Your help needed

I am planning to create pages dedicated to user report of equipment they have purchased and are using/have used. This can be from Transceivers for HF, VHF be they bae, mobile or handhelds.  Antenna tuners either manual or automatic, Mobile aerials for VHF,UHF,HF. Antennas for HF,VHF,UHF for base, mobile and portable use….. you get the picture any piece of kit really.

To do this I need the site readers assistance.

Please take the time to write a short review and forward it to me via e-mail to g4usb.crac@gmail.com

I hope I will receive many responses as it will help to grow the resources of our site and provide useful information for our readers.

If reviewing an aerial please give brief details of the way it is erected, height of the pole, QTH height ASL etc as this will help our reader to judge the aerials suitability for them at their operating site.

Many thanks in advance.

Confusion over proposed ‘K’ prefix for Cornwall

Source The RSGB News extra service e-mail

The RSGB has received a significant number of enquiries expressing confusion and concern about the unexpected allocation of the secondary prefix “K” for Cornwall.

As a result, the Board has written to Ofcom asking them to review their decision and consult on the changes that they are proposing.

Amateur Radio Licence Review

Worth taking a look at this to keep up with what’s going on

Why is the Autumn a good time to operate HF?

The Autumn has always been a Season where HF conditions improve and if you have recently
been licensed, with this being your first autumn operating on the HF bands, the chances are you
are in for a treat. But I hear you asking why?

The summer is not a good time for HF, apart from the relatively short-range intense Sporadic E
openings. However, the autumn brings improved conditions to the HF bands resulting in
openings to many parts of the world.

But why?

The sun passed through the equinox on September 22 and the long daylight hours it provides are
rapidly heading south as their Summer approaches. The result of this is that the ionosphere in
the Northern hemisphere is now cooling down and becoming more dense.

Another seasonal change occurs in the molecular-to-atomic ratio of the ionosphere. The affect of
this is that it is harder for the sun’s UV rays to ionise it.

Although it appears that the summer should be better for HF with all that sunshine, the reality is
that in summer the loss of ions (as they recombine more readily) overwhelms the increase
in production, and the total F2 layer ionisation is actually lower than it is in the spring and
the autumn.

The consequence is that although there is now less sunlight hitting the regions that make
up the ionosphere in the northern hemisphere the actual F layer ionisation is higher than
it was in the summer and D and E layer absorption is now lower too.
As a result we find that
the maximum usable frequencies (MUFs) during the day are higher than they were in summer.

The result of all the changes in activity means we are now seeing better openings on 20m and above,
including 17m (18 MHz), 15m (21 MHz), 12m (24 MHz) and 10m (28 MHz).

In October, openings should be possible to the eastern USA and the Caribbean in the afternoon on
10m, whereas in June these were unlikely to happen (apart from the odd multi-hop Sporadic E contact).

It would be worth , listening to 29.620 MHz FM in the early afternoon in October and you
are almost certain to hear the KQ2H repeater in up-state New York.

Because both hemispheres of the Earth are evenly illuminated this is also a good time for contacts to
be made on North-South paths –
we may also experience some good openings to South Africa
and South America
as a result.

On the flip side, the sun sets a lot earlier than it did in summer so we can expect the higher HF bands,
28 MHz (10m), 21 MHz (15m) and 18MHz (17m), to close earlier than they did, with only 14 MHz
remaining open until around 2100-2200hrs. This is hastened of course by the hour change in October.

If you get the chance, make sure you take a look at the HF bands as they will be significantly better than
you have been experiencing during the summer season. Remember, 10m might even offer you some great
DX, even with 10 Watts SSB and a simple dipole or vertical.

You will also notice that on the lower HF bands such as 80 and 160m DX activity will begin to increase
during the darkness hours. Take a listen around 3.798 early mornings to the lads running four square
antenna systems working the world to prove the point. You will probably hear David G0AIX with them
using his verticals.

Have fun.

Do you know your Locator Square?

When you first get on the air it can be very confusing. Sooner or later someone is going to ask you what your WAB square is, or your locator, or in a contest, what zone you are in.

Location information is used a lot in amateur radio. It can be used to work out the distance between two stations, or it can be used to collect awards. In some contests you get extra points for working specific “zones”, so it pays to know where you are!

Let’s take a look at what they all mean.

“Maidenhead” or QTH locator squares

The Maidenhead or QTH locator squares are mainly used on VHF, UHF and microwaves and plot where you are. For example, the square “IO” (Italy Oscar) covers the Western part of the UK, Scotland and Ireland.

The square is then broken down into smaller numbered squares that give more information as to your whereabouts—each of these squares represents 1° of latitude by 2° of longitude. Finally, two further letters define it even more.

For example, my locator is IO70JE.

If you want to work out what square you are in the easiest way is to go to http://f6fvy.free.fr/qthLocator/,
zoom in on the map and click where you live.

If you chase DX on 6m, 2m, 70cms or higher the chances are people will want to know this locator square.

The other way now of course is to use one of the various Apps available for the smart phones, even easier.

Worked All Britain square

The Worked All Britain Awards Group (W.A.B.) was devised by the late John Morris G3ABG in 1969.
The aim was to promote an interest in amateur radio in Britain and sponsor a series of awards based on the geography
of Great Britain and Northern Ireland.

You can find out more at www.worked-all-britain.co.uk

But in the meantime you might want to work out what WAB square you live in.
These are based on the Ordnance Survey maps of the UK and a simple way is to go to
www.streetmap.co.uk and enter your postcode. Once you have done that you’ll see a line at the bottom of the screen that says
“Click here to convert coordinates”. If you do you will see that the sixth line down is headed “LR”, standing for “Land Ranger”.
Now just take the two letters and first two numbers and these are your WAB square. So, as a test, enter the postcode—
NR18 0XJ—and you will see that the WAB square comes out as TG12.

Put your address in and see what your WAB square is.

Also available withing some smart phone Apps too of course.

ITU Zones and CQ Zones

If you enter HF contests you may hear people exchanging “Zone” numbers. This can be very confusing as it depends
what contest you are in as to what your zone is.

For example, the ITU (International Telecommunication Union) has the UK in ITU region 27. However,
CQ Magazine has its own zones, which are used in its contests such as CQ Worldwide Contest
(the SSB contest is being held on October 26-27 in 2013 by the way, an excellent contest to check out your station’s efficiency).

The CQ zone for Western Europe is actually 14.

Just to confuse you even more, we live in IARU (International Amateur Radio Union) region 1!

The best bet is make a note of all of your locator information so that you can refer to it when operating. If using 6m, 2m
or higher you will likely be asked for your Maidenhead or QTH locator. If anyone asks for your WAB square you will
also have it to hand. And you will probably only need the zone information if operating in a contest.

This sounds complicated but in reality it is not as you only need to look things up once for your QTH as the information
will never change.

If you listen to the GB3SI repeater identification CW you will hear it send the locator on the old system that pre dated
the current Maidenhead system and it sends from memory XK63J relating to its former home at St Ives School.
