Australian DMR Repeaters

There are several DMR networks around the world, and more and more start all the time. The Australian DMR network currently covers the entire country and is for Australian residents only.

It can often be hard to find which DMR repeaters are online, offline and where they are, especially if you travel a bit like me.

Here is a few links that may be of some use. Please let me know if these links no longer work.

A map of all DMR repeaters around Australia is available here.

If you want to check the status of these above repeaters, have a look at this page. It shows which ones are currently online, or offline.

Online repeater map is a great page showing all repeaters around Australia. It is well worth the look at if you are traveling or are going to be in Australia. https://www.onlinerepeatermap.com/

Another way is via the DMR database. If you put the start of the repeater call sign in the middle repeater section it will list the repeaters in your area. For example, all repeaters in my area start with VK3, so I put in VK3 in the middle callsign box and selected begins with and got a list of registered repeaters. This will work all over the world. https://www.radioid.net/database/search#!

Ham Radio History

Welcome to the site

Hi there from Down Under, Melbourne Australia. Thank you for visiting my radio web site. Below is what items by category is available on this web site.

Thanks again for visiting. This web site is still being built, so don’t forget to Follow us to get updates as they come. You can do this by the Follow Us box.

I also have a travel web site, so if you are interested in Australia at all, I highly recommend you visit it. One of our biggest trips was a 5 week holiday through outback Australia. We traveled through outback Australia to see why these remote locations are there, how they started, and what are they doing today. These locations are some of the most remote places in the world. This trip has an amazing amount of Australia’s information, pictures, maps and video’s and I guarantee you will learn something even if you are an Australian or been there before. See the Northern Australia trip via the link below. https://sangsteradventures.wordpress.com/

Hope to hear you on the air sometime soon!

Power without Power

In 2019 my family and I went on a five week trip through outback Australia to some of the remotest parts. We had no access to power, reception, food or water for days. We took what we had.

Here is a cheap way to have power without having power, a rather inexpensive way to do it. I took this short video in outback Northern Territory in the top end of Australia.

Chirp

CHIRP is a free, open-source tool for programming your amateur radio. It supports a large number of manufacturers and models, as well as provides a way to interface with multiple data sources and formats.

Supported Radios

Supported radios can be found on their web site at https://chirp.danplanet.com/projects/chirp/wiki/Home. This list is updated as the software is updated.

Download Chirp

Chirp can be downloaded from the following web site. Should things stop to work or connect to outside web sites, it probably is because you don’t have the latest version. You do NOT need to uninstall an existing version of CHIRP before installing a newer one. Just install the new one and it will replace the existing copy. If you already have an old copy on your PC, make sure you close it first, otherwise you will get an error while installing.

https://trac.chirp.danplanet.com/chirp_daily/LATEST/

Update Chirp

On opening Chirp, it will tell you if an update is available. Simply click on the link, download the latest version that is appropriate to your platform, and then once the file has downloaded, run the file. It will update your software. No need to un-install the old one, and it seems all the settings, such as file locations, stay in the new version.

Known Issues

Chirp list all their known issues online which is great. You can see the current list here:

Download from Radio

I think the first step is to first download what is currently on the radio. This will give you a starting point which can be saved should your upload not work. At the very least doing this will allow you to check communication between your PC and radio works, and you will have a file that you can look at to see how it was programmed.

To do this, go to the Radio menu and click on Download from Radio or Ctrl-D. This will give you a small dialog box where you can select the Com Port, radio and model. Your model of radio may not exactly be on the list, so you may need to do some work to see which one to select as an alternative. For example, I have a Baofeng GT-3TP, but it is not on the list, so I have to select the BF-F8HP model.

You can then either edit what you have and then upload it back to the radio, or start from scratch. If you want to start from scratch, you may want to see what Query Data sources are available first.

If you have trouble connecting your computer to your radio, then first make sure it is connected correctly and all the way into the radio. If this doesn’t fix it, go to Windows Device Manager then right click and select properties. If error code 43 comes up, then right click on it and uninstall. Then from the Action menu, scan for updated devices.

Query Data Source

Chirp can can sync your radio with the repeaters listed on several different sites. This will save you a lot of time getting the latest frequencies, offsets, and tone squelches etc. These sites can be found on the Radio menu, Query Data Source, then you can see a list of them.

I usually use the RepeaterBook option and then from this you can select political or proximity depending on what you want to do. If you select proximity it will put the repeaters in distance and band order, not frequency, however you can change this prior to uploading to your radio.

For me, once I have selected proximity, I sort the list in order of frequency, however this doesn’t change their location channel.

Then select the Frequencies you don’t want in your radio, for example, the ones on bands your radio does not use. Right click and select delete, and move all memories up. You may need to sort again in order of frequency; however, this doesn’t change their location channel.

I then export the tab to a csv file.

I then open the CSV file in Excel and sort in the order I want, frequency. Be sure to re-number the location numbers once in the correct order. MAKE SURE COLUMN K = FM. Make sure you remove any comments in column O & R. You can also add any additional frequencies you want to.

Open the CSV exported file, now you will see the locations are in order of Frequency as set above. You can still make any changes required and save or save as which will update the CSV file.

I will add notes here on how to program your radio soon.

My Radio Diddity GD-77

Starting in digital can be a little overwhelming to start with, no matter how many years you have had your licence. I even had a digital scanner for many years prior to starting in the digital world of Amateur Radio.

After working out what digital radio is, what you can do on it and how it worked, I then started researching what equipment was required.

According to other reviews at the time I was looking, many people claimed that the RadioDitty GD-77 was the best value for money.

My Radioditty GD-77 while on holidays
My Radioditty GD-77 while on holidays

After a month or so of using the RadioDitty GD-77 through repeaters, I purchased an OpenSpot2. I did a lot of research prior to this, and had settled on the OpenSpot1, however when I went to purchase it, only the OpenSpot2 details. It happened to be the week it was launched, so there were no reviews available at the time.

Currently my digital setup is very simple, it just has:

  • One hand held radio, the Radio Ditty GD-77, this came with charger, USB cable and remote microphone
  • OpenSpot2 Hotspot. This came with a power cable.

With this simple setup I am able to talk the world via

  • The BrandMeister network
  • The Australian VK-DMR network
  • Other DMR networks around the world, eg New Zealand, Canada etc
  • YSF Reflectors
  • C4FM
  • NXDN Reflectors
  • SharkRF servers

The above is just to name a few networks. Each of the above networks range from a few Talk Groups, to thousands upon thousands of them from all over the world.

In 2019, my family went for a huge five week trip through outback Australia. We went to some of the most remote parts of the world. We had to carry a lot of water, food and supplies. We also had to carry extra battery power to charge fridges etc. I would have liked to have taken a HF radio with us given the outback probably didn’t have a lot of interference, however we simply didn’t have enough room, or power.

Instead we took a very simple setup, my GD-77, my openspot2 and a small battery back that ran my openspot and mobile phone. Even without power, I was able to talk the world with a little mobile reception or wifi.

Many people have many radio’s for different networks, making it hard to keep updated, and obviously cost a lot. My digital setup costed far less than it costed me to get on 2m/70cm many years ago. And did I mention, this radio also does analogue, so yes, you can use this radio on 2m and 70cm simplex or via the repeaters and no one will know you are actually talking on a digital radio.

The only down site is it is a little hard to program and navigate the channels. The radio is built for commercial operations, and not really for amateur radio, however it can be done. Commercial operations usually have a small number of talk groups or repeaters/frequencies, where as amateur radio uses a lot. However once you nut it out, it isn’t really that hard.
