Cockenzie & Port Seton
Amateur Radio Club is
affiliated to the Radio
Society of Great Britain
and holds the call signs
MM0CPS and GM2T which
are used for our special
event and contest entries.
The Club was formed by
Bob Glasgow GM4UYZ in
1984, to help the local
amateurs get to know each
other.
Far from being just a local
club we have members
regularly attending from
the Borders, Dumfries,
Strathclyde, Fife and
Newcastle.
The Club meets on the first
Friday of every month
(Second Friday of January)
in the lounge of the
Thorntree Inn on the old
Cockenzie High Street from
7pm till late.
I am writing this early due to a week’s holiday. Such is the pace of life lots to do and no time to do it in!!! Anyway I just cannot believe that we are now into the last quarter of the year and that the dark nights are well and truly here so it is once again time to sit back and reflect what you have done over the summer months. The jobs that you did and more than likely you will remember the ones that you didn’t. I myself had intended to do more operating from home but many factors have not allowed me to do so. On the Saturday after last club night my 7 September candidates sat and were initially given an indicative mark which to us showed they had passed their Foundation Exam. The process has now changed for the candidates for all the exams. They are given the normal paper and an Optical Marking Sheet (OMS). During the exam they can put their answers on the normal paper as before or fill out the OMS in pencil with their answers. Once they have finished the exam the last process is to use black ink on the OMS sheet to what they think is the correct answer, once this is done there is no going back as it is now deemed the final answer. For the Foundation and Intermediate as before the Invigilators mark the persons paper but cannot say if they have passed or failed but will give them the indicative
mark. The paper and the OMS sheet are then posted back to the RSGB where the OMS is scanned to produce a result. It is then that the candidate will be informed whether they have passed or failed. To those of us who been involved with the old system for years suddenly felt so deflated that we could not congratulate or commiserate the candidate on the day. Ok for progress but if the marked OMS sheet does indicate a definite PASS then I think we should be able to tell them. Basically as I write this I cannot offer the very warm welcome to them all to this fantastic hobby of ours. The Intermediate Course started on the 21st September with 5 candidates heading for their Intermediate Exam on the 19th October. I am sure you will join with me to wish them all the best with their studies and exam. There are still places left for the next Foundation Course starting the 2nd November and the Intermediate Course starting on the 23rd November. If you know of anyone interested then get them to contact me ASAP please. [email protected] September was very quiet with only one activity taking place and that was our second DF hunt night of the year, which I am sure again it will have thrown up a few topics of conversation.

The Club
The Club is run in a very
informal way, just a group
of like minded people
doing something they
enjoy!
This does not mean that
we don’t do anything, we
enter (and win!) contests,
train newcomers, hold
talks and video nights and
run a popular annual Junk
Sale. Our newsletter has
won the Practical Wireless
‘Spotlight’ competition on
several occasions.
The Club supports the
British Heart Foundation
in memory of a member
who died from heart dis-
ease by donating the
profits from some of the
events we hold, we have
raised over £15,832 since
1994.

To this coming month as always consult the Events Diary we have a talk by Geoff Crawley MM5AHO on his “2013 Lighthouse Weekend Adventures”. This will take place on Friday 18th October so I hope you will all make an effort to attend as I think this one will be very interesting indeed. On the contesting front there is a great demand for operators to take part in the HF Contest CQWW, which runs for 48 hours over the weekend of the 26/27th October. The CQWW contest is being run from Barns Ness so why not come along and either take part or support those who are operating, believe you me seeing a few people turn up and giving support really helps. If you can spare some time to operate please let Cambell know so he can arrange some sort of operating rota. To the future I can say that the Christmas Night Out as I write this hasn’t been organised but I am open to suggestions
which I would appreciate sooner rather than later. To be honest I have a lot on and do not really have time to go running around so hence any help would be appreciated. If someone else wishes to take over organising the event and then let me know. Lastly, this month I am once again looking for your input as I am now starting to look at putting next years monthly calendar together, so what you would you like to see done. I would appreciate a quick response, as I would like to get it completed quickly so that I can submit it to the radio magazines. I have at present nothing lined up. Thanks for your help. Enjoy the newsletter and see you all on video night and the HF Contest. Bob GM4UYZ
We originally planned a VIDEO/DVD Night for
October but once again Geoff MM5AHO has
kindly offered to give a talk on his Maritime
Mobile adventures for this year.
18th OCTOBER 2013 RESOURCES ROOM 1:
19:00 to 21:00
2013 Lighthouse Weekend and other Mari-
time Mobile Adventures
Talk by Geoff MM5AHO
After the success of Geoff’s 2010/2011 and
2012 Lighthouse Weekend event from his
yacht sailing around Oban and the Inner Heb-
ridean Islands he decided to do the same
again this year but this time from the Firth of
Clyde. The question is did he make it well why
not come along and find out?
He has produced another talk which he will
be delivering to the Club on the above date.
I hope you can all make the effort to attend
as I know it will be absolutely fascinating….

Special Events – The Whole Story
Talk by Bob GM4UYZ
This talk has been put together at the request
of some previous training candidates. As part
of our training program we often relate to
these events so I was asked well tell us all
about them and what is involved – so here is
the story.
Hope you enjoy it

This subject that we as radio amateurs should always be trying to improve, it could mean the difference of making that “elusive” DX contact or not. When we are operating from home, normally with a very restricted set-up, it comes even more prevalent as we normally have to work harder to make contacts compared to a full blown contest station with its mono-band aerials, linears and general set-up.
The key areas covered are as follows:
Your “ears” Radio Controls Antennas Logging software Keyboard skills Propagation Strategy
Your “Ears”:
Basically listen first and see what is happening because if you can’t hear the stations then you certainly cannot work them. Your ears are the best decoders going and are far better than any software decoders. They have the ability to pick out some-thing that no decoder will. Good advice as well is to use a good set of headphones i.e. HEIL headsets as this concentrates your listening plus they have the ability to cut out any local back-ground noise.
Radio Controls:
From the transmitter side the main controls are Mic Gain and Power Output. It is important that the Mic Gain is set properly and is good advice to set it as per the manufactures recom-mendation.
[Ed: the setting is personal preference but the advice I use is to increase the mic gain until the APC voltage just starts to rise]
Do not overdrive the radio by applying too much gain or by using too much power as this can cause distortion, unreada-ble signals and interference, basically we want our signal to be clear and clean so that we can be heard. If people do not hear you then they can’t work you.
On the receiver side there are various controls that can help you receive a signal better. There are Dual VFO’s to allow fast switching between frequencies for both Receive and Transmit. The RF Gain and DSP can be used to adjust the signal level to bring out that signal that you want. Then there is AGC and
here people have their own preferred setting but the consen-sus of opinion is set it Fast for CW and Slow for SSB. This con-trols the signal level through the IF of the radio with an aim to make it easy listening. Lastly there are filters. Depends on what mode you are receiving in to whether by default the IF filters will be wide or narrow. Normally Wide for SSB and nar-row for CW but by adjusting these no matter what the mode they can be used to bring out that elusive signal.
[Ed: many radios have RF attenuators which can be used to reduce the input signal under very strong signal conditions if you’re suffering badly from distortion but this should be used sparingly, if at all, add-ing attenuation or reducing RF gain is wasting all that gain you’ve paid for with big antennas and will prevent you from hearing that weak multiplier]
Lastly on the radio side there are headsets and a PTT footswitch. Certainly for contesting the recommendation is the HEIL headset with a HC5 insert as this produces a good contest signal but to be truthful they are ideal for home shack use as well. The advantage with headsets and using a footswitch for the PTT is that it allows hands free operating. It is also im-portant to mention that if a headset is used that the radio’s mike gain is checked and adjusted if required.
Antennas:
There is a wide range of antennas from wire, verticals, Multi-band Yagi’s and Monoband Yagi’s. What you choose will really depend on what your effective aim is. For example in the CQWW contest the best antennas are the Monoband Yagi’s whereas if the requirement is to work “local G’s” then the best would be low slung dipoles. The bottom line is to decide on your requirement and use the correct antenna. I know that for many the antenna is what we have at home and that is that as we don’t have the luxury of the contest level set-up. Then the answer is making the best with what you have. With regard to the club’s activities we certainly have the luxury of using any of the antennas in the list so when we are out and about we de-cide what we need and then set that up.
Logging Software:
There are many on the market all with their own advantages and disadvantages. As a club we have gone for Win-Test as it covers all the contests and activities that we are involved in. The major advantage is that only one program has to be learnt rather than numerous. It offers then slicker operating. Another major advantage it offers is the network of computers in a

Multi-Multi scenario and if a “computer crash-es” then there is no worry as it fully recovers the log, believe you me that is a fantastic step forward.
Keyboard Skills:
It is marvellous if you have already got good keyboard skills and can touch type as it speeds up the logging process. If you do not have this the golden rule is when logging, “single finger” mode is that you type as you speak i.e. logging GM4UYZ then type “G”, say “G”, then type “M” then say “M”, etc, etc in that way you control the logging. Speed and knowing the keyboard comes the more you actually type.
Propagation:
The Ionosphere layers which we use for DX contacts and when they are available during the day affects the transmitted frequencies to use, basically frequencies up to 10MHz are Night time bands and frequencies from 10MHz to 30MHz are day time bands with regard to HF propagation. Know what bands are open and when, so that maximum ad-vantage can be taken of them. The use of the “Grey Line” to make long distance contacts when one place is at dawn and another place in the world is at dusk is a technique that is used and is always studied by those wanting to work DX stations.
Strategy:
The strategy concentrates on dealing with a contest. Important points that need to be stressed is the reading of the rules, manpow-er, working as a team, role of a manager for decision making and crisis management and the ultimate aim of the contest.
Reading the rules needs to be done by every-one and not by a few so everyone knows what needs to be achieved, basically we are all singing from the same hymn sheet.
A suggestion of a “Band Manager” was made which we have implemented to a certain de-gree with his responsibility ensuring that the right bands are being used and when and what mode. At the end of the day the opera-tor is the principle decision maker. One thing from our own experience it is important that we all work as a team because without it the ultimate aim will never be achieved. The aim is to win the contest ultimately but I see it really is to always try and improve on where you reached before. It is also important that everyone enjoys themselves because without that you may as well have not taken part.
The above is just a guideline and an insight and you may see things differently or maybe can offer other advice but I think there and something in it for everyone from the casual operator through to the experienced operator

Transmitted interference (what we do to
others) is often dealt with in articles, and that
can indeed be a problem, but this piece
addresses received interference.
Trying to catch the details of that rare DX in
amongst the crashes and clicks from some
nearby unintended transmission can be very
frustrating.
Here’s a few ideas you can try to track down
that offending RF. How to identify it, locate it,
and eventually – stop it!
RF sources.
Many items can radiate RF these days, many
more than a few decades ago, when central
heating thermostats and power lines were the
prime causes. These days, many electronic
devices emit RF at some level, and in some
causes can be of a level to blot out the signals
(Continued on page 5)

we wish to hear. Often we are trying to resolve quite weak
signals, and it doesn’t take a lot of RF to drown the DX.
Locating a source of RF
Locating a rogue RF source is detective work. Think like a
detective. Ask lots of questions first:
When did this start? (and what else happened at the time- a
new installation somewhere?)
What frequencies are affected? (generally lower frequencies
travel further by ground wave)
What time does it occur? (Its hours of transmission might
give clues to identity, for example central heating during the
evening?)
What does it sound like? (more on this later)
Do any conditions such as weather seem to affect it? (if its
only in the rain for example, its likely outdoors)
One of the first steps to locating a source is to determine the
type of transmission. Listen to it on your receiver. Try AM,
FM, USB. Is it on more than frequency? If so at what spacing?
What does it sound like?
Here’s a few thoughts…
Clicking, pulsing, ticking type.
Automotive? – any petrol engines nearby? Does the
frequency of the ticking vary (as engine revs do)? Fast or
slow? Very slow can be electric fences.
Buzzing – unmodulated. A constant buzzing sound is often
power related. Might be a switch mode power supply (and
many devices have these today), or a power line fault.
If modulated it could be a TV or a monitor radiating a signal.
The modulation changes with image.
Voices: If your problem is music or voices, it’s likely a
transmitter causing this by either faulty transmitter, or some
intermodulation product mixing with something else. Go back
to the questions on frequency it appears at. Any logic to this?
Can you hear what’s said (voices) and identify it? If say Virgin
1215 kHz was mixing with Talk Radio, you might be hearing a
mix of these two at various frequencies from 1600kZ to 4
MHz. (I used to hear this from Westerglen TX site. It was a
faulty insulator on their mast)
Measure the highest frequency you can hear this RF on.
The higher the frequency, the closer the source is likely to be,
and the stronger the signal, the closer to your receiver /
antenna.
If you have a portable shortwave receiver, then is a handy
tool for tracing the source. Using the principle above (higher
the freq, the closer it is), you can move about and get an idea
of location. If you’re loosing the higher frequencies it appears
on, you’re moving away, and vice versa.
Fox hunts.
If you participate in fox hunts you might have a portable
directional antenna. It might be for VHF, and if your
Interference is audible at VHF, then you have the perfect
device for hunting down your source of RF.
Set the directional antenna up and rotate until the noise is
loudest. Note the direction of the antenna. Use a compass to
get a direction. Say it’s at 90 degrees (east of you).
Now move say south a ways, until the angle of loudest signal
is about NE, and take another bearing. If you mark these lines
on a map, you will find they intersect at the probable source
of your problem. To be sure, move to the north and see if
another bearing intersects at the same place.
This isn’t foolproof though. If a powerline is radiating this
signal, it will radiate over a length of line, and not seem as a
“point source”. Check the strength at your bearings.
Eliminating the Interference.
Finding the source of the interfering signal is only half the
battle. Eliminating it can be even more difficult, but is more
people related and so logic doesn’t always figure!
Someone is responsible for the device that’s radiating the
unwanted signal, but they might not share your desire to sort
out the problem. You might need to be a bit cunning in this.
Think about what is in their interest. If the device is
producing RF then it might be approaching failure. (eg points
arcing). So by you advising that this thermostat is about to
fail, and so cut off their heating, they’d be inclined to get it
fixed. But to just point out that its upsetting your hobby
doesn’t provide much motivation. I remember advising a

Thanks to the sterling
work by M0RNR, our club
has been added to the
excellent Clublog system
developed by Michael
Wells G7VJR.
www.clublog.org
The system allows
members to upload their
logs in ADIF format and
have them displayed in a
table with all the other
club members.
Clublog also has great
facilities for tracking your
DXCC status etc so is well
worth taking the time to
register and get your log
uploaded.
To update your log with
the next set of contacts
(SSB, CW or Data) you can
simply upload your whole
log again and the system
will take care of the
duplicates. Alternatively
you can export the bits
you want from your own
log and just upload that.
The tables we’ll publish
here will be the club,
filtered by the current
year, so everyone starts a
new year at 0 contacts.
Due to several amateurs
across the world
accidentally adding
themselves to the CPSARC
tables, we now approve
all additions which might
take a day or two.

power authority about a faulty insulator on a
medium voltage power line. While they were
intrigued about how I knew, they had a team
out to replace the insulator within days, and
solve both our problems.
Other issues might take a lot of perseverance.
The Broadcast transmitter mentioned above
took two years to get sorted.
An unorthodox approach is to suggest that
the person responsible does not have a
license to transmit as they are doing. You are
doing them a favour by pointing it out before
they get caught by the authorities. (I did have
a dismal failure with this approach once
though!)
In all your efforts though, be polite, be civil.
Demanding someone fix a problem they
didn’t know they had, that doesn’t affect
them, and about which they don’t care, won’t
get you far. Think about their motivation and
try to use that. Sometimes just appealing to
their good nature works.
Suffering in silence doesn’t help either. I’ve
heard of those that hardly touch their radio
because of local noise. But made no effort to
trace it and eliminate it. If you don’t it might
be that no-one does, and you suffer still. So
get hunting!

CQWW SSB CONTEST 26th & 27th OCTOBER – ARE YOU AVAILABLE? The club has taken part in this contest for a good number of years, in fact since 1997 and from our current site Barns Ness Lighthouse, Dunbar location since 1999. It is fantastic site for radio as the “noise floor” is an absolute minimum. In the 16 years of doing the contest we have entered two sections, ei-ther the MULTI-MULTI or the MULT-2 with 9 times in the Multi-2 and 7 times in the Multi-Multi. No matter what section you enter it is a long arduous contest as it runs for a full 48 hours. What makes it even harder is that we need to arrive at the site by no later than 08:00 on the Friday so that we can make use of what daylight hours that is available to get all the aerials and equipment set-up. This means that we are all up early and already tired before the contest actually starts at 01:00 on the Saturday morning. For those wondering what the Multi-2 and Multi-Multi sec-tions are then below is an extract from the 2013 CQWW rules: Multi-Operator Categories (all-band operation only): Any num-ber of operators is allowed. QSO alerting assistance is allowed. Only one transmitted signal per band is permitted at any time. Total output power must not exceed 1500 watts on any band at any time. Two Transmitters (MULTI-TWO): A maximum of two trans-mitted signals on two different bands may be used at any time. The log must indicate which transmitter made each QSO. Each transmitter may make a maximum of 8 band changes in any clock hour (00 through 59 minutes). Multi-Transmitter (MULTI-UNLIMITED): The six contest bands may be activated simultaneously. Only one transmitted signal per band is permitted at any time. When running as a Multi-Multi we have 4 stations set up all running at the same time...hopefully, but to continue this over the 48 hours takes a lot of manpower to sustain. What we are finding is that we do not have enough people to keep this go-ing flat out so the decision has already been made this year that we will enter the Multi-2 Section. This only requires two operators at any one time as only two stations can be trans-mitting. This will allow a better use of the manpower that is normally available. This is where the plea comes in. Can you help out and do some operating? If you can give us 2 or 3 hours of your time and take a stint of operating then it would allow those who are staying for the whole 48 hours a chance to catch up with some “beauty sleep” or just even rest. Also if you could give us even an idea off when you would be able to come then we can build you into part of the rota we normally put together.
If you are worried about the logging we can try and get a night set-up and give some tuition so that on the day you are not overawed. Is it the pile-up that you are worried about? Well there are ways to deal with that as well which maintains that you are fully in control, you just need to learn the technique which is quite simple. Is it the keyboard skills, well we have all been there and the more you use the keyboard the more fa-miliar it becomes but again as part of the pile-up technique there is a way to deal with it.

Less than 24 hours -- What Time? FOOD – Someone normally does a COSTCO run and buys food for the weekend? It is important we know as we have had food bought for people who said they were attending and then didn’t so it was wasted and plus it still had to be paid for by those who did turn up... Not sure if the COSTCO run will happen this year but if it is then DO YOU WANT TO BE INCLUDED? If you say YES and don’t turn up you will be included in the cost reimbursement You never know the contest bug may catch you and you will want to do this all the time.... fingers crossed says I!!!!!

On a club website forum I noticed a request for others to join a recent idea posted by Bernie GM4WZG. It follows some de-velopment of software by USA Amateurs, to convert WiFi rout-ers (a 13cm band transceiver in effect) into useable communi-cations devices for the amateur service.
It’s a coincidence that the WiFi band overlaps with the 13cm Amateur band, but a handy one.
Broadband Hamnet as its called is about as easy as setting up a WiFi router initially, with a downloadable firmware upgrade from the Hamnet website that re-configures the router for this new duty. So far only a few types of router are suitable, but fortunately these are older versions, and so readily available from Ebay and elsewhere for £10-20.
To quote the Hamnet website…
“Broadband-Hamnet™ (formerly called HSMM-Mesh™) is a high speed, self discovering, self configuring, fault tolerant, wireless computer network that can run for days from a fully charged car battery, or indefinitely with the addition of a mod-est solar array or other supplemental power source. The focus is on emergency communications.”
“In its current form it is built using the Linksys WRT54G/GL/GS wireless routers and operates on channels 1-6 of the 2.4GHz ISM band, which overlaps with the upper portion of the 13cm amateur radio band.”
After reading of how Bernie and Stan (GM8ZQY) had convert-ed routers and subsequently enabled them to move data be-tween their stations, I decided that I’d give this a go.
Stan and Bernie have used the connection mobile too, and had remote control of a camera, vision, and file transfer.
I found a cheap router on Ebay, in fact 2, so got them both cheap. I then bought a cheap 15 element yagi, same source, and a linear amplifier putting out 2Watts (with RX preamp).
Removing the router from its plastic box, I mounted it, the amp and the PSUs in an ABS enclosure and stuck the whole lot up a scaffold pole about 6m agl.
Interestingly, this firmware will “see” the WiFi routers of neighbours, but cannot connect to it. Similarly they would see my setup, but not be able to connect. I live in a fairly rural ar-ea, but can see about 20 WiFi setups, some several miles dis-tant.
I’m hoping to connect to Stan and Bernie some day, but the 32km distance might be a stretch, as the Torphichen hills lie between us.
In the USA, distances of 150km with a useful connection have been achieved.
So far there are no nodes listed on the website map of world-wide nodes, though I’m sure that we’re not the only ones play-ing with this technology. I’m hopeful that others will be en-couraged to join in this unusual aspect of our hobby, with a DX challenge that is of a different magnitude to HF, but in many ways as interesting.
These systems exchange data, but data is data and has many forms. VOIP, IP video, keyboard chat, music? Who knows. If you can turn it into data, it could be moved between stations and used. How about remote control of your remote HF super station? A local DX spotting system? Sound like packet radio over again? Maybe it is, but in a much faster, more flexible way than packet ever was!
