Poniżej zalecane / uwagi ustawienia do pracy w DMR rekomendowane przez innych (wynikające z doświadczeń, patrz na końcu opisu źródła informacji):
np w GD-77 w CPS "General setting":
W ustawieniach kanałów:
Kiedy nasz zasięg do przemiennika jest taki że nie zawsze wchodzimy na niego możemy ustawić w GD-77 parametry które pomogą nam w tej sytuacji, np. zwiększenie liczby prób dostępu do przemiennika z 1 do 3. W programie CPS dla GD-77 szukamy ustawień dla "Signalig system" i ustawić następujące opcje jak niżej (zalecenia Roger'a VK3KYY):
Uwaga dla użytkowników GD-77 z firmware 3.1.8:
Tom Britton: still broke in firmware 3.1.8. ALSO PLEASE fix Admit Criteria of Color code free! It is a pain to wait for the carrier to go off! Known GD-77 bug list The following is a list of known bugs that are present in the GD-77 firmware V3.1.8. Radioddity are aware of these issues, and have promised to work on them: 1) DMR talk permit tone (General Settings > Talk Permit Tone) In DMR digital mode, DMR talk permit tone always sounds, even if out of range of DMR radio repeater, or the repeater is busy, or the radio is denied. The talk permit tone should only sound once access to the repeater is confirmed. NB: until this feature is working properly, Radioddity have inhibited the DMR talk permit for repeater operation no matter what your CPS setting is 2) Issue with the Admit Criteria (part of each digital channel settings). Using Colour Code Free, when the channel is not in use, the radio is allowed to TX (good) When the opposite timeslot is in use, the radio is allowed to TX (good) When the selected timeslot is in use for another talkgroup, the radio is NOT allowed to TX (good) HOWEVER, when the selected timeslot is in use for the SELECTED talkgroup, the radio is still NOT allowed to TX after the transmission has ended, until the RF carrier on the frequency has dropped (bad - user is unable to reply to a transmission in their talkgroup) Źródło: https://www.facebook.com/groups/789727154519141/
