After using the new GD-77 firmware for a few days, I’ve noticed that there appears to be a new bug associated with the DMR ID / Contact display.
When transmitting to a repeater, after I release the PTT, the incoming ID is shown on the screen, which is my DMR ID – this is normal – but in firmware 3.1.8 the DMR ID does not get removed from the screen after the transmission from the repeater ceases, a few seconds after the PTT is released.
Looking carefully at what happens, it seems that the DMR ID is not always displayed, on either 3.1.8 or previous versions e.g. 3.1.6, when transmitting to a repeater, but it seems that if you transmit for more than a few seconds, then release the PTT, the DMR ID is normally displayed.
In firmware 3.1.6, the DMR ID always seems to be removed when the repeater stops transmitting, (and goes back to showing the channel name), where as in 3.1.8 it always seems to hold on the DMR ID.
The operation of the DMR ID display is slightly intermittent on both 3.1.6 and 3.1.8, but I have not been able to reproduce the bug where the ID is not removed, when I use 3.1.6, however it seems easy to reproduce on 3.1.8
My guess is that this is a side effect of the ANI display system that has been added to display DTMF ID numbers, and is interfering with the DMR ID operation.
