P25 Emergency Services Network Build

September Presentation Night

The first Wednesday night of September it was standing room only in the REAST COVID-Safe clubrooms for a presentation on how to build a statewide P25 based Emergency Services radio network given by Andrew Johns VK7AJ.

Andrew covered all aspects of a P25 Network and its use within a dispatching organisation like Police, Fire and Ambulance. The topics covered included – What is it, its benefits, comparison with its competition – TETRA, services and trunking.

Andrew then went on to architecture, interfaces, voice & data calls, encryption, the future and then took a look at the local environment.

A huge thank you to Andrew Johns and the respective organisations for the presentation.

REAST Returns to the Clubrooms

Members were greeted to a friendly message on the whiteboard thanks to Paul VK7FPCL – our wonderful Clubroom’s Officer who has been ensuring that everything is wiped down between meetings and keeping us COVID -safe with supplies. A huge thank you to Paul.

Last Wednesday night was a joint welcome back to the club rooms and Presentation Night on the ICOM IC9700 Experiences and Learnings. We had about 20 people along to the presentation in person and had over 20 on the streaming channel. It was a group effort with input from Rex VK7MO, Richard VK7ZBX, Hayden VK7HH, Alan VK7KAJ and Larry VK7WLH all of whom have IC-9700s. 

A video of the presentation is available to the REAST Youtube channel – https://youtu.be/nYM5kgTF4SA.

Rex started with an outline of the IC-9700 functionality and comparison with the IC-910H. This led to whether you could effectively operate the rig out of the box. Some impressions where shared, the question of frequency stability was explored and the various GPS Locking options were explored with Rex, Alan and Hayden. Then Rex continued with 23cm operation, Digital/EME operation and Linear/Transverter operation.

Richard then took the audience through a comprehensive outline of using the IC-9700 for satellite operation including a recording taken of a contact with VK4MIR.

The presentation then moved to key configuration items that can be/need to be tweaked to improve including – Rex outlined the HM-36 Mic Mod and Hayden did a promo for his digital modes setup and firmware update videos.

Hayden then took the audience through the Remote Operating Software from ICOM – RA-BA1.

Larry finished up with a description of the WIN4ICOM software which also has remote control capability.

We then took questions from the audience and stream and retired to enjoy the clubrooms again!

Thanks to Rex VK7MO, Hayden VK7HH, Alan VK7KAJ, Richard VK7ZBX and Larry VK7WLH.

A great return to the clubrooms.

REAST Clubrooms Closed – COVID-19

Given the recent advice from the Australian Government and Health Authorities about indoor events need 4 square metres per person, the committee has taken the regretful step of closing the clubrooms until further notice.

This affects the Wednesday afternoon group and the DATV Experimenter’s Night.

As things develop we will keep members in the loop through regular email and broadcast updates.

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.

Everybody Loves Wednesday Nights @ The Club Rooms!

Don’t think that because the Amateur TV experimenters group is having a break while waiting for a new studio to become available that things on a Wednesday night have slowed down. This past Wednesday saw a cracking display of activity at the club rooms.

Every Wednesday evening the REAST clubrooms are open for members to attend, being up their projects to work on, or just sit down and have a bit of chat about the week with friends.

Tom VK7NTK was busy tuning an analogue filter to boost frequencies in the 1000Hz – 1500Hz range. It is hoped that this board will help improve the attenuation issues being seen with the raspberry pi based IRLP node that is a whole tale in itself!

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!
