Frequency Asignments

Note 1. The Wide Band 147.925 Mhz, Offest -5 MHz repeater operates in reverse to that desiginated in the licence. That is transmitting on 147.925 MHz and receiving on 147.325 Mhz to avoid claimed interference from nearby telecommunications transmitters and or pagers. This has been in place for many years and was setup this way when I joined the club in 2020.

Note 2. Contrary to the listing in the table the 438.725/431.725 MHz pair host the digital services (DMR and P25 at present) and the 439.950/434.950 MHz pair host the FM Analoue repeater.

AllStarLink Node 54032

I have commissioned a AllStarLink Node on the VHF repeater at the Roachdale Scout Group VK4BA clubhouse and radio room. This is an ICOM FR5000 147.925 MHz, with an offset of -600 KHz, and a CTCSS tone of 91.5 Hz, operating at medium power.

The project was operational on the UHF FR6000 for some time, however, it is now operation on the VHF FR5000 repeater, and linked to the VK3RBA Victorian Link Network.

The AllStarLink module is build by VK4PK with an RPi and a Repeater Builder (N3XCC) USB-RIM Lite (2016), Repeater Builder RB RIM Lite.html

This AllStarLink Node is now suspended pending a committee decision regarding continue funding the project.

My attempt at a new mordernistic logo for the Brisbane Amateur Radio Club

To explain; the black lines show the club's geographic reach. This is the area we represent/service the best. An ambitious paddock from the main range to the far left and to Moreton bay to the right. The red circle is the centre of our communication radiating out to the world. The Brisbane river runs through the middle into the Bay. On the left is Mt Coot-tha with the TV towers (A bit figurative but convey a message for radio waves. Mt Cotton is on the right with a single tower. You get the idea. In the end the club decided to go for a more traditional style for their logo. I make no claims to being an artist.
