This notice went out today (12/26/22) on the Group IO email.


It's with a great sense of loss that we announce that Roland Kraatz W9HPX is a silent key.  He was a wonderful person who always seemed to have a smile.  He was a prime mover in the Charlotte Digital Radio Group and supported all of our area radio clubs with presentations and digital radio assistance.  He loved educating people about digital voice radios and helping more hams become active in the digital modes.  Arrangements have not been announced.

Roland will be greatly missed, as a friend, a fine amateur radio operator, and as a technical advisor to many. Join in as we honor Roland's memory, pray for his family, especially his wife Gloria


This may temporarily impact some things such as dontations and operation of the Carolina Link, but plans are underway to make these impacts as short as possible. Please be patient as we mourn and try to sort out the pieces necessary to keep things running.

We are a group of amateur radio (ham radio) enthusiasts who encourage the development and popularization of VHF and UHF digital voice modes in the Charlotte metropolitan area.  No membership application required!  Join us on one of our repeaters, via a hotspot or dongle, by joining our Charlotte Digital Radio Group (CharlotteDigitalRadio) or coming to our monthly dinner meetings.


We operate multiple D-STAR repeaters, three DMR repeaters, two System Fusion repeaters with Wires-X one NexEdge repeater, as well as a new MMDVM Multi-Mode repeater which operates D-Star, DMR (Brandmeister), Fusion, and P25.  We also operate an FM analog repeater (220 band) and a GMRS repeater.  Internet connections at each of our sites allows us to inter-link repeaters to provide wider geographic coverage.  

Our repeaters are open.  We don't restrict use to "members" only.  We encourage all licensed hams to use our machines.  This is our gift to the ham community.  

We also try to educate and inform hams about the various digital voice modes.  This web site, our CharlotteDigitalRadioGroup, and on the air help are all parts of that effort.  We welcome newcomers to join us, get to know us and become involved in this great endeavor.  We think digital voice modes are fun.


Our repeaters are open and we want you to use them, but they are not free. It costs money, lots of money, to keep multiple repeaters at multiple sites on the air. We built and support these systems through equipment donations, volunteer labor and financial contributions from a large number of ham radio operators. A repeater installation can cost several thousand dollars. We try to carefully manage our expenditures, but when equipment breaks it must be repaired or replaced, sometimes at significant cost. For example, a failed antenna could cost several thousand dollars to replace if we must hire a tower climber. Our sites all have internet service and one site is rented. Just those ongoing bills exceed $2,000 annually. If you like using our repeaters please consider making an annual donation. We suggest $50 per year, but any amount you can donate will be greatly appreciated. Use the Donate button below. Whatever you can give, we THANK YOU!



    Jump on our repeaters anytime. In order to stimulate interest, we currently link our repeaters to the following nets:

A note about linking and unlinking the repeaters to reflectors (examples for are D-Star, but applies to others as well):

  • Feel free to unlink the repeater as needed (not during an active net or other conversation)
  • Identify yourself (verbally) and state your intent
  • Unlink the repeater (send the letter 'U" in the the 8th position of the call sign field)
  • Link the repeater to the desired reflector (send REF054CL in the call sign field, for example)
  • Conduct your business on the newly linked reflector
  • MOST IMPORTANT: When you are finished, please unlink the repeater. If it was previously linked, please restore the previous link
  • Remember - you are not the only person using the repeater, so leave things like they were and ID yourself as you begin and end.
