Email: [email protected] Page 3 of 59 THE EDITORS DESK - Ron VK3AFW In this issue we have the obituaries of three well known club members, Harley Kerr, VK3CHK, Arthur Evans, VK3VQ and Rolphe Fox VK3JWL. This highlights the need for more new enthusiastic members. Also we have the VK100ANZAC operation which I’m pleased to say was a great success, mainly because it was supported by 12 members. Each one was presented with a certificate of appreciation. A full report is in this issue. There is also a report of a couple of SOTA activations and the usual material, including details of the VK Windom MK II. There is an article on this years successful Hamfest. Another Club, the Rotorua Amateur Radio Club in New Zealand is the latest to have picked up on APC News and reprinted one of our past articles in it’s current issue. We have the opportunity to use some of their material. As always, we can only print what material is forwarded to the Editor. So do your bit, please, to make the issues informative. 73, Ron, VK3AFW APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 4 of 59 THE PRESIDENT’S PIECE Greetings to you all It has been a busy time for the Club starting with Ron VK3AFW leading our team that to put the VK100ANZAC call sign to air as our part of the 100 year ANZAC commemoration. The following Weekend was our Hamfest at Southern Community Centre in Police Rd. To me it was one of our better hamfests in that everyone knew what they had to do and made it happen. Well done and thanks to all of you that contributed. We could not have done it without you. And on Sunday 17th May we had a JOTT event we supported. See short article in this edition. After many years of service to the Club the multiband Fritizal antenna has been replaced. We think it has been up for 25 Years and the Stainless steel wire was tired and rusted. Thanks to Tony VK3CAT for putting it up. Things coming up are the International Museum Weekend on Saturday 20 June at which time we have an Open day. Noel VK3BMU is publishing this event in the school and Local papers. The International Lighthouse and Lightship Weekend is on the 15-16 August Hope to you at the Club. 73 for now Ian VK3IFM APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 5 of 59 THE VK100ANZAC OPERATION The Club was able to secure the use of the VK100 ANZAC call for the week of 2nd to 8th May 2015. The venue was the Mentone Memorial Gardens adjacent to the Mentone RSL supplemented by operation from the home stations of Lee VK3GK, Graeme VK3GL and Ron VK3AFW. We were fortunate with the weather for the three days in the gardens, Saturday through to Monday. The Club Gazebo was set up with tables and chairs on a paved area in the gardens adjacent to the flag poles and Wreath Stele. The power was obtained from a council owned outlet a few metres away. An Off Centre Fed Dipole with a modified feeder arrangement provided operation on 40 m through to 10 m with the Club’s TS2000. A 7 m squid pole supported the centre of the dipole with one end being secured to the top of a light pole and the other to a fence. On the Saturday Ian VK3IFM (our honorable President) and Ian VK3XI along with Ron VK3AFW collected the necessary equipment from the Club rooms and proceeded to the memorial Gardens where they were met by Gerard VK3GER. Initially it took 45 minutes to set up but by the third day set-up time was down to just over 20 minutes. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 6 of 59 THE VK100ANZAC OPERATION CONT’D The station operated continuously from 10 AM to 4 PM on the three days. Because the Club members responded to the call it was easy to rotate operators and log keepers. Nearly 300 contacts were made covering all VK states, ZL and some US, JA and European stations in the log. ANZAC biscuits provided by Gerard and coffee kept the operators awake and on their toes. Left: A general view of the station looking south. The taller squid pole supports the HF antenna and the smaller one the 2 m antenna.

APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 14 of 59 THE VK100ANZAC OPERATION CONT’D Lee VK3GK, Graeme VK3GL and Ron VK3AFW used their home stations to push the total number of contacts close to 1,000. A significant portion were European stations. British, and French stations understood the reason for the commemoration. Above: The grand old 1880’s mansion that is the home of the Mentone RSL APC NEWS Number 239 May—June 2015 www.mdrc.org.au We did not make any contacts into Turkey, either because of conditions or lack of operators over there at the time. Page 15 of 59 THE VK100ANZAC OPERATION CONT’D The only operational problems we had were that the RSL was not open for lunch, contrary to expectations and we had some RF feedback and a hot microphone until Ian VKL3IFM added a counterpoise to the earth connection of the TS2000. Ron VK3AFW found an excellent pie shop in the nearby Parkdale shopping centre thereby solving the food problem. Above: The TS2000 with accessories.

When operating from home Ron VK3AFW reported that it was hard going at times with up to five or more dx stations calling at the same time, many with unfamiliar call signs requiring many requests for “say again”. The event co-ordinator Ron VK3AFW extends his thanks to the Kingston City council for providing the venue and mains power, The Mentone RSL for the use of their facilities and all the Club members who assisted both in the field and behind the scenes.. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 17 of 59 MT BEENAK & MT SPION KOPJE When Tony VK3CAT announced he had a leave pass for Saturday 7th March and would I like to join him on a SOTA activation I didn’t hesitate. He Suggested Mt Beenak and Mt Spion Kopje. I had activated Mt Beenak previously so I knew it was a straight forward walk in of about 1.5 km on a graded road. With about 140 m climb. The name Spion Kopje had always fascinated me so it was a desired destination. I set up my GPS and it suggested travelling via Yarra Junction and head towards Powell Town rather than via Gembrook which had been my previous route. The road was sealed all the way to the marked turnoff about 2 km past Gladysdale. The Mt Beenak Road is unsealed is suitable for 2wd but due to recent rain was a little slippery in parts and I was pleased to have AWD.. Our arrival and walk to the summit was uneventful. There was no view due to the top being in cloud. See picture right of Tony on the summit with the fire spotters tower in the mist behind him. The summit height is 745 m APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 18 of 59 MT BEENAK & MT SPION KOPJE CONT’D Tony and I set up a hundred metres or so apart on tracks that ran off the summit road. Tony went for SSB to work 4 S2S contacts then to CW for another 17 contacts all on 40 m. I settled on using my Chinese X108 wit 20 W of SSB. I had 3 contacts on 30 m and 2 on 40 m both of which were S2S. Time was ticking away so we packed up and headed for the car. Lunch and coffee seemed a good idea We drove out of our roadside car park adjacent to the sturdily locked gate on the peaks access road and the sharp left turn and kept left at the junction of the Gembrook road. At this stage Tony took over navigating from a map with me cross checking what the GPS was showing. As with the Mt Beenak road we traversed some attractive mountain forest. The road struck east with various names commencing with Bunyip road until we found the section named Limberlost Road . The access track to Mt Spion Kopje summit runs off this road and commences almost exactly opposite Outlook turnoff. We arrived in the opposite direction to most activators. The track was once a 4WD road to a fire spotter’s hut at the top but the further into the bush you walk the less obvious is the trail. It was marked in places with blue ribbons but mainly it was a matter of following Tony up the hill through the path of least resistance from the scrub. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 19 of 59 MT BEENAK & MT SPION KOPJE CONT’D The climb is about 350—400 m long and height gained about 90 m. We got to just below the summit and decided we need not bush bash the last few metres. I set up on the side of a large flattish exposed granite rock. Tony set up a little lower down. Here I went straight to 40 m and completed 16 QSO’s including 4 S2S. Tony again used CW for 6 contacts and 5 SSB contacts on 40 m. Tony managed to attract a number of leeches which were discarded after retracing our steps back to the car. Right: On Spion Kopje. The VK3AFW doublet with 300 ohm feed.

APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 20 of 59 MT BEENAK & MT SPION KOPJE CONT’D We retraced our steps to the vehicle and then drove further east through the Yarra State Forest intersecting the bitumen about 3.6 km west of Whites Corner where we turned south passing through Neerim Junction, Neerim, Neerim South and onto the Princes Highway on the outskirts of Drouin. Then it was highway cruising to home is a rather muddy vehicle with two 4 point activations in the bag. Right: The view of the ranges from the VK3AFW operating spot.

APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 23 of 59 THE 2015 HAMFEST CONT’D As usual the Hamfest was held on the Saturday before Mothers Day. Unfortunately The WIA have taken to having their AGM on the same weekend, meaning some familiar faces were missing. This year door sales were up and the cool weather produced a run on the hot food and tea and coffee but few cold drinks were sold. The Cuppa and Chatter room was full most of the day—an excellent innovation. Kaye VK3FKDW and Denis VK3BGS manned the ticket desk and Brian VK3MCD collected the table charge from the traders. This year we had an excellent book stand by Peter VK3FPRS who is a keen SOTA chaser. Icom were busy fielding questions and most other traders di rather better than petrol money. The editor was sorely tempted to buy an old piece of Yaesu gear but fortunately someone else nabbed it early on. Corrie, Noel VK3BMU and Tony VK3CAT ran the BBQ with their usual flair. The weather was a bit cool but not wet so that probably helped get a good turnout. As usual eyeball QSO’s with friends seen face to face only at hamfests featured highly on most attendees agendas. Thanks to Graeme 3GL, Cohen VK3HCL, Lee VK3GK, Ian VK3IFM, Ian VK3XI and Gerard VK3GER for the “heavy lifting”.

APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 27 of 59 MARCH 2015 TALK This talk was on the setting up of a remote station by the Frankston and Mornington Peninsular Radio Club. The speakers were: Peter, VK3IJ, Colin VK3CR, and John VK3XM. According to their newsletters, FANPARC uses an Elecraft transceiver with 100watt PA. It has additional roofing filters, an automatic ATU and the two metre module. Members can access the club via the internet, switch on the radio, and switch between the hf beam or the dipoles for 30/40 and 80 metres. The control of the hf beam rotator includes an excellent piece of software which includes a world map, when members hear a call sign they simply click on the call sign for that particular country and the beam with turn to the desired direction, how simple is that? Unfortunately the editor was unable to attend and as no attendees responded to the call for feedback he stole the above from several FAMPARC newsletters. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 28 of 59 JOTT 2015 Our club was approached by District Joey Scout leader Murray Taylor VK3MJT to support the Jamboree of the Trail, JOTT on the 17th May 2015 and provide 3 stations on a walking trail along Gardner Creek Bike track. The walk started at Darling Station and continued to a turn around point at Burke Rd South Wetlands, some 3 km. The walk then returned to Darling station. Above: The Club Banner on display at the starting point.

We used 2m simplex and had good communications over the distance. The team were of varying sizes made up from Regional Scout groups with on average about fifteen Scouts and adults in each team. There were 19 teams of walkers. Our task was to radio times when teams arrived and left the two checkpoints on the track and returned to the Start. The mission was accomplished without difficulty. Above. The Start and Finish point. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 31 of 59 APRIL 2015 TALK Club Member digital photography Ian VK3IFM gave a presentation on .

He was then inveigled into talking about what it was used for.. It was part of an Automatic Gun Laying Turret—AGLT. It had a code name of Village Inn. See picture at right. This was before robots were part of most peoples imagination let alone reality. However it was in truth a robotic gun layer. Why was it needed? In WW2 the average number of flights survived by rear gunners in British multi-engine bombers was 3 sorties. This was unacceptable and unsustainable. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 33 of 59 WW2 ROBOT REAR GUNNER CONT’D The aggression and skills of the Luftwaffe pilots and their tactics were more than a match for most rear gunners, most of whom had limited training and no combat experience before their first flight. Seeing a fighter plane approaching with a closing speed of 300 km/h before it opened fire with cannons at a range of maybe 400 m was a difficult task. Remember the British bombers flew at night so the position of the moon and clouds were usually exploited by the fighter pilots. Right: the feed, counterweight and reflector. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 34 of 59 WW2 ROBOT REAR GUNNER CONT’D As the war progressed RADAR had become increasingly sophisticated. By 1943 it was possible to make a scanning radar and remote gun control small enough to fit where the rear gunner had been. The RADAR had a range of several km. Although using valves, mechanics and electrical motors the system could track a detected fighter and assist a remote gunner to bring the guns to bear on it. It was coupled to other equipment with which it functioned including means of detecting if the approaching aircraft was friendly or a foe. The drive motors and gearing for the rotating feed can be seen at the right. The microwave and other electronic equipment was separate. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 35 of 59 WW2 ROBOT REAR GUNNER CONT’D Left: Village Inn installed on an Avro Lincoln. The gunner was located in the main cabin. There wasn’t room for him in the turret anymore anyway. The Australian built versions did not have the radome assembly hanging on the gun turret but appear to have a smaller fixed radome presumably to house an updated Village Inn system. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 36 of 59 WW2 ROBOT REAR GUNNER CONT’D On the right is a photo of the feed. A balancing weight can be seen. This was to allow rapid scanning of the dish 2,000 rpm with minimal loading on the assembly. The feed is offset and spun. A 30 degree beam width was produced and drive motors gave elevation and azimuth movement. This swept the beam and gave a rapid view of the sky behind the aircraft. The RADAR operated in the 9.1 cm band. Although it was described at the time as an automatic gun directing radar it could be considered a robot with one task. To seek and destroy attacking fighter aircraft. Once an aircraft was detected on the radar the gunner had to move the guns so the aiming point coincided with the radar blip as displayed on a small CRT. He could also monitor IFF systems to avoid shooting down friendly aircraft.. Once satisfied it was an enemy and it was within range he fired the guns. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 37 of 59 WW2 ROBOT REAR GUNNER CONT’D On the right is another view of the hardware for driving the feed and thereby rotating the lobe of the radar to scan the sky.. The system was developed late in the war and only about 100 were built and deployed. They had a 90% kill rate, far better than a human only gunner. Conventional gun controls with the normal allowances for bullet trajectory were used. Components of the Village Inn systems are now extremely rare. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 38 of 59 WW2 ROBOT REAR GUNNER CONT’D Right The name plate/modification record. The stampings here are clear. It appears to record the various modifications incorporated in this unit. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 39 of 59 WW2 ROBOT REAR GUNNER CONT’D Thus the loss of airmen was reduced, the accuracy of defence improved over purely manual aiming and more bombers survived. Post war bombers of all nations were fitted with similar systems. Automatic aiming of airborne weapons systems is now standard although the pilot or weapons officer still has the need to decide to “fire” or not. Above: The name plate. One reference says the equipment was known as a TR3548 but the name plate says Type 83. The serial number, 1836 has not been well stamped and originally was stamped as 1835. The stamper seems to be inexperienced particularly compared to the Mod Plate stamper. APC NEWS Number 239 May—June 2015 www.mdrc.org.au The editor accepts responsibility for any errors in this article. Page 40 of 59 AERIALS AND STUFF The VK Windom Mk II The need for a Mk II version. The original article was published in Amateur radio magazine in January 1991 and republished on https://vk3afw.wordpress.com/. For the VK100ANZAC operation a basic multiband wire antenna held up by a self supporting mast was needed (no pegs or stakes allowed). The OCFD seemed the answer with a squid pole on a base held down by a 20 kg sandbag. It need cover only 7 MHz and up as the operation was in daytime. A lightweight antenna using “dx wire” was made but there was the problem of supporting the balun on a light weight fishing pole. The thought occurred that the antenna could be fed with 300 ohm ribbon and the balun placed lower down on the sturdier part of the mast. The 300 ohm feeder would have an SWR of less than 3:1 and as it was designed for VHF the losses would be negligible. The next thought was, was there a better length of 300 ohm feeder than just what fitted? How Long Should the Feeder Be? Typical OCFD feed resistances range from 90 to 250 ohms (depends on band and antenna height) with the lower value being at the lower frequency, in this case 7 MHz. A feed resistance of about 100 ohm feed resistance transforms up to 900 ohms if the feeder is electrically a quarter wave long, a bit too high. So the length should be shorter than a quarter wave on 40 m. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 41 of 59 AERIALS AND STUFF CONT’D A one eight wave length would increase the feed resistance to a higher value but acceptable value and would add some reactance. The SWR would still be 3:1 or thereabouts, well within he range of most auto-tuners. A one eight wave on 40 is a half wave on 20 m where the expected feed resistance is about feed resistance of 140 ohms transforms up to 640 ohms for a quarter wave length which would be a little higher than wanted. For 10 m the 125 ohm feed resistance would be unchanged if fed by a half wave length of 300 ohm feeder. The one eighth wavelength on 40 m equates to 8.4 m allowing for a velocity factor of 0.8. This length is a bit long for 20 m . Half this length is only just enough to get far enough down the squid pole for it to hold the balun but is a quarter wave on 10 m and pushed the feed resistance up too far. The average is 6.3 m and this was chosen as the compromise length that could be used with all the common squid poles.. The feed resistances are a compromise on 40, 20 and 10 but within reach of the average auto ATU when a 4:1 balun was used at the bottom of the 300 ohm line. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 42 of 59 AERIALS AND STUFF CONT’D What bands? With the wire cut to 7.1 m and 14.2 m before assembly, 40, 20, 10 m were expected to tune up easily and give acceptable performance. Now the 300 ohm feeder can also be considered as lengthening the antenna by 15 m to 36 m overall which is a bit more than a full wave on 30 m and three full waves on 15 m. So it might be possible to operate on 30 m and 15 m. As the 300 ohm feeder the feeder is a balanced line and fed by a balun little radiation from the feed line should occur thus the patterns on 30 and 15 m can be found from considering the 21 m radiator only. The other way of looking at it is that the feed line transforms the impedance of the OCFD on 10 MHz and 21 MHz to something within the range of the ATU. Did it work? In a word, yes. The ATU actually tuned the rig on all HF bands above 3.5 MHz. It’s effectiveness would be compromised on this band but should work better than a whip. There was a problem with a hot microphone but adding a ground radial fixed that. A 4:1 current balun instead of a voltage balun might also fix that problem. DX contacts were obtained from the set up in the Mentone Memorial Gardens on 30, 20, 15 and 10 m. Many very good reports were received from numerous VK’s on 40 m. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 43 of 59 AERIALS AND STUFF CONT’D Yes a beam would have been a big improvement but for a multiband compromise wire antenna this is hard to beat.

Harley was a long time member of the Club and he especially enjoyed the Tuesday Coffee meetings. He was a man of many skills who rose through the ranks to a senior position in the Gas and Fuel Corp of Victoria. He was often called upon to exercise his machine shop skills for other Club members and his chemical knowledge came to the fore when he made marmalade of show quality and brandied cumquats that were heavenly. Harley was part of a group who chatted every week afternoon on 2 m on their way home in their cars. This net eventually became more home based as members retired. It was known as Harley’s (drive time) net and continues today. His sagacity and friendliness are sorely missed by his friends at the Club. APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 47 of 59 OBITUARY ROLPHE VK3JWL Rolphe Thomas Fox, b 22/4/1925, d 2/4/2015. After attending Mentone Grammar Rolf joined the RAAF as a young man and spent his time after training as a RADAR operator at various coastal RADAR stations. Rolphe enjoyed a joke and could be relied upon to tell one at most Tuesday Coffee meetings. If he didn’t have a joke he would have a funny quip to make. This was a skill honed in his job as a sales representative for Hecla. In the 1950’s through to at least the 1980’s no salesman worth his salt would try to sell anything until he had made the client laugh/. Even when his battle with cancer was becoming more burdensome he was cheerful. His cheeky grin and quick wit are missed by his friends at the Club.

He had recently moved into Vasey RSL Community Care. Until then he had lived independently at home. Arthur was licenced as VK3QF in 1937 at 20 years of age and proceeded to work the world using 25 watts of CW and a Windom antenna. A year later he became a Certified Practising Accountant. He joined the WIA RAAF Wireless Reserve and was called up almost immediately hostilities commenced in 1939. Within a fairly short time Flight Lieutenant Evans was in charge of a wireless unit which included the normal communications function and an Interceptors section. The story of the latter has APC NEWS Number 239 May—June 2015 www.mdrc.org.au Page 49 of 59 OBITUARY ARTHUR VK3VQ CONT’D been recorded in the book The Eavesdroppers by Jack Bleakly. Some of Arthurs exploits have been recorded in OTN magazine, for example in the March 1996 and September 1999 issues. Arthur’s deployment included a lot of time around Papua New Guinea often setting up new stations as the allies moved forward. Arthur’s interceptor group was of course proficient at KANA the Japanese version of Morse code and all received messages were written down and passed to the intelligence unit. On one occasion one operator said to Arthur, something is up; we are all seeing a change from recruits operating the stations to professional operators. So well did Arthur’s men know the individual operators sending they knew when someone else used the key. New well trained men had joined the outposts. This information was passed directly to the intelligence office and was the first alert General Mc Arthur had that a Japanese offensive was building. Arthur returned to the family business Evan Evans making canvas goods and also flags and banners - Ivor Evans, Arthurs father was co-winner of the design of Australia’s Flag. Arthur was a stalwart of the canvas trade. Arthur was an avid player of squash, hockey, tennis and golf. He was a train enthusiast and loved to travel.

Gradually the numbers in the group dwindled away, leaving only Arthur. Arthur joined the radio Amateurs Old Timers Club (member No 179) soon after it was formed and served on the committee for many years, from 1992 to 2013 (?) mainly as Secretary & Treasurer or Treasurer. He was a long term member of the M&DRC and took up the role of treasurer of the Tuesday morning coffee meeting which he rarely missed. When in recent years he lost his driving licence he acquired a battery driven scooter and would travel on it the 4 km from home to the Club rooms and 4 km back. Arthur valued his independence. He was a regular attender at the meetings until 6 months ago when he was no longer able to drive the scooter. Whenever asked how he was his reply was always “Oh I’m all right”. generous and cheerful. His ready grin will be missed.
