Operators ** – Propagation

Following the propagation is possibly the most important thing to learn when using HamSphere 4 or ‘Real world’ HF radio equipment as It will enable you to know which bands will give the the best chance of hearing contacts in any particular part of the world, and of course this will give any stations in that area the best chance of hearing You calling!

Question:- How do I know which is the best band for me to use ?

Answer:- Being on the Best band to make a contact depends on four main factors…Your location, where in the world you want to make contact, Propagation and Time..

The best way to be on the right bands at the right times is to look at propagation predictions from Your location. This will allow you to see which bands are open from your QTH into different parts of the world as the day (or night) goes by. — The example image below shows propagation for today from My QTH in Scotland (IO75sj) into Latvia. (Using VOACAP online ”http://www.voacap.com/prediction.html”)

Example Image: Propagation into Latvia from Scotland

Example Image: Propagation into Latvia from Scotland

– If I wanted to make contact with stations in Latvia at 18:00 UTC  I would be best to try calling for them on 40m, 60m, or 80m bands and would have a reasonable chance of contact on 30m band. — But If I wanted to make contact into Latvia and I was only going to be on the air from say 10:00 UTC until 12:00 UTC I would be best to try calling for stations in Latvia on 15m, 17m, 20m or 30m bands. — And if I was to going to be on air from 22:00 UTC until 00:00 UTC calling on 15m, 17m, or 20m would be pointless as there is no propagation from My QTH into Latvia on those bands and 30m would be possible but not as strong at 60m and 80m bands, So I would be best to use 60m or 80m bands to make contact into Latvia at that time. -

How to give a proper Signal Report.

Signal reports are normally reported as using R S T This refers to ‘R’eadabilty ‘S’trength and ‘T’one When operating in Phone Mode (Voice) it is normal practice to report only the Readability and signal Strength. Readability is reported using the following ‘scale’

1 = Unreadable
2 = Barely readable, occasional words distinguishable.
3 = Readable with considerable difficulty.
4 = Readable with practically no difficulty.
5 = Perfectly readable.

So a perfectly readable voice reception would be reported as a ’5′. If the received voice is maybe quiet or has a little noise along with it but is still readable and all words are still understandable you may give a reading of ’4′. When you are having trouble making out what the transmitting station is saying but still hearing enough to just make out what they are saying with a fair bit of difficulty you would report a ’3′ etc..
Signal strength is usually read from the S-Meter. EG: Looking at the LEFT S-Meter shown below: You are receiving a station and you can make out all that they are saying but the audio is not ‘Perfectly readable’ due to the audio being quiet or having some noise along with it you could report that their signal was 42 or 43 if the needle on the S-meter moved up to the ’3′ as they were speaking. Looking at the RIGHT S-Meter shown below: You are receiving a station ‘Perfectly’ with good clear clear audio you could report that their signal was a 55 or ‘five and five’ – If you are receiving them as ‘perfect’ audio and the S-Meter needle is past the 9, for example at the +20 mark, you would read the S-meter as 59 plus 20 dB. Of course if the audio was ‘Perfectly’ good and clear and the S-Meter needle was at the mark between the +20 and +40 you would report the signal strength as 59 plus 30dB. – The ‘T’ of ‘RST’ is for reporting the received signal Tone and is only used when reporting CW (Morse) signal reception. This is done according to the following scale with a range from 1 to 9 something like this:

1 = Sixty cycle a.c or less, very rough and broad.
2 = Very rough a.c. very harsh and broad.
3 = Rough a.c. tone, rectified but not filtered.
4 = Rough note, some trace of filtering.
5 = Filtered rectified a.c. but strongly ripple-modulated.
6 = Filtered tone, definite trace of ripple modulation.
7 = Near pure tone, trace of ripple modulation.
8 = Near perfect tone, slight trace of modulation.
9 = Perfect tone, no trace of ripple or modulation of any kind.

So when using Phone mode (voice) you only report the R and S as described above and you do not use the ‘T’one part of the report… Accurate signal reporting is an important part of radio communications procedure and It is very easy when you get used to it. I hope this helps operators to give correct signal reports..

Note about the ‘Custom Nameplate’ plug-in modules.

For those of You that have the ‘Custom Name Plate’ – Pop into the editor and you will find there is a new feature available on this plug-in module. – You can now select TWO colours for the text – one for Receive and one for Transmit.  See images below:- Upper image: In editor (RX colour displayed) – Lower image: On radio when Transmitting (TX colour displayed) – Very Nice! -

Custom Name Plate in Editor showing buttons to set text, font, shadow and select colours. The TX=RX sets both colours the same for those who do not want the text to change colour when you transmit.

Custom Name Plate in Editor showing buttons to set text, font, shadow and select colours. The TX=RX sets both colours the same.

For anyone who does not want the colour to change when you Transmit – click on the ‘TX=RX’ button when in the Editor, that will allow you to make the RX and TX colours both the same.

There is also a new smaller version available in the HamSphere 4 shop now. It can also be setup with 2 different colours for RX and TX modes.

DX Monitors and how to make use of them.

The HamSphere 4 DX Monitors are wideband receiver stations around the world that operate 24 hours a day, they ‘listen’ continuously for signals on all bands. To make use of the DX monitors you will have to turn on the ”DX mon” report feature using the button at the bottom of your ‘DX Monitor module’ on your transceiver. (see image below) When any DX monitor station receives your transmitted signal they will send a report to you that will be displayed the DX-Monitor module on your HamSphere 4 transceiver where you will see their report in Red text. They report their ID and Signal strength EG: [DXMON] AUE:S2, EUC:S4 ASE:S2 This shows that the DX monitors located in Australia, Europe and China are receiving my transmission at the signal strength shown after the DX monitor ID This gives a good indication of the current propagation conditions between your transmitter location and each of The DX-Monitors. The locations of the DX monitors are shown on the map below: – 73 de Hairy Paul 108hs5625

The Image below is the Current HamSphere 4.0 Band Plan – PLEASE replace your old HamSphere 4.0 Band Plan with this current version. :

Notification was posted on 2 April at 17:14 UTC
” As of today we will allow CW on all HS 4.0 bands except BC. Max 10 Watts carrier power below 10 MHz and Max 5 watts CW power above 10MHz. There are no frequency restrictions in place.” –
Please take note of the power restrictions, stick within the power limits and ‘You have the power to go forth and CW on All bands’ (except BC and 2m /70cm repeaters) – Enjoy the new frequencies !
