Over the last couple of months there has been a noticeable degradation of the VK7RAD 2m Analogue FM repeater, with increased noise and crackling on the audio, and people requiring more power to get in to the repeater.
Additionally the club had been loaning a Bushcomm SWC-100S Antenna from VK7FAZE for 3 years, but it’s power limitations for non-SSB transmissions meant it was also time for a more permanent antenna to be procured and the loan returned.
A TET Emtron ED-52c was purchased as a replacement multi-band HF antenna and a Diamond X50N and these were installed last weekend, where it was discovered that the Heliax feed line to the repeater antenna was damaged, and it too has been replaced.
All up, a good 3 hours was completing the necessary maintenance and has been well worth it, with many users of the repeater mentioning the improved quality of the signal and Dave VK7DM is also reporting that where he used to need 40 Watts to get into the repeater with a clean signal, he now needs only 1 Watt!.
Thanks to VK7s SD, ZMS, ZBX, ZCR, FPCL and BEN for their assistance on the day with the maintenance work!
The observant will have noticed that our last post was in November 2018. This certainly doesn’t mean that the club has been shut down since then, there has been a lot going on and we just haven’t had time to update you on the website!
That is now changing, and we will be getting you up to date with all the happenings over the coming weeks!
Today REAST held a Radio and Electronics car boot sale and BBQ as an opportunity for members to sell some things to raise funds for the upcoming Miena Hamfest as well as being an opportunity to acquire some treasure as well.
It was fantastic to see some 16 sellers on site today, having on offer a huge variety of wares including a variety of vintage/classic radios, some more modern radios (there was an IC-7300 and flex SDR gear on offer), along with a variety of accessories such as components, power supplies, microphones and more. The only thing missing were buyers, with sellers trading between themselves for some part. Some real bargains were missed out on!
The BBQ was a huge success, selling out of all the meat on offer and also raising funds for the Association.
It was clear that based on the activity today that Radio and Electronics Car boot sales may have to become a more regular event to encourage more people to come along.
On Wednesday evening, ABC Radio Hobart contacted us through our Facebook page wanting to know if someone would like to talk about the experimenters night and what happens at REAST.
Justin VK7TW made a detour from his regular sojourn to the club rooms to visit the ABC studios and give an interview on the things that have been happening recently on Joel Rheinberger’s Evening’s show.
With permission from ABC, we can share the audio of the interview below.
On Wednesday, REAST repeater officer Damien Styles VK7SD commissioned the new Yaesu DR-1X digital repeater much to the excitement of the gathering of people at the Wednesday evening experimenters group. While the repeater was purchased some time ago, it has only been in the last couple of weeks that frequencies have been allocated by the ACMA for it’s usage.
The Yaesu DR-1X is capable of both analogue and C4FM digital voice and automatically switching between the two modes. Soon an additional module will be acquired to provide DMR, DSTAR and p25 digital voice capabilities.
This repeater is on air right now, with an output frequency 438.675Mhz with a 7Mhz negative offset for the input on 431.675Mhz.
Our repeater officer would be most interested to hear signal reports from you. If you are able to access the repeater, please let Damian know by emailing [email protected]!
The REAST Club Buy of the Radioddity GD-77 DMR handhelds has been a great success, with a total of 20 handhelds sold in this club buy.
We’ll be taking a break for a bit to focus on other club activities, but there may be another buy depending on developing interest.
A big thanks to Clayton Reading – our DMR Guru – for all of his hard work in the setup and distribution of radios to everyone, and of course thanks to everyone for buying in and opening up a new aspect of this exciting hobby
Great News ! The frequency assignment to get another 70cm pair for adding a digital repeater to VK7RAD has been completed, and ACMA has provided the allocation we need to progress with the installation of the Yaesu DR-1X repeater. Further news coming as things unfold, so stay tuned !
This monthly presentation covers aspects of Radio Astronomy ranging from the development of Radio Astronomy (Karl Jansky and Groth Reber) through to the role of microwave mapping in developing theories of the universe and studies into HF planetary radio emissions from Jupiter.
