A talkgroup is a numbered group destination for digital calls. A DMR channel typically selects it as a digital group contact.

DMR TDMA divides a 12.5 kHz radio channel into two time slots. A suitably operated repeater can provide two separate call paths.

Guided checks for reception problems, silent DMR and high SWR.

The AE125H does not decode digital voice formats such as DMR or D-STAR.

Automatic detection of DMR, NXDN, dPMR, P25 Phase 1, D-STAR, C4FM, Alinco EJ47U and D-CR.

The software is not a scanner decoder upgrade: DMR, NXDN, dPMR and ProVoice require the appropriate activation on the radio.

Final exercise: a purely fictional DMR access point specifies CC 3, TS 2 and TG 9 as a group call.

D-STAR DMR Hotspot

D-STAR and DMR are different systems, so tuning two radios to the same frequency does not make them compatible.

An FM demodulator does not turn DMR or D-STAR into ordinary intelligible speech.

The Pi-Star guide treats the radio channel separately from connection to the chosen DMR network.

Pi-Star supports multiple digital modes and networks, including D-STAR, DMR, YSF, P25 and NXDN.
