VK7MO 10GHz Grid Square EME Adventures Presentation

Wow, Rex Moncur VK7MO gave us a four part illustrated presentation on his 18,000km journey on his recent 10GHz Grid Square chasing EME DxPedition. Rex traveled far and wide into VK3, VK5, VK6 and VK8.

Rex started with a short presentation on the VK6 Northern Corridor Radio Group as he was very impressed with this club and the things they get up to. Rex then moved to a tutorial on EME propagation and then moved to his grid tour and get OK1KIR up to over 100 grid squares on 10GHz EME. These grid squares were from the OH, OG and OF grid fields. There were a few interesting and frustrating things that happened along the way but Rex achieved his goal!

REAST Secretary Scott VK7LXX signs sublease with Barry McCann of TMR

Earlier this week members of the REAST Management Committee met with a representative from Tasmanian Maritime radio to sign a long term lease, securing access to the building for ten years, with an additional ten year option.

The signing of the lease ensures that members will be able to enjoy the clubrooms that have been the home of the WIA Tasmanian Division and then REAST for over 25 years.

Particular thanks goes to Barry McCann who has been instrumental in negotiating and securing the lease with the Hobart City Council and ensuring that the interests of REAST members were maintained.

Remote Control Aircraft Presentation Fills Clubrooms for June Presentation Night

Ron Cullen presents on RC Aircraft Controls

Ron Cullen presents on RC Aircraft Controls

Wow standing room only for our REAST member Ron Cullen’s presentation on some very impressive radio control kit.

Ron started with some history of his Radio Control (RC) journey starting in 1979 when he was in the Air Force and they had an Aero modelling club and even showed and RC controller from that era.

Ron was posted all over Australia and he took his RC planes with him. Zoom to 1998 and Ron left the Air Force and shelved his interest in RC. A couple of years ago he started to get back into it. The night Walrus was his first purchase and some VR google was he first foray back into RC. This included some interesting innovations including a Visual Approach Slope Indicator for his RC planes and this mirrors the use of this technology at commercial runways.

Richard VK7ZBX’s impressive 1.8m mobile dish.

We had a great roll up to our forum with many people coming along with show and tell.

Notable there was a large 1.8m AZ/EL dish that was trailer mounted that Richard VK7ZBX brought along – more on that later.

The night was all about sharing people’s experiences. We started with Rex VK7MO who took us on a picture journey of his adventures in dish mounts starting with 1296 and working through each iteration of the mounts and heading into the 10 & 24GHz telescope mounts with milling machine table used for accurate azimuth adjustment. Rex’s show and tell included the azimuth and elevation measuring devices. Thanks Rex.

REAST AGM and 2017 Committee

Last Sunday REAST held it’s AGM. A modest number of members attended and reports from President, Secretary and Treasurer followed by reports from Ex-Officio officers. Members heard that the Association is currently started a path of change with an increase in activities and further changes will occur this year as a result of the changing lease arrangements and introduction of NBN at the clubrooms. The financials for the Association were in good shape, with a loss for the year attributed to the purchase of new assets.

A committee was elected, with the only change from last year being Scott VK7LXX appointed as secretary as Sean VK7FAZE has stepped down for the year to focus on other projects. Congratulations to all members of the incoming committee. The REAST Committee for 2017 is:

President:            Ben Short VK7BEN
Vice-President:       Justin Giles-Clark VK7TW

Treasurer:            Alan Jeffrey VK7KAJ
Committee Members:    Larry Hower VK7WLH

Draft Minutes for the AGM & reports will be placed on the members only section of the website shortly.

From Maxwell to Marconi – A History of Electrical Radio

February Presentation by Mike VK7MJ

February Presentation by Mike VK7MJ

Last week REAST held it’s first major presentation for the year with Mike Groth VK7MJ taking the audience through a history of radio from Maxwell up until the time of Marconi, where signals were largely generated in the form of electrical spark and modulation of the spark. This was the time of spark gap transmitters and who knew it would be so interesting!

Mike presentation took us through how a spark transmitter was tuned, how a coherer, magnetic, electrolytic and crystal detectors worked, and the role wireless played in the sinking of the Titanic in 1912. We learnt about the early attempts at wireless telephony, the development of the HF alternator and the infamous Pousen Arc converter, and Fessenden’s pioneering Christmas broadcast of 1905.

For those who missed the presentation, we will soon have it up on our Youtube Channel, so watch out for that!

NBN to Improve Member Services

Contractors installing conduit

For those visiting the REAST Clubrooms in the last couple of weeks, you may have noticed that there have  been some rather significant trenches being dug outside and down the hill. This has been to install the conduit for the National Broadband Network (NBN) Fibre.

There have been quite a few difficulties in being able to install the NBN to the REAST clubrooms given the location on top of the Queens Domain – The eventual solution has been an aerial installation of the fibre along  powerlines that come near to the clubrooms before completing the distance with underground conduit – no small feat considering that after about 2 feet you hit solid dolomite rock!

The NBN will allow us to provide many new and exciting services to members via the internet, mainly through the much improved network speeds that will enable the ability to use many of the online streaming services to provide live streams. The REAST Committee also have a few other tricks up their sleeve so be sure to watch this space!

 

Saying Adieu to DATV Studio

Last Wednesday evening a small group of members gathered at the REAST club rooms to disassemble the DATV studio, in preparation for the rear shed being redeveloped by Tasmanian Maritime Radio (TMR) to move their operations hub into.

Amateur Television has played a large part of REAST, with the first broadcasts occurring from VK7OTC in 2005, in a makeshift studio, before moving to it’s own studio in 2010. Broadcasts started out as analogue before moving to DVB-S then DVB-T transmissions.

Digital Amateur Television broadcasts are planned to make a return in 2017 with the studio relocating into space currently used by TMR after they move to the redeveloped rear building. It will be an exciting time with the opportunity to rebuild the studio.

REAST club rooms will continue to open on Wednesday evening with other activities including satellite communications, software defined radio and homebrewing, along with all the regular show-and-tell and discussions you know and love!
