The AnyTone AT-D868UV is a staple for DMR (Digital Mobile Radio) users in the UK, largely due to its versatility and the availability of pre-configured "codeplugs"—the configuration files that tell the radio which frequencies, talk groups, and zones to use. The Core Components of a UK Codeplug

To build an effective UK codeplug, you need to understand the networks available:

: Provides dedicated codeplugs and CSV files specifically for the 868 and 878 models. This is excellent if you primarily use the FreeDMR network. Anytone.org

  1. UK General (Analogue): 2m (144-146 MHz) and 70cm (430-440 MHz) bands for FM voice.
  2. UK Simple Light (Analogue): 446 MHz licence-free channels (often stored for monitoring or emergency backup).
  3. DMR (Digital Mobile Radio): The digital side, including the UK wide-area repeaters (UK Echolink Network, Phoenix, GB7, etc.) and the dynamic BrandMeister talkgroups.

A codeplug is a configuration file that contains essential information such as frequencies, tone settings, and other parameters that define how a two-way radio operates. It acts as a digital key that unlocks the full potential of the radio, enabling users to access specific channels, set privacy tones, and utilize advanced features.

Analogue Integration: The Often-Overlooked Half

Despite the digital trend, VHF/UHF analogue remains vital in the UK for simplex, legacy repeaters, and emergency backup. A solid codeplug dedicates equal care to analogue channels. The UK band plan dictates that 144.000–146.000 MHz is for exclusive amateur use; thus, the simplex calling channel on 2m is 145.500 MHz (FM), and on 70cm it is 433.500 MHz. These should be in every codeplug’s top zone.
