Thank you for tuning in and enjoy the broadcast! -------------------------------- WWFF, SOTA, POTA and IOTA Weekly Wrap-Up Itâ€Ös been a busy week for VK7 activators, with plenty of parks and peaks activated across the state, a great effort from all involved! Angela, VK7AMP, and Tony, VK7LTD, visited the Malwoodâ€“Rokeby Hills Conservation Covenant, located in the Rokeby Hills near Hobart. This protected area provides vital habitat for several threatened plant species, including the Risdon peppermint and chocolate lily. Angela and Tony operated on the 40m, 20m, and 15m bands during their activation. Stuart, VK7FADZ, made the trek to the summit of Mount Field West, the highest peak in Mount Field National Park, situated around 64 km northwest of Hobart. Stuart battled tough conditions to make five contacts and earned 13 SOTA points for the activation. Praj, VK7MPB, and Kiri, VK7KLB, had a busy week with multiple activations, including the Wellington Park Conservation Area, Mount Wellington Summit, and Fossil Cove Conservation Area. Operating on the 2m and 40m bands, they achieved a combined total of 58 QSOs. Peter, VK7ZPE, Rodney, VK7HAM, and Al, VK7AN, completed their regular Wednesday activation at Den Ranges Regional Reserve, located near Pipers River in northern VK7, approximately 40 km north of Launceston. That wraps up another week, great work to the activators and hunters who keep supporting the programs come rain, shine, or hail. 73, Matt, VK7MAT -------------------------------- QSL News Inwards QSL Bureau Information The current list of QSL Cards held by the VK7 Inwards Bureau as at 11 July is in the email version of the Broadcast.

The main themes were: Single propeller aircraft from World War 2 Cats relaxing everywhere, even displacing Dracula from his coffin Famous DX operators from the Addams Family, the TV show from 1964 Clubroom presentations at REAST and NTARC Other highlights were: The word of the day is â€œHurkle-Durkleâ€, a 200 year old Scottish term for staying in bed A Morse code proficient carrier pigeon The similarities between a Rugby Scrum and a cat walking away from you Space Xâ€Ös latest unwilling passenger The latest design for the stadium using alternative structural supports David Bridie and Monique Brumby at the recent Festival of Voices Itâ€Ös not a competition from a crazy chicken Gary the Goose and his loose gas And 73 from hurkle-durking under the sheets Again Tony VK7AX interconnected VK7RJG to his SSTV International Gateway and VK7s exchanged photos with PA3EKI and PC1K in the Netherlands. Remember to leave a 30 second break between transmissions to allow the European countries a chance to send photos. Tony will connect the gateway again next week at 6:30 pm. Note - Ken VK7KRJâ€Ös and Steve VK7OOâ€Ös fully automatic 24/7 monitoring sites allow anyone who has sent SSTV pictures the ability to check them on their pages almost immediately, any time, both South and North Tasmania.

For more information contact Al on 0417 354 410. 73, Al, VK7AN -------------------------------- Northern Tasmanian Amateur Radio Club Incorporated www.ntarc.net Hopefully no one turned up at the NTARC Club Rooms last Wednesday night, because we had all relocated to the Iron Horse Bistro - for the clubs mid-winter social get together. We all gathered about six pm for what ended up being an evening of excellent food, served in pleasant surroundings, with friends. It may have been a social evening, but as usual, much of the conversation was interspersed with radio and electronics, as always! HiHi. A great time was had by all and we eventually made our way home thoroughly satiated. Friday morning tea came with an update from Trevor VK7TB, regarding a presentation earlier this month on crystal parameter measurements. Trevor brought in a plug in crystal test jig that he constructed fourteen years ago, consisting of an upturned printed circuit board with all the operational components fully accessible for soldering and tweaking, all mounted on top of a diecast enclosure which houses calibration and measurement switches as well as some external connectors. The test jig is complete with a sacrificial crystal socket and daughter board that can be replaced in case of any contact wear after testing many hundreds of crystals. The design is based on a paper published by Chris Trask, N7ZWY from Sonoran Radio Research in Tempe, Arizona, USA. Titled â€œA Practical Test Set for Comprehensive Crystal Testingâ€, published in 2008. This is considered to be one of the definitive papers on the measurement of series resonant parameters of a crystal. The circuit is based on a differential Butler oscillator which in this case allows for parameter testing and measurement in a linear, non-saturated mode. External measurement ports for his Vector Voltmeter and Oscilloscope are also buffered from the crystal under test. The beauty of this particular design is the very high level of accuracy and repeatability of measurements. This confidence in results is paramount for the selection of crystals, to a very close tolerance, for the implementation of a ten pole ladder filter Trevor is designing. For interest there is high end commercial test equipment by Hewlett-Packard / Agilent and others that accomplish the same result, however with a test jig like this you can test at a similar level of accuracy. The use of this type of â€œtest jigâ€ certainly is more labour intensive and slower but comes with the added bonus of not having to mortgage your house to afford the piece of Agilent test equipment. No doubt after a couple more hundred crystals are tested for his ten pole ladder filter project, Trevor will update us as to the progress. As always pictures will be available on the NTARC Web site under â€œBlogsâ€ for this broadcast.

Thatâ€Ös all folks, 73 from Stefan, VK7ZSB, Secretary NTARC Inc. -------------------------------- NEWS FROM THE SOUTH Radio and Electronics Association of Southern Tasmania https://www.reast.asn.au/ https://www.facebook.com/reasttas/ https://www.youtube.com/reasthobart/ July Forum Night Logging, paper, pen, computer or memory? https://www.youtube.com/live/crjRJRCbKdo?si=viWetGdf1rfgGKit The July REAST Forum Night tackled a topic familiar to every amateur radio operator â€ö logging. The session featured a rapid-fire showcase of logging tools and techniques used across the VK7 community and beyond. Participants shared their preferences for everything from modern digital platforms like HamRS, VKPortalog, Log4OM, N1MM, and Ham2K, to the classic pen-and-paper methods. Several operators described hybrid approachesâ€öusing paper logs during activations and later transferring data to digital systems like VKCL, ClubLog, WSJT-X, eQSL, and Excel. There was also discussion of log compatibility, ADIF and Cabrillo formats, lazy logging, and ideas for managing contest data, satellite passes, and phone power consumption during field ops. The forum also delved into legacy systems (like TRS-80 and DOS-based loggers), the need for a modern, open-source replacement for VKCL, and emerging ideas like using AI in logging and creating a centralised REAST Wavelog database for members to share logs and enable real-time scoreboards. There was enthusiastic talk around log backups, data portability, and interoperability between platforms, along with nostalgia from the days when contest results took a year to arrive. The evening wrapped up with strong support for innovation in logging, combining automation, portability, and modern interfaces with the solid foundations of amateur radio record-keeping. Thanks to all who contributed to the Forum. 73, Justin, VK7TW https://www.youtube.com/live/crjRJRCbKdo?si=viWetGdf1rfgGKit -------------------------------- VK7 Broadcast News Trial 11m Rebroadcast Stephen VK7SME has put his hand up to trial an 11m HF CB Channel 24 rebroadcast on a Sunday morning and Tuesday night for the Hobart area. The frequency of channel 24 is 27.235MHz and the mode is LSB. Stephen will be taking callbacks. Thanks to Stephen and help from Mark VK7FMAC for getting the broadcast out on another frequency and demonstrating what amateur radio can do. We are currently building a patch box for Stephen which will further improve the broadcast quality on this band. 73, Justin, VK7TW -------------------------------- Wednesday Experimenterâ€Ös Group (WEGs) We are back in the studio this Wednesday night (July 16th) with a full show of experimentation and interesting AR related information. Over the next three DATV nights, in no particular order we have lined up: Telegraphy - morse comms from a bygone era Telephone exchange simulation Trans-Tasman Low Band preparation and experiences VK7 Preparation for the RD Contest Kenwood MAT-100 ATU reverse engineering AR, Low-Key and DUBUS Magazine reviews Final ADX calibration (out in the clubrooms) Something non-AR related topics: All about blood and blood/plasma donation with 7TW and 7BEN Tour of our new studio, clubrooms and the AV behind it On a Wednesday night people start arriving at the night around 6pm and many bring their dinner to enjoy. There is always much discussion, experimenting, playing, talking, drinking coffee and tea, serious cunning plan development and general amateur radio shenanigans and world problem solving in the clubrooms as well!! We stream the nights on the REAST YouTube streaming channel. See you there or on the stream. 73, Justin, VK7TW -------------------------------- August Presentation Night Antarctic Diary Recollections https://www.reast.asn.au/event/reast-presentation-antarctic-diary-recollections/ August will see a very special historical presentation from Andrew Johns VK7AJ about his Dadâ€Ös Antarctic Diary from the International Geophysical Year in 1957. The diary was unearthed in a box at the South Hobart Resource Tip Shop and traced back to Andrew (thatâ€Ös a story in itself!!). David Johns VK0DJ/VK1DJ/VK7DJ headed south to Macquarie Island in 1954 and then to Mawson in 1957 for the Geophysical Year which started in July 1957 and ended in December 1958. The aim of the International Geophysical Year was for the simultaneous collection of data on a world-wide basis to take place and Davidâ€Ös physics role was to gather data about cosmic rays. There is some wonderful insight into life in Antarctica in 1957 and many stories will be told. When: Wednesday August 6th, 2025 from 7:30pm Where: Queens Domain Clubrooms and streamed on the REAST YouTube stream See you there or on the stream. 73, REAST Committee https://www.reast.asn.au/event/reast-presentation-antarctic-diary-recollections/ -------------------------------- August Forum Night - Favourite Digital Mode https://www.reast.asn.au/event/forum-night-favourite-digital-mode/ Join us for an engaging REAST Forum Night on Wednesday, August 6th, where we dive into the world of digital modes â€“ the ones you love, and the reasons why!

These balloons are one use devices and the balloon eventually bursts and the radiosonde comes back to earth on a parachute. They have a lithium battery and we will have some examples of them at the presentation. They transmit on the 75cm band and can be picked up using a modest receiver and antenna. Some amateurs have even repurposed the transmitters for amateur beacons on 70cm. They are tracked through a citizen-science project called SondeHub that Steven VK7SH has been deeply involved with. https://sondehub.org/ There is also a historical club linkage with radiosondes with Rex Moncur VK7MO developing some early valve based radiosondes back when he started with the Bureau of Meteorology. When: September 3rd, 2025 from 7:30pm Where: Queens Domain Clubrooms and Stream on the REAST YouTube Streaming. https://www.reast.asn.au/event/reast-presentation-weather-balloon-chasing/ See you there or on the stream. 73, REAST Committee -------------------------------- September Forum Night How to get the most from your NanoVNA https://www.reast.asn.au/event/forum-night-how-to-use-your-nanovna/ Everyoneâ€Ös got a NanoVNA in their shack (except Rexâ€¦HIHI!)â€¦ but are you really getting the most out of it?
