WIA Spring VHF/UHF Field Day

Well it's time to clear the dust and spiders from the portable VHF and above equipment and get ready for the WIA Spring VHF/UHF field day. This year it will be on from 01:00 UTC Saturday 26  through till 00:59 UTC Sunday 27 November 2022. There are a number of sections and then sub sections so there is something for everybody. Broadly speaking there are two main streams of participants, those that are happy to pack up a fair bit of their shack, associated bits and bobs, then reassemble it in some remote spot, discover they have forgot to pack "something", brave or enjoy the weather and conditions, supply power, make some contacts then do the reverse and pack it all up take it home, and those that are not quite that mad and operate from the comfort of their shack. Then there are the Rovers. They are special individuals as they move about and repeat the portable things all over the place.

There are sub sections that are aimed at the new licensees as well, like the single band section, or the 4 band section that covers up to 4 of the traditional VHF/UHF bands. There is the option to work either 8 hours, or the full 24 hours.

It's a great day of fun and  there will be many people out and about so why not allocate some time to come on and exchange some numbers that weekend. You can rework stations after 2 hours. The usual logging programs like VKCL, YACL and others will keep your contacts logged just don't forget to check the time is correct and that you check all details before hitting the "log" key as a small error will cost you a contact. You will need to determine your 6 digit maidenhead square locator from your operating location, there are many smartphone apps to help obtain this.

The places to look for contacts are the following.

6M - 52.525 FM, 2M - 146.500 FM, 70cm - 439.000 FM, 23cm - 1296.150 FM, 13cm - 2403.150 FM, 9cm - 3398.150 FM and on 3cm - 10,368.150 FM

Checkout the WIA website for all the rules and other information.

https://www.wia.org.au/members/contests/vhfuhf/

If anyone would like some help with any aspect of the field day I am happy to offer assistance, along with the wealth of knowledge and experience of other members, just reach out and well do what we can to assist.

Here's hoping for a great Spring Day, hear you on the bands.

Statewide News
Thursday Night SSTV Nets

Another great night that saw the following participants VK7s – ZAB, FGGT, ZSB, ZIR, WP, ZCF, ZBX, PAK, YBG and TW all sharing over forty photos.

This weeks Science Fiction contribution was from “Doctor Who” with a topical Daleks photo and the “Thunderbirds”.

This weeks TV sitcom photos where from “Faulty Towers”, “Some Mothers do “Ave ‘Em”, “The Good Life” from 1975 and “Green Acres” from 1965.  .. For those that recognise these images, is it making you feel a bit old?

There was a strong interest in vintage items like: radio equipment, 4 wheel drive vehicles, cars and tractors. Also the weird “Red Sands Sea Forts” at the mouth of the Thames Estuary which were constructed during the Second World War. Other interests were travel, birds, pet cats, various test patterns and ending with “42, the Meaning of Life”.

A reminder in Southern Tasmania, VK7RAF (146.650 -600kHz) can be used both locally and linked to VK7RJG by using different CTCSS tones. 123Hz for local Southern operation and 141.3Hz for linking RAF to VK7RJG (438.55 -7MHz). No tone is required on VK7RJG to connect with VK7RAF from the North and North West.

We get underway from around 7:30pm.

Bar B Que and Fox Hunt

A Bar-B-Que and Fox Hunt is to be held on Saturday the 22nd October  2022.

We plan to start with a Bar B Que commencing at Midday at Legion Park, which is off The Esplanade behind the Showgrounds at West Ulverstone. 

Legion Park is accessed by turning East into Maud Street off Queen Street, taking the road to the river and BBQ facilities. 

This is a BYO food & drinks event and there are two electric BBQ, toilets, running water and some seating and tables under cover on site. 

At 2pm, if there are sufficient numbers, we will commence the Fox Hunt, which will be along the style of the old-fashioned CB Fox hunts, where the Foxs hides, and then the chasers using signal strengths and clues, attempt to locate the Fox. 

The person who finds the Fox, then goes and hides, and we start the chase again. To assist any amateur to participate, it will be run on Channel 50, 146.500 MHz and operate in the Ulverstone Township. 

We will continue while there are chasers for the Fox. If the weather is inclement, Eric VK7EV will be on 2m VK7RMD in the morning, to advise if event is still proceeding. If canceled we may reschedule to the following Saturday.

We will begin this week with an update on Wednesdays Tech Night session, the last for September! Stuart, VK7FEAT had Luke Sky Warmer stoked up with kindling and ablaze in double quick time. Not sued it was yet another immaculate restoration job of his, but according to Ross it was virtually new ex-stock and thats how it arrived. After fifty years it has finally made it to Rosss Retirement Home for elderly radios.

Andre brought along his latest acquisition a Transmit or Receive switch unit from MFJ, model 1708B version SDR. It can be used on a pair of Boat Anchors as the receiver and transmitter switch, or with a transceiver and SDR sharing the same antenna.

Its designed to fit inline between a transceiver and antenna while also providing a safe split of the antenna signal to a dedicated receiver or SDR. Andre tested it earlier and can confirm it was a true split and that the transceivers receive function worked with no noticeable drop in signal strength.  The unit is designed to be controlled ideally from the PTT output of your transmitters. It also uses RF detection of the Transmit signal to control the switching, with the SDR input being further protected via a clamping diode array. 

The enclosure was quickly pulled apart to reveal a well-made unit. Andre down loaded the user manual from the manufactures site but could not find any technical data sheets. From the user manual a note says that the unit should not be used with transmitters over 200W and quote “has excellent isolation between Transceiver and SDR Receive ports” and “Good SWR characteristics up to 450MHz”. This was the only reference to the units frequency range. 

Andre was unable to obtain this unit or the SDRplay in Australia. Luckily a popular UK ham radio outlet stocked them and amazingly they arrived in less than 10 days.

www.HamRadio.co.uk

Note: The Model 1707 looks similar but is designed to switch a transceiver between separate TX and RX antennas. Andre thought it a good idea to try and protect his SDR, even a manual antenna switch has deadly leakage when transmitting.

Update on last weeks breaking news - Peter, VK7KPC has received a certificate from the Radio Society of Great Britain (RSGB) in the IOTA Contest for 2022.  He achieved 8th Place in Non-UK Station Single Operator Section for NON-DXPEDITION / MIXED MODE / QRP. 

According to the IOTA web site the contest was: "Established in 1964, it promotes radio contacts with stations located on islands around the world to enrich the experience of all active on the amateur bands and, to do this, it draws on the widespread mystique surrounding islands." This description seems to encourage expeditions to IOTA islands to "Activate" a temporary Amateur Radio base camp for this contest.

https://www.iota-world.org/

The contest is administered by IOTA Ltd in partnership with the Radio Society of Great Britain (RSGB) and is held the last full weekend in July over a 24 hour period.

Contest bands are 80m, 40m, 20m, 15m and 10m, with both SSB and CW used.

While we are congratulating Peter on his activities, his callsign also appeared in issue 5 of Amateur Radio under “2022 VK Shires Contest report”, Peter had taken out First Place for VK Single Operator, 10 Watt, All Band, All Mode category of the contest. For more details we have covered this success in a previous broadcast in July. 

Now, you may have heard that things come in threes, in this case good things. Still in AR magazine Peter, yes the same Peter! was also mention in the article titled, ” Harry Angel Memorial 80m Sprint – Results 2022”. Peter was one of two VK7s that submitted logs to this 80m contest. This contest is in memory of Harry Angel, VK4HA and according to AR magazine, “at the time of his becoming a Silent Key, was the oldest licensed amateur in Australia”. That in itself is an achievement. I must admit this event surprised me as the contest only goes for 106 minutes! Yes not even 2 hours! I can now see why it was called a sprint. Evidently there is one minute of contest time for each year of Harrys life. That explains things and in that case he did indeed reach a good age and would have hopefully received his letter from the late Queen. Congratulations to Peter and the only other VK7 participant, Catherine VK7C, for waving the flag. 

Thanks go to Rick VK7HBR, for stepped into the breach at short notice and very capably taking over the position of Net Controller for Wednesday nights Tech Net Session. From the sound of the atmospheric noise intermittently emanating from the Club radio room, while Ross was participating, it may not have been an easy session and band to work with, especially going in cold. Either way well done and thank you Rick.

JOTA/JOTI for 2022 volunteers to assist are needed! 

The Venue is the NTARC Club rooms, which is the Rocherlea Scout Hall, Archer St, Rocherlea.

The sessions will be on Saturday the 15th of October from noon to 6pm and Sunday the 16th October from 10am till 3pm. Groups are planned to arrive in two hour blocks, split up and rotate through four activities.

At the Club Rooms we will need volunteers to assistance with:

WICEN Tasmania (South)

WICEN South are in need of some help.

We are tasked with providing safety comms and rider progress reports for the Portland Equine Endurance Ride at Pyengana on Saturday 15 October.

You may have realised that this date is also the JOTA/JOTI event.

A lot of our regular helpers are down to assist with JOTA and therefore we are really in need of help to man the Checkpoints for the Ride..

If any amateur or listener can see themselves as being able to assist by calling the rider numbers as they pass, then we would welcome your assistance. A pat of a horse and a pass of a sweet to a rider or two, are also on the cards.

We can offer an active couple of days, some great scenery and a chance to have a meal at The Pub In The Paddock. Your reward is knowing that you are helping the riders to test themselves while caring for their mounts at the same time.

Please contact Rod Finlayson, VK7TRF on 0417314425, or email roja3kel(at)yahoo.com.au for further details.

DATV Experimenter's Night

https://fb.me/e/1MughsG2V

We started the night with Justin VK7TW showing Miguel VK3CPUs wonderful online application to play with different designs of magnetic loops.

https://miguelvaca.github.io/vk3cpu/magloop.html

Justin went through the different elements including loop diametre, size of the loop material, loop resistance and other elements that can be entered with sliders for each parameter. After entering the parameters there is a realtime plot of each parameter for the frequencies covered and it includes pop-up boxes for all parameters for each amateur band.

Justin then showed some design ideas using PVC pipe.

We then went into the inductive coupling options including shielded and un-shielded coupling loops, Gamma Match - auto transformer, hairpin and twisted gamma (spiral) and T-Match (dual gamma). There is also capacitive coupling and magnetic Coupling - toroid around the loop with coupling loop
