The Central Ohio Digital Interconnect Group is a group of dedicated amateur radio enthusiasts who want to further digital modes of communication in the Central Ohio area. We have been active in packet, APRS, VOIP and have pioneered new technologies such as D-Star digital voice and data connectivity, APCO P25 and Mototrbo DMR.

NOTICE: July 2015

We will be making significant changes to the layout of TalkGroups and Time Slots on our DMR Mototrbo repeaters in the near future. We hope to have sample codeplug templates available for download from this website within the next two weeks. The changes will take effect on Thursday, July 30th. To help with this transition, we will be attending the Columbus Hamfest on Saturday, August 1st in the morning at the Aladdin Temple (3850 Steltzer Road). You are welcome to bring your radio and we will be happy to help program the new TalkGroups for you at the show. This is a great local gathering and also hosts the ARRL Great Lakes Convention. Admission is only $5.00. Come Join us!
