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.

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"), 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. The MD-380 Tools web site is a good place to start: MD380 Tools
A separate branch (Toolz with a z instead of an s) that has a simple to use Windows program to "flash" the fimrware to the radio and then upload the user database can be downloaded from KG5RKI TyMD380 Toolz The site also includes details of the new features and a video about the tools and how to install them. NOTE: the KG5RKI web site was hacked and "off the air" for much of June and July of 2018 but has been recreated again to the benefit of the amateur radio community!
KD4Z has created a Virtual Machine environment under Windows for flashing the Tools firmware and updating the user database. He has provided an excellent guide. See the MD-380 Tools site above. For users who want something simpler, PD1LOI has modified the KG5RKI FlashTool to work with the Tools (with an s, not a z) firmware. The Zipped package can be downloaded from the CCC web site MD380-390 FlashTool There is a Facebook Support Group for the KD4Z Toolkit KD4Z Toolkit Support Group

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.
