OPENGD77 – Cheatsheet
1. Scanning. Scanlists can still be entered, but are now ignored. When you press SCAN (orange button
twice) the OpenGD77 will scan all the channels in the current ZONE and ignore scanlist settings.
2. The Channels can still be allocated a Contact(used as a Talkgroup) but this setting is now ignored.
Channels remain defined by CC, frequencies and TimeSlot – and receive ALL talkgroups on that slot.
3. You can enter any talkgroup (not in the TGList) from the keypad prefixed with # and followed by
[GREEN]. You can enter an individual Contact number prefixing with ## and followed by [GREEN]
4. When entering Talkgroups into the Contact list, you have the OPTION of choosing a Slot. This has
the effect, that when the channel is switched to that TG, the channel slot setting is ignored and replaced
by the slot setting in the contact.
5. The option to program keys to different functions remains, but is ignored. The [BLUE] key is also
referred to as the [FUNCTION] key. The [GREEN] key as the [MENU] key. The [ORANGE] key as
the [QUICK MENU] key.
6. You cannot directly edit memory channels. Instead you use the [ORANGE] quick menu to copy the
channel to VFO. Edit the VFO. Then switch back to the target memory channel and use [ORANGE] to
copy the VFO to that memory. Cannot create new memory channels – but you can fully edit old ones.
7. The Zone can be changed by pressing the [GREEN] menu key twice. The list of Zones includes a
permanent one called ALL CHANNELS which when selected puts all the channels into one big Zone.
8. Key combinations:
[BLUE] + left - reduces the power output in multiple steps
[BLUE] + right -increases the power output similarly
[BLUE] + * toggles FMN with DMR
[ORANGE] twice starts scanning contents of selected Zone (individual channels can be set to be
ignored by scan)
[GREEN] stops the scan
[RED] toggles Memory/VFO mode
In VFO mode with the > pointing to R(x) the UP/DOWN keys change both TX and RX frequencies
together
In VFO mode [BLUE]+UP/DOWN changed the > between R(x) and T(x)
In VFO mode with the > pointing to T(x) the UP/DOWN keys only change the TX frequencies (split)
# number [GREEN] enters a group call contact/talkgroup
## number [GREEN] enters and individual call contact/talkgroup ( eg 9990 echo on phoenix)
### opens the Contact list for scrolling.
