VE6RYC is the first DMR repeater in Calgary and it is proving to be a very interesting addition to the amateur radio scene in Calgary. Thanks to CARA for getting it on the air! The information below is provided to help people get started with the world of amateur radio DMR.

Check it out if you have access to any of those digital networks through a repeater or hotspot.

  • TGIF Network Started in 2018, TGIF's goal is to be less formal than other DMR networks. It is already supported in Pi-Star hotspots and by both versions of the SharkRF Openspot.

The Tytera MD-380 DMR UHF radio has become popular as an entry level DMR radio with hams around the world. Several CCC members have these radios already. The codeplug below includes configuration for the DMR Repeaters in Calgary and Edmonton.

The MD-380 has multiple Zones with up to 16 Channels in each Zone. The Calgary codeplug above has 4 Zones: Calgary, Test, Edmonton, and Simplex.
The channels provide access to the local DMR repeater and to its various Talkgroups, as well as to 2 local Calgary FM repeaters (VE6EHX and VE6OIL).
The Talkgroups include Canada, North America, and World Wide. These Talkgroups are always linked. There are several other Talkgroups that are linked only when activated by a user. User activated links include TAC310 (a sort of "chat room"), Quadnet Array, UAE1 and UAE2 (which are English language world wide "chat rooms"), and several provincial Talkgroups (AB, BC, MB, ON, QC, and NB).

Enhanced Firmware for the MD-380

There are a lot of clever hams in the world! Some of them, in particular Travis Goodspeed, have turned their attention to the MD-380 DMR radio. The capabilities of the MD-380 have been greatly expanded through their efforts to create "experimental" firmware. There are several branches of firmware available.
One branch is supported by KG5RKI under TyMD380Toolz, with software and documentation.
KD4Z has created a Virtual Machine environment under Windows for flashing the Tools (with an s, not a z) firmware and updating the user database. He has provided an excellent guide. It requires some computer skills. See MD380 Tools for all the details.
For users who want something simpler, PD1LOI has modified the KG5RKI FlashTool to work with the Tools firmware. The Zipped package can be downloaded from the CCC web site MD380-390 FlashTool NOTE: version 2.00 has been released. The older versions no longer work.
There is a Facebook Support Group for the KD4Z Toolkit KD4Z Toolkit Support Group
There is also software available that can create and modify a codeplug, flash the Tools firmware, and program the user database. EditCP by Dale Farnsworth. This software included several enhanced features that are not available in the standard CPS, including drag and drop reordering of entries!

Radioddity GD-77 dual band (2m/70cm) DMR/FM analog handheld is now available for around $100CDN, including programming cable. Not as feature rich as the MD-380 with Tools, but still a good option for someone who wants to have both bands in a single radio. It does have the option to monitor 2 frequencies (called dual watch), so you can monitor your favourite 2m analog repeater and your favorite UHF DMR repeater. The 3.0.6 and newer firmware has space for up to 10000 contacts. It also has promiscuous mode (called "monitor" in the GD-77) that will decode any signals on the selected timeslot, just like the MD-380. Note that firmware revisions usually come with customized programming software, which may require rebuilding the codeplug from the earlier firmware, at least for the DMR settings. The older codeplug likely won't work with the new firmware until it has been rebuilt. Firmware and software updates are available on the Radioddity web site: Downloads There is a fairly active Facebook Group for the GD-77 radio.
