REAST Virtual Club Gathering – DSTAR

The REAST club virtual gathering for June 2020 focused on Digital Smart Technology over Amateur Radio or DSTAR thanks to Clayton VK7ZCR and Scott VK7HSE.

Clayton and Scott covered a short history and we learnt that DSTAR is an ICOM proprietary system using the AMBI chip set that predates DMR.

If DSTAR users wish to use gateways then a user is required to register using the ICOM registration system, this enables a user to talk through repeaters and gateways.

There are four DSTAR repeaters around VK7 – VK7RCR, VK7RAD, VK7RRR and VK7RJG and access to all repeaters and gateways are available via these repeaters.

Scott covered DPRS which is the DSTAR equivalent of APRS or Automatic Position Reporting Service – most DSTAR radios have GPS within them and can automatically report position at a user defined interval.

The DSTAR equipment available is mainly ICOM equipment including: ID1, IC2200H(with DSTAR option), ID51, IC9700, IC7100, IC5100, IC4100 and Kenwood D74. All these transceivers will work with VK7RCR out of the box and they can be updated to include all the other DSTAR repeaters.

Some of the traps were – the GPS beaconing regularly and wiping out the voice channel and changing to CQ mode and the repeater telling you the repeater information every time following a transmission.

There were some great questions from the audience and a huge thank you to Clayton and Scott for the presentation.

REAST Virtual Club Gathering – DMR

VK7HSE on DMR
 
Our second whole of club virtual gathering was a focus on Digital Mobile Radio with Scott VK7HSE.
 
Scott focused on the Radioddity GD77 handheld which is very popular in Southern Tasmania. Scott started with a short recap on DMR terminology then dived into exploring Roger Clarke’s OpenGD77 firmware and the features of this firmware enhancement.
 
This firmware update sits on top of the normal GD77 Firmware and provides many more features and the ability to download the user database for your area which then presents the callers callsign instead of their DMR identity number.
 
Scott took the audience through where to get the firmware update from GITHUB and then how to load the firmware on your GD77. Some of the features of the loading software were also covered.
Scott and Clayton VK7ZCR then took questions from DMR, FM and Chat channels. A huge thank you to Scott and Clayton.
