Non-Latch of Repeater to the Network.

Post by F5VMR »

This is a difficult one to describe, as it is not a fault per se, but an anomaly that is requiring a further investigation.
From time to time a transmission I make to the MMDVM Repeater in DMR, gets the require Ack-Tone, but when I view the dashboard, the transmission is not showing. So I have dropped key, and re-tried getting the same Ack-tone, but this time the transmission proceeds to the network normally.

Code: Select all

This is an extract from the log at a point where I made three consecutive transmissions on TG2352. The first two were acknowledged and continued with Voice Sync, but the final transmission the voice header and sync was not interpreted. Although the Ack-Tone was heard.

Are any other MMDVM Users experiencing the same symptoms and is there a solution? The board in use is a ZUM-Radio Repeater Board in a Tait Repeater. The radio type is Chinese, but I've noticed these symptoms on all the radio's I possess, both portable & mobile. The settings for the Pi-Star are standard.

Indeed I had one Debug switch on true so I have changed that. I will give another test period before I take it further. I know I'm not the only one with this issue.
