NORTHERN TASMANIAN AMATEUR RADIO CLUB INCORPORATED 
As this news goes to air, many NTARC members will be packing up their kit and heading home after attending the Jill Sheean Memorial Endurance ride held at Sassafras yesterday. I dare say that Norm VK7KTN, our Safety Communications Co-ordinator, will have a report on that event in next week’s news. 
Update July general meeting – Last Saturday we held our July BBQ meeting. The fire had been lit earlier in the morning by Ros and to augment that, the big workshop gas furnace was fired up to bring the main hall up to a balmy temperature of 17 by the time the meeting commenced. 
Considering it was a cold morning, we had an extremely good roll up of 19 for lunch, with our cooks Idris VK7ZIR, André VK7ZAB and Stefan VK7ZSB cooking up the usual variety of meats. Again as usually occurs these days, the meat was accompanied by various salads and hot vegetable dishes, provided by our lady members. The garlic bread seemed particularly popular too. 
The meeting commenced on time at 14:00 hours (2.00pm) and the agenda was quickly worked through with the meeting being closed at 14:20 hours (2.20 pm). Even by recent standards, I think this may have been a record for us. Items for Show and Tell were limited so afternoon tea was set up and general chat took over. We must again thank our lady members for providing the goodies for afternoon tea. 
Given the brevity of the meeting, the minutes shouldn’t take me long to write up, once I recover from babysitting grandchildren over the school holidays and of course, also getting over this weekend’s equine event. 
Report on Wednesday 18th Technical session 
Idris reports….. 
“As the old ditty goes “The night was dark and stormy, the billy goat was blind…..” 
Although this Wednesday night was definitely dark and stormy, we didn’t have to contend with any blind billy goats or barbed wire fences, and so it was a goodly number of hardy souls that rolled up for the weekly tech session. 
First in lit the fire and got the urns going, so by the time others turned up, they could enjoy a hot cuppa and a warm by the fire. 
Ross VK7ALH brought in a Drake T4XB transmitter in beautiful condition. There were many admirers of the quality of the build and the fully copper plated chassis. Of particular interest was the clever mechanical mechanism to operate the band change function, saving space on the chassis. 
Kevin VK7HKN brought his magnetic loop antenna being fed with an FT817. This drew attention from John VK7FJFD and Bernie VK7BR. When tested with an antenna analyser, it was found to be resonant at 7 and 14MHz with almost perfect SWR. 
Flushed with success from last week’s triumph, our intrepid computer team of Kevin VK7KJL and Simon VK7FSRM, decided to tackle six more pre-loved computers. They managed to get two operating from the six, very useful for the Club. Well done again boys! 
Colin VK7ZCF and Peter VK7ZPE were discussing oxy-acetylene containers, no – I don’t quite know why - and Peter VK7PD arrived and was soon discussing our roof mounted antenna system. 
Idris VK7ZIR presented a fine example of a Yaesu FT7. Ross VK7ALH had the cover off quick smart, and proceeded to point out various tips for improvement. Thanks Ross. It was interesting to see the plug-in modular construction in a radio of such age 
Meanwhile, Ebenezer VK7AT, used the signal generator in the Electronic Workshop to test the frequency range of his very nice, pocket sized digital short wave receiver, which exhibited very good selectivity and sensitivity. 
And finally, Stuart VK7FEAT arrived with a very interesting home brewed item, which had everyone talking! 
I will say no more!” 
Thanks Idris for that update. Glad to hear the club room hadn’t been invaded by blind goats! I remember all too well the damage goats can do, don’t I Alvin? You have us wondering what Stuart’s interesting home brewed item was. Guess we will have to be patient and wait for further information but what makes me think it might have been in a familiarly shaped glass container? 
Now on to Coming events… 
Technical sessions –Wednesday 25 July from 7.30 pm to 10.30 pm, at the Club room, Archer Street, Rocherlea. Interesting date - now just 5 months to Christmas. 
August General Meeting – to be held on Wednesday 8th August at the clubrooms, Archer Street Rocherlea. An evening meeting, to commence at 19:30 hours (7.30 pm). Show and Tell or a presentation, if we can rustle up one, to follow and then supper. 
Social Dinner 
Wednesday 22 August. As in previous years, the venue will be Steve’s Bar and Grill, Launceston. Meet time 6.30 pm for dinner at 7.00 pm. This catch-up dinner has proved very successful for many years. If you are planning to attend could you please email me at either of the following addresses ypmaxwell@bigpond.com or ntarc.emails@gmail.com or let me know at coffee sessions. A number of people have already advised me of their attendance. 
Future events 
September BBQ meeting to be held on Saturday 8th. BBQ to commence at noon, general meeting to follow at 14:00 hours (2.00pm). We are awaiting confirmation of our guest speaker and we should be able to confirm this in next week’ news. 
Coffee mornings – are held every Monday and Friday in the NTARC Club rooms. Catch up time is from 10.00 am to noon
Please remember that aside from the good company, freely offered philosophical views, maybe less than expert political analysis, tall tales and genuinely good fare on offer, these coffee events are normally a good opportunity to collect your QSL cards and we do have some cards awaiting collection so why not call in and see if any belong to you on a Monday or Friday
Please demonstrate your appreciation of all the effort that goes into operating the club and its facilities and other services we provide by joining us at these sessions, enjoying the company, coffee and the cake and leaving a gold coin or two, or even a small bank note, in the jar to assist in our on-going operations. 
Finally 
As always, I look forward to seeing you all at Rocherlea. A reminder to all members that if you have any items of news you would like added to the weekly roundup, then please email me at either of the following addresses ypmaxwell@bigpond.com or ntarc.emails@gmail.com

Experimenter's Night 
It was windy and wet however this didn't deter people from coming up to the experimenter's night - standing room only again! 
We welcomed Rex VK7MO back to the state after his Grid Square activation extravaganza! Rex has over 150 grid squares on 10GHz EME these days and we came to the conclusion that he is addicted to grid squares. This was after his explanation of what happened after the WIA AGM. Rex commented that he left the Gold Coast and thought, "I'll just do the next grid square" and after that he thought "I'll just do the next grid square". Well Rex then found himself only 30km from the tip of Cape York hihi! Thanks Rex. 
John VK7FPJA bought along a dynamic desk mic that Sam recognised from his Jaycar days and we discussed how to wire it up for use on a rig using the dynamic mike and push to talk. 
Justin VK7TW soldered together a 50 ohm dummy load kit from the Adelaide Hills Amateur Radio Society and this became the door prize for those who attended. This dummy load uses low inductance carbon 3watt resistors and two pieces of PCB that had been drilled to take the 11 times 56 ohm resistors. The finishing touch was a panel mount BNC connector. Paul VK7FPCL was the lucky recipient after Justin gave everyone a number and then found a random number generator on his smart phone. Congratulations Paul. 
Justin then took his homebrew 10GHz low noise preamp apart to try and work through why it was not amplifying. This design was a by a French amateur F6CXO and was published in VHF Communications in 2004 and was featured by Ralph VK3WRE in 2012 at GippsTech. Justin checked the driving and bias voltages and all seemed to check out. It was only when Justin got the unit home that he realised that he had labelled the input and output SMAs the wrong way around! Really must pay more attention next time...HIHI! 
The DATV studio received a good sorting out and we now have a pile of equipment destined for the resource tip shop. 
We get back underway with our experimenter's nights this Wednesday night from 7:30pm so, if you have a project or question then we certainly have answers and a hot soldering iron. We may even have another door prize for a lucky attendee. 
See you there. 
73, Justin, VK7TW

FROM SOUTHGATE AMATEUR RADIO NEWS 
Ham radio is socially useful 
"Outlook India" magazine interviewed Ambarish Nag Biswas, VU2JFA of the West Bengal Radio Club about how Amateur Radio is socially useful. 
Ambarish and quite a few members of his team had headed to a remote island at the confluence of the river Ganga and the Bay of Bengal. There, a couple had desperately sought his help in tracking their missing six-year-old daughter. “Among our club’s major activities is locating lost persons,” Ambarish says. The technical expertise of the club’s radio operators is in high demand from detective agencies trying to crack cases. 
In the above case, WBRC received an urgent message from detectives after they were approached by the girl’s family. Once the club members reached the site, they immediately set up a ‘radio zone’ within a stipulated radius. That was done by sending out team members in different corners with their radio transmitters as well as transceivers—a device that can both transmit and receive communications, and shares a common circuitry. 
“Our key function is to establish radio networks in order to communicate between ourselves (if there is a lead) as well as to intercept conversations,” explains Ambarish. “In a large number of cases, the missing person is a victim of kidnapping, trafficking or other crime. There is almost always communication between the members of the criminal gang who don’t use traditional methods of communication such as cell-phones which are not difficult for the police to tap into. Our radio network, operating at several frequencies, is like a web picking up the minutest sounds travelling through the spectrum.” 
Among the conversations intercepted, WBRC’s trackers heard a woman’s voice setting up a meeting point to “deliver” the girl. They located the source of the signal and informed the police. “The girl was being abducted,” says Ambarish. “But she could be rescued using radio signals to tap into her captors’ conversations.”
