Dear Members & Friends,
Hello and welcome to the November 2011
Newsletter, which is edited by John G8IYS.
This last month has been fairly eventful at the
home QTH. Time has been spent “assisting” with
the purchase and transportation here of a
pram/pushchair/carrycot/car-seat in preparation
for the arrival of the junior – junior - op in the first
week of December and his consequential homing
here together with my son Gareth and his wife
Anna. The conservatory continues to fill with
baby-paraphernalia - growing greater in volume
and variety as each day passes – but not into the
shack - yet.
In passing, I discovered how open are the upper
HF bands: 17, 21, 24 and 28 MHz - even though
I have only a 6m length of wire, from an upper
window down to ground level, as an antenna. In
particular, I was surprised at how occupied and
strong were the SSB signals between 28.1 and
28.6 MHz – CW, CB strayers and legit amateurs
together with FMers between 29.5 and 29.7 MHz.
It was fascinating listening to FM Repeaters there
competing with eachother under the capture
effect. 24 MHz, on many mid-mornings UTC
delivered several VKs and multitudes of JA.
Also, before the ban is reinstated on solder
splashes on the dining room carpet, coincident
with the arrival of the enlarged family, I have
been refurbishing my 70cm transverter,
constructing a new 2m transverter and dealing
with the interfacing requirements of a new prime
On another tack, my trusty Rover 75 has finally
passed beyond economic repair at age 12 years.
This gave me an opportunity to continue my role
as a collector and acquire another one – almost
the last of the Longbridge production line, with
very low mileage, and it is an Estate - so I can

get the pram in and out without recourse to
supporting structures for my nether parts.
I can also advise the VHFNFD team that I have
had a tow hitch fitted. Thus, accommodation of
the 70cm station continues to be assured in my
trailer tent. Anyway, on with the news.
THIS MONTH'S MEETINGS by Hon Sec John
G3MCX
The first meeting, to be held on Monday 7
November , will be an illustrated talk by
Cedric Verdon. In his own words:
LONDON AIRPORT (LULLINGSTONE) – THE
AIRPORT THAT NEVER WAS.
During the 1930s the small size of Croydon Airport
and it's location in the London Fog Belt were making it
unsuitable for larger modern airliners. Sir Alan
Cobham was commissioned to locate a suitable site
for its successor and around 1935 the decision was
made to relocate London's main airport to Lullingstone
Park in Kent. Although land was bought and a railway
station was built, the plan was put on hold at the
outbreak of WW2 and replaced at the end of hostilities
by an unwanted RAF airfield at Heath Row. This
illustrated talk will fill in much of the forgotten detail.
Ced may make a brief reference, time permitting, to
his researches in connection with the forthcoming
Heritage Centre at Biggin Hill (see www.bhtrust.org.uk
and www.bhbobsc ). The Lullingstone Airport is only
one of the discoveries, most of which have resulted in
articles in 'The Bump' magazine.
The second meeting, to be held on Monday 21
November will be the regular Fix-it, Move-itOn and advice Clinic, led by John G8MNY.
Notes from the Hon. Sec., John, G3MCX
Please support your Newsletter Editor, John, G8IYS.
you do not have to be a member of the committee to
write an article for publication in the Newsletter. Too
much copy will make his life easier than too little. It
would help if it was an attachment in “word” and does
not have to be about radio. In July this year we had an
excellent article from Rick, M0LEP on his QRP
operation in Kenya and in the past we have had
reports and interesting 'info' from Ted, G3EUE,
John,G3BFP and Charlie, M0BIN. Ted has also sent
accounts of his trips 'down under'. Pictures are always
welcome.
I will start it off with two small items,one radio, one
not, which if are not included in the Newsletter have
been deleted by the Editor as a waste of space! Some
of you will know that I do not like a microphone and
have done most of my operating in UK CW contests
with the odd dabble in an international one to work a
few new countries. I have also done very little
construction but did, in the early 60's, make a copy of
a NFD Tx (807 PA) with a lot of help from former
member Rex Morrison, G3KGA. The VFO and buffer
worked well on all six bands, the PA stage had a coil
Issue 1 – for distribution
with a link wound on a toilet roll holder to connect to
the antenna which was good on 160 and 80. It had
cathode keying via a very noisy PO relay. One
afternoon, disaster: I wound and tested a PA coil for
20m on my own and completely blanked out the
screen on the old black and white TV that my Dad and
brother were watching just as the only goal in the Cup
Final was scored. (For the benefit of young folk
reading this: 3 x 14 MHz = 42 MHz = Band 1 VHF TV
- 405 lines. Ed) Since then the only work I have done
has been on ATUs and Antennas, mostly climbing!
That Tx never was completed but gave me a lot of fun
county chasing on Top Band for the Worked All British
Counties Award (WABC). I had 75 of the 97 possible
before Sandra and I got married in 1966, then
followed 18 months in a flat in Chelsfield, no real
aerial and very few QSOs at all until 1968 when we
moved to Orpington and had to start from 1 again. I
reached 43 before we came back to the old QTH in
South Croydon. By then all the Counties had changed
anyway and that was that. I will get on the Club Net
soon even if only to give a few signal reports.
Earlier this month on Wednesday 5th October I saw
this huge insect taking nectar from a Plumbago plant
in the garden, in all my years I had never seen
anything like it before, so described it to Sandra when
she came back from taking the dog in the woods. She
had seen one in Portugal when visiting our younger
daughter and family while they were camping. I
phoned Lucy and got an instant answer, Hummingbird
Hawk Moth, confirmed it on the internet and found out
that although it was not uncommon in the UK they did
like reports of sightings. I clicked on to do this and
discovered that 7367 sightings had been reported this
year up to 5th.October.
Last month's Meetings by Pat G4FDN
October First Meeting: This was the second of our
twice annual Surplus Equipment Sale. It was better
attended than has been our recent experience, with
several visitors from other other clubs, including
Bromley, Coulsdon and Wimbledon. There were lots
of useful items to be had – I got my 450 ohm ladder
line there that I used on my 4m/2m skeleton sleeve
antenna described later. I also picked up a Microwave
Modules 2m converter for £1. What we could do with
for future sales is more members bringing along items
for sale. Thanks to all those who made donations to
the club. The overall cash benefit to the club from
donations and commissions totalled £42. That
provides a very significant income to Club funds and
the means to maintain our very low levels of annual
subscription. Thanks to John G8IYS and Peter
G3ZPB for keeping the accounts, and to Gareth
G4XAT and Maurice G4DDY for the auctioneering.
October Second Meeting: this was an informal fix–it
evening. As usual, John G8MNY was on hand, well
equipped with tools, test equipment and advice. In the
picture below, L-R are Andrew G4ADM (from
W&DRS), Rick M0LEP, Charles M0BIN, John
G8MNY, Peter M1PFS, and Kim G6JXA.

So armed with this data I went and built one and
tested it. The picture of the ‘test’ model I made is
shown below:

The Chairman's Blog November by Pat
G4FDN
We start with a 4m/2m Dual Band
Skeleton Sleeve Dipole: For those of
you who read my blog last month, you
will remember I covered the Skeleton
Sleeve Dipole for the HF bands
following recent articles by Joel Hallas
W1ZR in QST. I was interested in this technique of
using slotted 450Ω ladder line for the VHF bands, and
in particular for 4 metres and 2 metres. As the articles
by W1ZR didn’t cover these bands I started
spreadsheeting and analysing the data in the articles
to see if I could extrapolate dimensions for 4m/2m. In
doing this I noticed the data for the 15m/10m didn’t
seem quite right, i.e. the lengths seemed short by a
factor of two. So with this discovery I e-mailed Joel
asking him to confirm my suspicions, which he did,
and also I mentioned that I was trying to extrapolate
his data to 4m/2m. In response he kindly calculated
the required dimensions using EZNEC which came
out as follows:
The centre of the dipole is a PVC electrical conduit
box that I bought at the last surplus equipment sale
and it seemed ideal for giving some mechanical
strength to the join between the coax and the 450
ohm line, and is shown in close up below. The ladder
line is held by cable ties to PVC conduit.
For testing, I put the antenna up to a height of 18 feet
on a wooden pole. In order to determine the
characteristic impedance, and hence SWR at the
feedpoint, rather than at the end of the coax, I used
feeder lengths that were multiples of half wave
lengths: one 4.035m and the other 4.995m. The coax
had a velocity factor of 0.78 (measured) so the first
length represented 5 x half waves at 145MHz and the
second 3 x half waves at 70.225MHz. I didn’t notice
any proximity effects moving the coax around when
testing, even with the shorter length of coax (MFJ269
just about 5 feet AGL and 13 feet below antenna).
Where A = 65 in, B = 35.5 in, C = 2.25in
Issue 1 – for distribution
Here is the data I measured with a hand-held batteryoperated MFJ-269 analyser:

ARLX007 WD2XSH Experimental Stations to
Be Active on November 3
A number of the WD2XSH experimental
stations will be on the air on Thursday,
November 3 to mark the 105th anniversary
of the Berlin International
Radiotelegraphic Convention. According
to ARRL WD2XSH Coordinator, stations
operating in the band from 495-510 kHz
will call CQ on 500 kHz and then QSY
to complete the QSO. Stations operating
in the band from 461-478 kHz will
call CQ on 474.5 kHz and then QSY. Other
stations may operate beacons with
special messages in the bands from 508510 kHz and 476-478 kHz. For a
complete list of stations participating
in the WD2XSH experiment, as well as
information on how to send your reports,
please see the WD2XSH website at
http://www.500kc.com/.

The main conclusion I have from this is that the ‘B’
length is a wee bit short for 145MHz, but next
weekend I’ll solder on a short length to the ‘B’ ends
and retest. Also the transformative effect of the coax
length needs to be taken into account for best
Issue 1 – for distribution
compromise match on both bands. I also suspect that
as no common mode choke was used at the feed
point that out of balance currents may be affecting the
MFJ-269 measurements, so I intend repeating the
tests with a choke in place, probably a few turns of the
coax rather than a ferrite bead sleeve.
I estimate that I cut the ‘A’ length to an accuracy of
1/16 inch and the ‘B’ length to better than that. So
overall, the EZNEC calculations seem quite good at
these frequencies.
Kindle: I don’t know how many of you are familiar
with Amazon’s Kindle –a very portable device for
reading and storing e-books, magazines, etc. Well, I
bought one just before writing this blog and I’m very
pleased with it. I have quite a few technical books in
PDF format –things like ARRL & RSGB handbooks
and magazines like QST, QEX, etc, and while I have
them on my laptop, using a laptop is not always
convenient, and weighs quite a lot more than the
Kindle which is a very light 170g. The Kindle is about
the size of a paper back novel and has a 6” diagonal
screen –which uses so-called e-ink which is really
Page 4 of 9
readable in bright sunlight unlike my laptop or
smartphone. The Kindle also has WiFi built in (as well
as USB) so you can connect to on-line sources such
as Amazon’s own store for buying and downloading ebooks.
Below are two pictures I took of the Kindle screen
showing a page from the RSGB Radio & Electronics
Cook Book, which given you some idea of the clarity.
Font size to small? –increase it with a couple of clicks!
–you can’t do that with a real book. You can literally
store hundreds of books on it –Amazon say 1400 for
the model I bought, but it of course depends on the
size of the book. The battery life is very good also: 4
weeks with WiFi turned off and 3 weeks with it on.
I will bring it along to our next informal meeting if
anyone would like a closer look.
NiCad/NiMH fast battery Charger: with my son
Michael off to university last month, my existing fast
charger, which covered AAA/AA sizes, went with him.
I had been on the lookout for something a bit more
capable and flexible and found it in Lidl for £12.99,
shown in the picture below.
This, I thought was an excellent price compared to
other chargers I have seen. As can be seen from the
picture, it can charge AAA/AA/C/D/PP3 cells/batteries.
What I particularly like about it is that you can charge
single cells, or multiple cells or batteries of different
sizes, and there is an LCD display to show the state of
charge on individual cells (the PP3 connections have
LED indicators). Testing two nearly exhausted AAA
NiMH cells, rated at 900mAH, they charged in 15
minutes!
A blow-up with a couple of clicks:
More newsletter contributions needed!: I make this
plea regularly, so if you have bought, built, or modified
something recently please share your thoughts with
the rest of us! Similarly, what and who have you
worked on the air recently? Been anywhere
interesting –please share!
Kempton Radio Fair Sunday 6th November: SRCC
will be represented as usual. If you have any
equipment that you would like sold on your behalf
please contact Maurice G4DDY. If you are attending
in person please drop by the club stand and say hi.
Also, if you are travelling by car, please consider if
you can take a fellow member with you.
That is all from me this month. Hopefully, many of you
as possible will attend our talk on the 7th November.

Plea from Steve G4FYF
Herewith extracts from G3BFP's recent logs. (Note
they are all CW – I did hear some of these, over the
Riddlesdown lump, but much too fast for me. Ed)
Wanted by Steve, G4FYF:
Is there a defunct Yaesu FT221 144MHz transceiver
out there? I am after the local oscillator unit, or, more
specifically, the 14.0333MHz crystal for the 145.0 145.5 MHz band segment. I am now fed up with
attacking my crystal with a soldering iron to get it to
work for the Friday night club net!…

From Peter G3ZPB re GB400KJB
It was 400 years since Bishop Lancelot Andrewes
authored what became known as the King James
Bible or the Authorised version. He lived and worked
locally although then the Diocese was a part of
Winchester! The operation of the very special
GB400KJB in late September has been a great
success in the grounds of Southwark Cathedral.
Radio contacts have been made with stations
throughout Europe, Norway, Germany, France and
Eire to name but five. The Market days of Friday and
Saturday were something to be believed, with wall to
wall people everywhere and lots of questions asked
as to what it was all about, no doubt as tents in the
Cathedral Grounds are not a normal occurrence!
Every day has soon something new - we invited
people to take part and our youngest "helper" was 3,
who had a talk with a German operator, and another
youthful operator of 5 chatted to somebody in Oslo.
Over the 11 day operating period we made in excess
of 500 contacts, mostly on 40M despite the sun doing
its best to blot us out at times, and been able to tell
people, many from abroad and across the operating
table about the exhibition and the 400 year old bibles
on display, within. Some expressed levels of
amazement while the visitor from the Bible Society
was gratified to see members of the public taking such
an interest. At many times it seemed that we were
also providing a Tourist Information Desk - fortunately
our knowledge of the surrounding area proved
adequate!
The message is out! Southwark is on the map and we
are now counting up how many other English
Cathedral Cities have been contacted, regretfully
Canterbury eluded us. We also established that it is
possible to operate between a high railway viaduct
and a similarly high Cathedral!
Perhaps operating in the open in September is not
everybody's idea of a good time, but the weather was
actually very good, although somewhat draughty at
times! It was really great to also have the support of
Clubs from Croydon and the SE, in all we had eight
operators (not including the two little ones, of course!)
A number of SRCC members attempted a QSO, but
most were unsuccessful. I (G8IYS) heard the station
on 7 MHz, with my bit of wire, but it was only about
S2. I suspect that the screened hole in the ground of
the Southwark QTH may have had an influence.

A tale from G8IYS – to make you choke?
Links from Charles M0BIN
I mentioned earlier some tribulations while attempting
to set up a new 2m transverter (Elecraft XV144) with a
new driver (Kenwood TS590S). An IF of 28-30 MHz is
employed. Although not absolutely out of the question
on 2m, I was somewhat surprised to hear an SV
coming in at fair strength with my 10 ele yagi on, what
I believed to be,144.5 MHz. Sadly, turning the
transverter off only diminished the signal. It was not
eliminated. Upon disconnecting the transverter and
making a direct wire antenna connection to the
TS590S, the signal came in at 30dB over S9 (noise at
S0). It was a station on 28.5 MHz, of course, and was
running 5 kW to a ten element yagi. No surprises
then, so far. However, when the transverter was
reconnected, powered, and NO antenna at all was
connected, the 28.5 MHz signal was still there at
about S5. So I shortened the TX and RX IF cables
and disconnected the PTT lines. The result: no
change whatever. The case on the transverter has
rolled aluminium sides, with well bonded ali plates
elsewhere. So the only route for a signal into the
system had to be along the power lead connecting the
PSU to the transverter. But this was only a couple of
feet long. It so happened that Charles M0BIN had just
sent along an internet link to a couple of sites detailing
a variety of rf chokes and I was minded to continue
my experiments along those lines. As soon as I
picked up the PSU lead, the signal dropped
enormously. Then I tumbled: the table I had been
working on has a glass top, supported by a
rectangular steel tubular frame about 2m x 1m in plan
and sitting on about 0.8m legs of similar material. The
PSU lead ran parallel to one of the sides. The antenna
was the table and the signals were capacitively
coupled into the PSU lead. I then remembered
reading an article long ago which employed a ferrite
yoke from a VDU, upon which a few turns could be
applied in order to make an hf balun. I wondered if the
same material could be used to make a choke. No
only could it, but it did. Here is a pic of the choke I
constructed. I can even still use the dining room table,
but free of the slightest hint of 28MHz ingress - until I
am banished back to the shack by the new arrivals, of
course.

A non amateur Radio plea from G8IYS
I wonder if anyone has a set of instructions/ manual
for what is known as a “Highline” in-car Sat Nav, TV
and audio system. It was fitted as a top line system in
the last marques of Rover 75 “Facelift”, MG ZT 180
and I think BMWs around 2004-06. In my vehicle, it
looks like this:
The rectangular screen on the LHS is the TV/Sat
Nav/Radio and Trip Recorder display. I have
exhausted all the threads on the web. I know such a
manual exists. I just missed one on ebay a few days
ago. Haynes Rover 75/ MG ZT Manual up to year
2006 admits of such installations but gives no info,
other than a picture. An iterative method (commonly
known as poking and hoping) will eventually deliver
the goods, but I think there must be a better way!

I also wonder if anyone has experience with in-car
digital tv upgrades for this or similar in-car systems. I
have found “Love my Auto” on ebay but that may not

be the only source. A personal recommendation for a
radio mechanic, skilled in such matters would be most
appreciated.

As a final item: We are now able to reproduce the
front page of the service sheet in memory of Tony.
John Headland G3BFP has added the following
personal recollection:
“I used to look forward visiting Tony's QTH which
usually began with a nice cup of coffee and biccies
provided by Ali and we usually chatted about the
world in general and then the invitation to 'The
Shack' . It was a real treat to see all the various units
he had, mainly for his enjoyment of working DX via
satellites. We would sit (space permitting) there as we
watched the clock which would tell us it was time to
tune into the particular satellite he was interested in
and lo and behold, there it was on its journey round
the world. The other thrill was keying his TX with its
aerial pointed at the Moon and hearing his callsign
coming back through space after it's double journey to
our nearest space neighbour. Those earlier days with
Tony were most interesting and it started me off in
working DX via satellites. Tony had another interest
and that was Amateur Television - which was well
suited to his altitude of about 600ft ASL. I believe he
had quite a few long distance QSOs God bless Tony
and I hope conditions up there are better than down
here."
