Update 1/16/2023: Some newer DMR radios have built in APRS capability. SCHEART and NCPRN DMR networks do not support APRS data. Operators must ensure they do not transmit APRS beacons on the networks since this transmission mode is NOT AUTHORIZED. Thanks for everyone’s support.
Creating a code plug can be very time consuming and for a new user somewhat confusing. Initially the Sumter Amateur Radio Association and George Mudd, KK4F, created sample code plugs for SCHEART system covering all varieties of DMR radios. Operators could download the base code plug and modify it to quickly get on the air. However, with the growth in DMR manufacturers and a wide selection of radio models, it has become impossible for a couple of volunteers to keep this list current.
If you have a radio code plug not listed below and would like to have it posted for others to use, please email it to George at kk4f@arrl.net. Be sure to provide the Manufacturer’s name and radio model number.
If you find an error in these base code plugs, please email the error to George at kk4f@arrl.net.
SCHEART would like to express special thanks to KK4F, the Sumter Amateur Radio Association and to every operator who contributes to this collection of base plugs for the SCHEART and PRN system
