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.

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.
