Sleep well, George.
You inspired many a constructor. We must carry on your great work.
Sleep well, George.
You inspired many a constructor. We must carry on your great work.
Thankyou from Reading and District Amateur Radio Club for another great opening event to the rally season for our area.
It seemed like most of RADARC attended.
14th Feb Woodford Park meeting is a chance for us to catch up on the
various projects/activities we’re up to – in particular any follow ups
to the Great Construction Contest but not limited to that.
If you’d like a short (5 minute or so) slot let me know.
Doesn’t have to be stuff – could be contest updates or how RADARC
contributes comms to events like 3 towers etc.
Also – what would you like to see and I’ll try and arrange?
We can take contributions on the fly on the evening if need be.
If necessary, I’ll bore you for a few minutes before the bottles and
tomatoes start flying:
We’ll have the ICOM IC7300 out for people to have a play with and the spectrum analyser.
Tea, coffee and biscuits will be in plentiful supply all evening.
Looking forward to hearing from you.
It is with a tremendous amount of regret that I have to let you know that club member Stephen Coleman, G4YFB, passed away on Friday 4th January aged 66.
He had been battling cancer having been diagnosed only 9 weeks ago.
Steve was a supporter of the Club and recently had been helping Ray with the Intermediate and Foundation courses. Going back to the 80s, he taught the RAE course.
Also, he was a member of the Thames Valley Repeater Group (TVRG) and had used his software talents to provide modern programming software for old PMR radios we had for sale. Those of you that were into packet radio may remember that for a period most of the U.K. mailboxes used the YFB software.
A man of hidden talents who will be very much missed.
” It is very sad to learn of this news. Steve always had a lot of time for anyone. I know he dedicated a lot of time to writing the programming software for the VX-10 before TVRG set about selling them a couple of years ago. He will be missed. ” – Jonathan M0JSX / K6JSX
“Steve gave a talk to the Farnborough and District Radio Society In 2016 and always greeted me when he saw me at rallies. RIP Steve gone too early.” – Phil G1LKJ
“Sorry to hear the sad news about Steve, much to young.” – Min G0JMS
“I am very sad to have lost an old friend and enthusiastic supporter of everything. His dry sense of humour and ‘can do’ attitude was always an inspiration. He will be a great loss to the club and the wider Amateur community.” – Baz G8DOR
“I knew Steve initially through the talk on the Development of Radar and Virtual Radar he kindly did for the club in May 2017. From that it was clear he was a prodigious software talent developing his own ADS-B decoding software. He was very thorough in the prep he did for the talk bringing along examples of kit and demonstrating them. He made it look easy. Anyone that’s ever tried to demonstrate stuff will know, it’s really not.
He was completely self-taught in software. With the hard stuff he was tackling and the results he got, that’s quite remarkable. I was hoping to learn more of the magical things he was doing with TVRG particularly in the area of software for commercial PMR sets.
Someone with Steve’s talent, experience and kind unassuming nature getting involved with training was always going to be a perfect match. I will very much miss him” – John G4RD
The funeral be held at the English Martyrs Church, 67 Liebenrood Road, Reading, RG30 2EB, Berkshire at 13.30 on Tuesday January 29th. This will be followed by a burial at Caversham Cemetery, All Hallows Road, RG4 5LP at approximately 15.00. A “reception” will then follow at the Travellers Rest Public House, 180 Henley Road, Caversham, Reading, RG4 5DL, at around 15.45 onwards.
Dress code is informal – what you feel happy with.
If you wish to send flowers, then these can be ordered via the A.B. Walker website www.abwalker.co.uk Alternatively donations can be made to the Sue Ryder charity, again via the A.B. Walker website, although at the time of writing this hadn’t been set up.
Chris G4CCC and John G4RDC

Happy RADARC New Year to you!
Next meeting is Thursday 10th January, Woodford Park, Woodley.
Eyes down 8pm.
This time it’s the club equipment that’s the star of the show with the new Rigol spectrum analyser and the Icom IC7300 transceiver “Top of the Bill”. However Ray G3SCZ will also give a short introduction to the spectrum analyser and what it’s capable of. Many thanks to Ray for that.
It will be less formal than ‘normal’ talk evenings. This is more a chance for you to play with stuff – and have a natter, of course.
Also note the “humble support acts” are very capable (antenna analysers etc.). If you haven’t used one and you enjoy messing with antennas do come along.
This is a great opportunity to see how test equipment can make your life much easier and what radio equipment we have that’s ready to use.
Bring along any filters you may need aligned, also attenuators and dummy loads to find out what they’re really doing, and antennas within reason. Alignment evenings reborn!
On show will be:
+more, will keep you updated.
This will also be a good opportunity to discuss what our next equipment purchase should be. One obvious thing I’d say is missing is a decent, modern (i.e. small, light, capable) RF signal generator. Others:
Would be good to chat about what makes sense to purchase as a club and what not.
Tea, coffee, biscuits will be in plentiful supply – perhaps a bit
earlier than usual. But only for humans/our membership. A valve linear at full throttle drinking a cup of tea doesn’t bear thinking about! As ever, keep your meetings ideas coming. If you mentioned something to me before and I’ve not done anything about it, please nag me.
Season’s greetings all,
(Hopefully you can read this. I’m battling the new ‘wordpress’ interface as you may be able to tell.)
John G3VHH notes we have a new 4 metre web SDR available to us covering 69.492 – 71.028 MHz
IP address may change so look at http://websdr.org/ for a definitive address. Text is “4 Meter WebSDR Located in south Hartfordshire UK using a RTL Dongle”. Antenna is a 4 metre quarter wave ground plane.
Many thanks to John and Steven M0XVT for making this available.
With a very heavy heart, I must report that Peter G4JNU died peacefully on Sunday 23rd December.
Peter was held in the highest regard by everyone who knew him. Here are just a few of the tributes:
“As usual I had an amazing demo of a magnificent piece of early 30 line TV equipment he had been working on” – Vin, G4JTR
“Terribly sorry to hear about Peter” – Sean, 2E0ZIP
“Very sorry to hear the passing of Pete, we will miss him” – Michael M0MPM
“I also have very fond memories of Peter, G4JNU. He will be remembered for his re-creation of Baird’s mechanical scanning TV system and the transmission by amateur radio to the USA of these images from the Amberley Museum. He has always been a great experimenter and home constructor.” – Harry G3NGX
“What a shock. Such a nice man and regularly saw his car (registration G4JNU of course) parked here in the village, visiting family or out walking.” – Don G3XTT
“What a huge shame. Peter was a stalwart of the club for as long as I can remember. A true gentleman and a real engineer of a kind you so rarely meet. He will be greatly missed.” – Baz G8DOR
“I mourn the passing of a gentleman in every sense of the word. Peter had so much to teach us all. ” – Ray G3SCZ
“Truly a gentleman in every sense and an inspiration to me and many, many more.” – Dave M0PMZ
“I am truly devasted by this news. Pete was a rock at RADARC and had energy and helpfulness which few could match. RIP Peter, I shall miss you.” – Robin G4IWS
“Peter was a master engineer and always ready to lend a helping hand where needed. The equipment he built and demonstrated were an inspiration to us all. A loss to RADARC. RIP Peter.” – Jim G0LHZ
“He was normally an early starter at the rally helping out where ever he could always with a smile and then going on to the club table. At meeting he would busy himself with getting the room ready before chatting to all. I was astonished by his knowledge on mechanical TV and was able to help him with a presentation he was doing. He gave more than he took.” – Min G0JMS
“A very sad loss. I have many fond memories of Peter over the many years that I have known him. A great enthusiast for all thigs radio and mentor to newer members of RADARC. RIP Peter” – Andy M5ALG
“I never heard Peter complain or judge any one, he always came to the Club Meetings with warmth and a smile. Following on from Min’s comments may I add the tables for the sound and projector were always in place in ample time for the AV. set up . He braved the pull up/fall down finger crushing screen on many occasions! Peter was a regular for NFD set up and tear down and the McMichael junk sale tables , in mature years struggling valiantly with heavy boxes and boat anchors. In memory of a true gentleman. Sadly missed” – Graham G3XYX.
“I always remember the first time I entered a construction contest and thought I was in with a chance with my MSF clock… only to have Peter lift a large box off of his built-from-scratch replica of a Baird televisor which immediately dashed everybody else’s chances. His knowledge of original TV systems led to him making things for a BBC programme a few years ago if I recall correctly. Rest in Peace Peter. You will be sadly missed.” – Des, G8FIF
“A sad loss to the club and to amateur radio. Peter had a great depth of knowledge and experience, he was always willing to listen to the other persons point of view and was greatly respected by all.” – Dave G4BOO
I will close by noting Peter was awarded the Bingham Shield at the RADARC AGM for his tireless support for the club and in particular for sorting through and testing hundreds of valves which raised a considerable sum at the McMichael Rally. Most recently he gave a beautiful demonstration of his ‘Marconi Detector’ at Dr. Elizabeth Bruton’s talk in October.
He was thrilled to bits with the award – particularly as it had his name on it. Peter – it’s yours for that and so, so much more.
I consider it a privilege to have known Peter. Brilliant engineer, gentle soul.
The funeral service will be at St Andrews Church, Caversham Heights, on Friday 11th January at 2 pm followed by a wake at a local venue to be decided.
See https://www.standrewscaversham.org/ for details on St Andrews.
Graeme G4XOF lost his battle with cancer Monday 26th November 2018.
Here he is last June proudly showing me his mobile HF antenna, mobile mount and describing how it can be used very effectively as a base station antenna. Ever the enthusiast.
Sad news and he will be missed with his upbeat attitude on the radio to everybody He made the most out of the time he was given – Min G0JMS.
Still a shock even though I knew about Graeme’s condition. He was such a pleasant and helpful person – Mike G4CDF.
I heard him many times on the local repeaters during my journey to and from work, and his great personality and sense of humour always came bounding over the air waves, often making you laugh out loud. He will be missed. – Simon M0ZSU
Very sorry to hear about Graeme’s passing. A really nice chap to buy a radio from. Honest and very thoughtful. A pleasure to do business with. – Harry G3NGX
In a multi-way QSO, late comers with the same name as established operators, would add a 02 ident to keep things simple for the life of net. I was always touched and humbled by Graeme 2 referring to me with respect for an old timer as Graham 1 whatever the situation, eyeball or net. A font of shared knowledge at the informal Rugger Club gatherings. A help with e-bay bulk purchases saving time and trouble all round for the less adventurous net users . He was dynamic, pushing forward with technology , but always could take time out to explain something I did not grasp about new technology , a true gentleman . A great loss to amateur radio. – Graham, G3XYX.
I didn’t know Graeme well which makes this all the more difficult. I wanted to know him better. It feels like we’ve been friends forever which is a measure of Graeme’s warmth of spirit. We always had a laugh whenever we spoke either on air or in person. That said, Graeme knew his stuff. I affectionately knew him as XON/XOFF (https://en.wikipedia.org/wiki/Software_flow_control). He visited me at home last June where we just talked for 20 minutes or so about 5MHz mobile contacts we’d had, the up-and-coming network radio technology and how he used his mobile HF antenna to great effect mobile and at home. We had a drink or two at Reading Rugby Football Club in Sonning during the summer and the last time I saw him was at the Flight Refuelling rally at Wimborne, Dorset in early August with a number of the RADARC crew where the weather was dreadful but he was chipper as ever. Something to think about, that. A true radio man; one of a kind. I will miss him greatly.
The funeral is on Monday 10th December 3.15pm Reading Crematorium, South Chapel All Hallows Road, Reading, RG4 5LP.
Next meeting (22nd November) Simon Watts G3XXH joins us to give us a brief history of RAF ASV radars from 1940 to 2010. (ASV = airborne surface vessel, radar for maritime patrol aircraft)
Venue: Woodford Park Leisure Centre, Woodley, RG5 4LY
The history of airborne radars developed in the UK for long range
maritime surveillance by the RAF spans from 1940, when ASV Mk. I entered service on Sunderland and Hudson aircraft, through to the 1980s, when the Searchwater radar entered service on the Nimrod MR2. This history came to an end in 2010 when the Nimrod MRA4 programme was cancelled and the Nimrod MR2 taken out of service. The early radars operated at VHF. Following the development of the high power magnetron, operation moved to S-band and then to X band. Searchwater was a complete departure from earlier radars, incorporating a TWT transmitter, modern signal and data
processing and computer control.
This talk will give an overview of the design and evolution of these
radars, the aircraft they were used in and the performance they
achieved, detecting ships and submarines.
Simon Watts G3XXH is Visiting Professor in the department of Electronic and Electrical Engineering at University College London and formerly deputy Scientific Director and Technical Fellow in Thales UK.
Whilst googling ‘ASV’ I found this interesting link:
Min G0JMS also spotted “The Secret of Tuxedo Park” on PBS America talking about the development of radar by Wall Street tycoon Alfred Lee Loomis:
Thankyou to George M0GXB for making this meeting happen.
Refreshments afterwards as usual.
