Dick Smith VK2DIK
Ham Radio DX

Dick Smith, VK2DIK has lived an adventurous and extraordinary life. He is a proud Australian, businessman, adventurer, entrepreneur and he single handedly changed electronics and the Amateur Radio and CB scene in Australia.

Dick has recently released his autobiography titled, Dick Smith: My Adventurous Life and on Friday November the 19th at 8pm AEDT, we're privileged to sit down live with Dick on the Ham Radio DX YouTube channel. We'll be speaking to him about his adventure stories, including the first solo helicopter flight around the world, his business ventures and his early days and interest in radio.

Many of you listeners would have fond memories of walking into a Dick Smith Electronics to get the latest component for that project you are building, Funway kit, or maybe just to drool over that new rig! Yes this is the chance for all hams and electronic enthusiasts around Australia to say thanks to the legend that is, Dick Smith.

Attendance at coffee on Friday was another excellent roll up, although the cold weather put paid to last week’s thought that Sky Warmer could go into seasonal recess. His services were again definitely required to keep us all warmer than the outside temperature. Again, there was lots of chatter, although notably there were some technical issues discussed at one table. Many of us talked about the opening of the border on 15 December and how that could affect us. A number mentioned they were already booked in for early December to get their booster Pfizer vaccination. A related discussion topic was the suggestion of getting a copy of their vaccination certificate downloaded to their smart phone or failing that, running off a hard copy to have on their person at all times to show vaccination proof at venues, just in case that became a requirement. It is already a requirement in some States.

As this news goes to air a number of NTARC members will slowly be recovering from the State Championship Equine Endurance Ride held at Merseylea. The ride was a 24 hour event commencing at 00:00 hours Saturday. Hopefully the weather was kind to them as I can assure you sitting up in a chair wrapped in a blanket, waiting for horses to appear through the darkness is not all that comfortable in the cold and wet. The one advantage of the poor weather is that you can hear the horses coming for some kms and the twinkling of the rider’s helmet lights through the trees is a welcome sight to the check point crew as you slowly tick them off the list. We should be able to provide you with a full report in next week’s broadcast news.

As this was the off week for the club Tech night and no other news has reached the NTARCs northern reporter, we now move on to a rehash of upcoming events. I will understand if you decide to paddle off to the kitchen and make a cuppa and cook some toast. Before we go to events though, a little reminder that Christmas is drawing closer. Thanks to modern technology, otherwise known as the Internet, I see that there are 41 days from today to 25 December, so best get shopping and maybe start thinking about putting up the Christmas tree.

2022 Membership fees – yes with the year rapidly disappearing it is time to start reminding all that your 2021 Membership fee expires on 31 December. A letter advising of the fee payable for 2022 will be forwarded to all members in late November to the email address noted on our records.

We confirm that the 2022 membership fee will see a slight increase to $40 for each voting member with an additional unchanged $5 for each member of the family that the voting member wishes to add to his or her membership.

UPCOMING EVENTS

TECH NIGHT – Wednesday 17th November at the NTARC Club rooms, 19:30 hours until whenever. 

TestNet and TECHNET – Wednesday 24th November. TestNet/CW course on 3580 from 7pm till 7.30pm….and a TECHNET on 3567 from 7.30pm till about 8.30pm. Your host for the evening will again be Nic VK7WW.

Christmas Dinner – Wednesday 15th December. Venue Mowbray Hotel, meet time is 6.00pm. Tables have been booked under the name of NTARC. Menu is a-la-carte and there is plenty of parking at the rear. Please RSVP the secretary at either of these email addresses news(at)ntarc.net or ypmaxwell(at)@bigpond.com or jot your name down on the sheet next to the sign in register on a Wednesday night session or coffee morning. We will need to confirm final numbers with the Hotel on Tuesday 14th December, so please ensure you get your name on the list before that date. As of Friday we had 26 names listed and the Hotel has been advised to extend seating numbers to 30, so if you are planning to attend please advise so that your name can be added.

COFFEE MORNINGS – currently held every Friday in the NTARC Club rooms. Catch up time is from 10.00 am to noon and we look forward to seeing you all.

These coffee events represent a good opportunity to collect your QSL cards. We currently have cards awaiting collection, so why not pop in and check the QSL box and join us for a cuppa and chat.

Just a friendly reminder, please demonstrate your appreciation of all the effort that goes into operating the club, its facilities and the other services we provide, especially in these abnormal and very trying times, enjoying the company, coffee, biscuits and cake, by leaving a gold coin or two, or even a small bank note, in the jar to assist in our on-going operations. 

FINALLY – A reminder to all members that if you have any items of news you would like added to our weekly roundup, no matter how trivial, then please email me at the following address news(at)ntarc.net all items to be received no later than 17:00 on the Friday prior to the Broadcast.

Your continued cooperation in this regard will be greatly appreciated.

We will bring you all such contributions next Sunday morning.

DATV Experimenter's Night

We started the night with a recap of what resonance is namely, it describes the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force is equal or close to a natural frequency of the system on which it acts. When an oscillating force is applied at a resonant frequency of a dynamic system, the system will oscillate at a higher amplitude than when the same force is applied at other, non-resonant frequencies. Natural frequency - is the frequency at which a system tends to oscillate in the absence of any driving or damping force

Justin VK7TW then showed a large natural quartz crystal yes just Silicon dioxide but is essential and used extensively throughout the RF industry. Some history first with Peizoelectricity that was discovered back in 1880 and then used in WWI with quartz resonators appearing and then in 1920-30 quartz oscillators and clocks were created with accuracies of up to 1 second in 30 years!

A crystal is just a substance made from regularly ordered arrays of atoms, molecules and ions and Justin showed some crystallography books on Quartz that showed the quartz crystal molecular form. What we have learned from our previous shows on resonance is that the size, shape, elasticity, and the speed of sound in the material will determine the resonant frequency of the material when there is external energy applied to the system and this is no different in a crystal.

It was found that if you slice the quartz crystal in a particular way and apply an electric field then the crystal distorts called electrostriction or reverse peizoelectricity. As the crystal returns to its original shape it generates a voltage.

The specific characteristics depend on the mode of vibration and the angle at which the quartz is cut (relative to its crystallographic axes). https://en.wikipedia.org/wiki/Crystal_oscillator

Justin showed Ian Ridpath’s book again as it shows some of the different cuts of Crystal.

He then showed some of the many types of Crystals and opened one up to show the crystal and plates arrangement.

Justin then used the Gate Dip Oscillator to measure the resonant frequency of crystals at resonance. Next week I will have a jig made up for the NanoVNA.

Crystals can also be used as high Q filters and Peter Parker has a great video on that.

The DATV Experimenter’s night then moved to a picture thanks to Warren VK7WN which is a picture of Prince Charles on HF radio talking to Antarctic Bases when the Kingston AAD HQ was opened 40 years ago. We were helped out by Alan VK7KAJ, Roger VK7ER, Kim VK7KB and Herman VK7HW.

Herman VK7HW recollects that the call was mentioned in the Casey April 81 Newsletter. Looking at the Collins equipment being used, instead of Radphone call it must have been a call on one of the Antarctic Division frequencies. At the Casey end we probably used one of our main 10kW transmitters. We did have Collins gear as shown for our emergency comms - 1kW. 

The 40 years anniversary of the AAD reminded me -  I was at Casey Base in 1981 VK0HW. We received a call (Radphone) to get the OIC to the comms centre as Prince Charles was going to speak with him. It was about the official opening of the Kingston HQ. I left for the Antarctic on the Thala Dan from Melbourne where the HQ was at the time. Came home in early 1982 to Hobart where the new HQ was by then.

Thanks to Warren, Alan, Roger, Kim and Herman for sharing their Antarctic experiences.

Justin and Steve VK7OO then showed their latest 3.4GHz experiments with the new 27dBi grid packs along with pictures. Thanks Steve.

We finished with reminders of the up and coming events.

This week at the DATV Experimenter’s night we continue our focus on RF resonance, more Crystals, resonators, frequency standards, more 3.4GHz experimentation and much more. It will be coming to you from the Queen’s Domain clubrooms and we get underway from 7:30pm.

Keep an eye on the REAST Facebook Events for more details. 

And a reminder that we go out on RF on 445.5MHz DVB-T 7MHz Standard Definition. So, if you have a TV, Set-top box or USB DTV Dongle that you can tune and scan 445.5MHz and you can see the Queens Domain, then you have a good chance of receiving the DATV Experimenter's Night Signal.

Look out for VK7OTC. We also stream the nights on the REAST YouTube channel.
