A regularly updated map showing the QTH locator squares and countries
worked by G3NPF on 50MHz is available by selecting the squares
and countries worked map. This map shows the squares and
countries worked since moving to the present QTH in July 1999.
Until the summer of 1999, G3NPF lived at Broadbridge
Heath, which is a village located 2kms west of Horsham and M1AIM lived at
Wisborough Green, which is a village
located 15kms west of Horsham. Broadbridge Heath is currently
the home QTH of G0UXM, G4PEY and G7EYL and Wisborough Green is currently
the home QTH of G3MOZ, G3PUX and M0EPX.
We have now moved to a location between Thakeham and Washington, both of
which are small villages situated approximately 17km south of Horsham, close
to the small town of Storrington, but we are located within the parish of Washington. There
are many radio amateurs in this area and G0SFL, G3XJN, G4MUJ, G7DQF, G7JRV,
and G8IPF are all located within 2km of our new QTH. There
is a photo of our house in the Picture Gallery.
This area is part of Horsham District
and, until April 2003, was covered by the parishes of Storrington,
Sullington, Washington,
Thakeham
and Ashington. However,
the parish boundaries have been changed, such that the area including our house
and the other properties in the vicinity, is now part of the new Heath Common
Ward of Washington Parish. All these towns and villages are
located in the county of West Sussex.
Our house is located in QTH Locator Square IO90TW and Great Britain is located in CQ Magazine's European Region, Zone 14 and ITU Region 1, Zone 27. Select Locator and Zone Maps to view how these worldwide location systems compare. All three are currently in use by the Amateur Radio Service, with the last of the three also applying to all other Radio Broadcasting and Communication Services. Unfortunately there is no real compatibility between these systems.
*********************************
So you think you know the Q-Codes? Then take a look at the list compiled by Jim, G4RGA, which gives the meanings of the 254 codes, out of a possible 676, that have been officially assigned meanings. We have also included the 27 that have been assigned unofficial meanings by the ARRL, together with alternative meanings for 5 others defined by Robert Harris in his book "Enigma" and some groups used by the Russian Military and by the German Police. There are three other "four-letter Q-Codes" that are not recognised in official lists but are used by the Amateur Radio Service and these are also included. Some of the official codes have quite bizarre meanings, see QUQ, for example.
If you are interested in the codes used over commercial RTTY, facsimile and automatic high speed telegraphy links, have a look at the list of Z-Codes, compiled by Ralf, DL4TA. This list includes the meanings of both the original Cable and Wireless codes, and the modern NATO codes.
There is also a full Morse Code listing. The Amateur Radio Service is now the only officially recognised radio service still using the Morse code for communication on an every-day basis. Although telephony and digital data modes are used by most amateurs, it is good that the "art" of using the Morse code is also being kept alive by many of them. This listing includes the International Morse Code, the original American land-line telegraph Morse code, the old American Navy code, the codes for the Cyrillic (Russian) alphabet, the codes for accented letters used in European languages and in Esperanto, and various procedural signals. There is also a brief note on the types of Morse keys that exist.
We have also included a section dealing with the Baudot (Murray) Code used by teleprinters.
If you want to know the meanings of the many abbreviations and expressions used on the Amateur Radio bands, there is a comprehensive, although not exhaustive, list of abbreviations and jargon, together with their meanings. The list also includes details of phonetic alphabets, reporting systems, and emission designations. There is also a list of the international Amateur Radio callsign prefixes.
If you would like to know how long a particular UK radio amateur has been licensed, and what the various UK callsign formats signify, go to the Licence Issue Date list.

I am a Chartered Engineer and was employed by Thales
Defence Limited (formerly, in reverse order, Thomson-CSF, Racal, Thorn-EMI,
MEL-a division of Philips and EKCO Avionics)
in Crawley, until I took early retirement at the end of March 2001.
I obtained my amateur radio licence in 1959 following eight years as a Short Wave Listener. I have receive and transmit capabilities on all bands from 160 metres through to 23 cms, including the 60metre (5MHz) experimental band, using most analogue and digital modes except fast-scan television and some of the more esoteric types of communication. The main antenna for 160m through to 10m, including 60m, 30m, 17m and 12m, is a Carolina Windom, matched by a homebrew "Picatune" remote auto ATU designed by G3XJP and described in a series of Radcom articles beginning in September 2000. The standby HF antenna is an 18AVT-WB vertical, but this does not cover 160m, 60m or the WARC Bands. I also have horizontal beams for 6m, 2m, 70cms and 23cms, together with verticals for 2m and 70cms and a halo for 4m.
Until recently, my packet station was operational 24 hours a day, on a frequency of 144.900MHz, using a dedicated quarter-wave vertical antenna but e-mails and the Internet have all but killed off the use of packet, except for DX Clusters and Bulletin Boards. Consequently, I no longer run the packet equipment continuously, although it is still available when required. Having now replaced dial-up with broadband, I now connect to the local packet cluster via the Internet.
When I was working, my main activities were confined to local working on 2 metres and 80 metres with occasional DX chasing on other bands, especially 6 metres. However, now that I have retired, I am more active on the bands, using a variety of modes. I still enjoy operating in HF contests with the local Amateur Radio Club. I am currently "Station Master" of the Billingshurst and District Net (the BADNET), which meets at 10.00 hours local time, every Sunday morning and Christmas morning, on 3722kHz +/- the QRM. This net has been in existence for over 50 years, but I have been Station Master for only the last 34 years. Although now effectively the Horsham Club Net, any station is welcome to join in.
In the early days, when I lived in Southend -on-Sea and belonged to the Southend and District Radio Society, all my equipment was home-brew, but I must admit that my main rigs are now Japanese black boxes. However, I still use home-brew linear amplifiers on the HF bands (400W PEP), 6 metres (120W PEP), 4 metres (10W PEP), 2 metres (350W PEP), 70cms (250W PEP) and 23cms (10W PEP). There is no need for a linear amplifier on 60 metres as the legal limit is 200W on that band. I was a Committee member of SDRS for over 12 years and subsequently served on the HARC Committee for 18 years.
My other main interests are computing, building model coal fired locomotives and going to the pub. Anne and I have adopted the Rising Sun in the hamlet of Nutbourne as our "local". I belong to the Mid-Sussex Model Engineering Club, which meets in Haywards Heath. I am afraid they do not yet have a web presence, hence no link. I am currently building a 3 1/2 inch gauge Britannia Class locomotive. Regrettably, this project has not progressed very far over the last few years due to pressure of other commitments. However, I have recently completed the building of a small Stuart Turner single cylinder vertical steam engine, photos of which are to be found in the "pictures" section of this web-site. Both Anne and I share an interest in full size steam engines and often visit the Bluebell Railway and other preserved railways and steam oriented museums.
I met Anne in 1991 when she knew nothing about Amateur Radio. Fortunately, she found it interesting enough to study for her RAE and finally got her Class B licence in June 1996 with the callsign M1AIM. She was trying to learn Morse but changes to the regulations have made this unnecessary and she now holds a Full Licence. We are both members of the Horsham Amateur Radio Club and I am also a member of the Radio Society of Great Britain. Anne and I live near to the small town of Storrington in West Sussex.
I was born in December 1939, in London, and subsequently attended Normanhurst School in Chingford and then Southend-on-Sea High School for Boys, having moved to Southend in 1951 with my parents. I am a member of the Old Southendian Association. After leaving school in 1956, I began work as an apprentice electronics engineer with E.K.Cole Ltd. and attended Southend College of Technology, now the South East Essex College, where I obtained my qualifications. I left Ekco Radio and Television in 1966 to work at the Marconi Company in Chelmsford, but returned to Ekco Avionics in 1967 and had nearly thirty four years continuous service until I retired, although the company name has changed many times over the years due to numerous mergers and take-overs.
I had intended to retire in January or February 2000 but that was delayed due to one of the many company takeovers, which made it financially advantageous to stay on a little longer, although I did go "part-time" and only worked a four day week for the final year before eventually retiring in March 2001. I had hoped that this would bring more time to indulge my many interests but I still seemed to run out of time to do everything. Nothing has changed now that I have taken early retirement. I still do not have enough time to do everything and now wonder how I ever managed to find time to go to work! I recently heard a good definition of "retirement": you get up in the morning with nothing to do and go to bed at night having only done half of it.
Until I retired, I was employed as the Domestic
Supervisor at the Rikkyo School
in England, a Japanese boarding school located between Horsham and Guildford. I
became interested in amateur radio after meeting Tony, G3NPF, and obtained my
Class B licence in 1996. I was intending to master the Morse
Code and get a full licence, but changes in the licensing regulations have made
learning Morse unnecessary. My existing licence is now a Full
Licence with the same privileges as Tony's. I have lived in
several overseas countries and I wish I had "discovered" amateur radio during
that period as it would have been very interesting to have been able to use
some rather exotic call-signs.
I was born in 1938, in Manchester, but spent most of my childhood and adolescent years in Edinburgh. I attended James Gillespie's High School and Edinburgh College of Domestic Science, now Queen Margaret College.
I am a member of the Horsham Amateur Radio Club, and often assist in contests by acting as a log-keeper but have not yet done any actual contest operating. I am also a member of BYLARA and often join their 80m and 40m nets. In the past, my operating was mainly confined to 2 metres, usually on FM but occasionally on SSB. I have my own 2m multimode rig, which can be connected to either a vertical 5/8 wave ground-plane or a four element horizontally polarized beam. However, now that I have a Full Licence, I am able to use Tony's high power gear and the main antennas on any Amateur Radio band. My other interests are cross-stitch needlework, gardening, cooking and going to the Pub with Tony. We have adopted the Rising Sun in the hamlet of Nutbourne as our "local". There is a photo of one of my cross-stitch samplers in the "pictures" section of this web-site.
Tony and I live near to the small town of Storrington in West Sussex. Now that we have both retired, we thought we would have more time to enjoy mutual interests, although less money to spend on them. The latter is unfortunately true but the former has not proved to be the case as we still find that there are not enough hours in the day. How did we find time to go to work?

The picture of us both on the opening page of this web site was taken on the summit of Mount Snowdon during a recent holiday to North Wales. We felt it was a more appropriate image than the one taken sixteen years ago, as we have now both retired and look somewhat older, or should we say more mature. The old photo was taken in more formal circumstances at a party to celebrate Tony's completion of 25 years service with Thorn-EMI. The photos on the personal profile pages are still the originals of sixteen years ago.
Tony is often on the HF bands and Anne often joins the various BYLARA nets on 40m. Tony has the necessary NoV for experimental operation on 5MHz, but finds the activity very low.
Model and other engineering projects continue spasmodically.
In the garden, last year's crops have all been harvested and Anne has cleared the vegetable patch and has started this year's sowing.. Tony has planted 20 kilos of seed potatoes, which may seem a large quantity but the soil is very poor and shaded from the sun for most of the day so the yield per plant is quite low. The grass has already needed cutting three times this year.
There are currently about fifty fish in the garden pond. There has been a little breeding activity but very few small fish have been seen. The frogs have produced spawn but it has fallen prey to frost. We have seen newts and hope that their spawn will not suffer the same fate.
Visit the HARC Home Page for details of club meetings, local events, club members, etc. There are histories of HARC and the BADNET (the de facto Club Net) in the "Odds and Ends" section of this web-site.
HARC achieved 5th position out of a total of 74 participating clubs in the 2006 RSGB Club Championship Contest, with Worthing achieving 25th place. In last year's competition, HARC achieved 13th position out of a total of 66 participating clubs, with our local rivals Worthing sitting in 23rd position. Our other local rivals, Crawley, finished in 46th place.
The 2008 contest is now at the half-way stage and HARC is currently in 9th position out of 59 participating clubs. Worthing is in 30th position and Crawley is in 42nd position.
HARC won the 2005 Club Calls Contest, as we had hoped to do. In 2006, HARC again entered nine stations and achieved second place. HARC has won the RSGB's David Hill Memorial Trophy, twice but last year only managed 3rd place. The leading Club Station in the contest was the Worthing and District Amateur Radio Club GX3WOR who therefore won the Ariel Trophy, with the Hadley Wood Contest Group again winning the David Hill Memorial Trophy. The HARC entry is shown below:-
9 G3LET 1557 *
16 G3WZT 1447 *
18 G4LRP 1369 * * Stations
comprising the HARC Entry.
23 G3SWC 1259 *
25 G3NPF 1223 *
32 M0GJH 1193
46 G3ZBU 935
The Club Station G4HRS was not on the air last year. G4LRP and G3NPF submitted error free logs.
HARC achieved 29th place in the CW Section of the 2008 AFS contest, out of a total entry of 89 club teams. The HARC team comprised only two stations, G3LET and G3SWC, whereas a maximum of four are allowed. Their position is all the more creditable as all but three of the entries above them comprised four stations and they were the leading two station entry. G3LET achieved an individual placing of 18th and G3SWC came 78th, out of a total entry of 241 individual stations.
HARC "A" achieved 14th place and HARC "B" achieved 49th place in the SSB section of the 2008 AFS contest, out of a total entry of 89 club teams. The HARC "A" team comprised G4TPO, G3SWC, G3NPF and G3ZBU. The HARC "B" team comprised G3OGP, G4LRP and M0FRH. The individual placings were G4TPO 31st, G3SWC 62nd, G3NPF 64th, G3ZBU 111th, G3OGP 122nd, G4LRP 139th and M0FRH 176th out of a total entry of 254 individual stations.
HARC only managed 11th place in the unrestricted section of the 2006 HF SSB Field Day and did not enter a station in 2007. It is hoped to make a big effort this year.

As a bit of nostalgia, we have included a few very simple programs, written by
G3NPF back in the Commodore Plus-4/Amstrad 1640 days. These programs are freeware,
but G3NPF retains the copyright. You are free to use, copy and redistribute them,
provided no charge is made.
They were originally intended to run on MS-DOS machines using VGA displays, but
they should run OK on computers using either Windows 3.1 or Windows 95/98/2000.
All the programs are compiled from originals written in QuickBasic 4.5. G3NPF
does not profess to be a writer of good code, but if you are interested in the
BASIC versions, select the ".bas" filenames. These must be run in the QuickBasic
environment. Select the ".txt" option to obtain a zipped text version of the
basic code. It is not elegant programming, but it works!!!
easter.exe (easter.bas) (.txt) Calculates the date of Easter
daydate.exe (daydate.bas) (.txt) Gives the day for a given date
atten.exe (atten.bas) (.txt) Designs "T" or "PI" attenuators
locate.exe (locate.bas) (.txt) Converts NGR-to-Lat/Long-to-QTH Locator
Some time ago, I started teaching myself to use Visual Basic 3.0. My first
attempt at using it was to write a Windows version of easter.exe. I have not
done any more for some time and I think I have now forgotten all I had learned!!
You must have VBRUN300.DLL, or a later version, in your WINDOWS\SYSTEM directory
to run this program. It is probably already there, but if not, you can download
it from here.
easter-w.exe A Windows program to calculate the date of Easter
Perhaps, one day I will write a really useful program. If and when that happens,
it will be included on this site, but don't hold your breath!!
